Answer:
Step-by-step explanation:
We must simplify and rearrange the variables to divide x in order to determine the comparable inequality to the supplied inequality, -4(x + 7) 3(x - 2).
Below are the steps to solve the problem:
-4(x + 7) < 3(x - 2)
Expanding the equation:
-4x-28<3x-6
Gather the variable term on one side and constants on the other:
Adding -4x and 28 on both sides:
-4x + 4x - 28 + 28 < 3x + 4x - 6 + 28
=>0 < 7x + 22
To make the coefficient of x positive, we divide the entire inequality by 7:
0/7 < (7x + 22)/7
=> 0 < x + 22/7

Suppose the bear population in the Allegheny National Forest have weights that produce a normal density curve as shown.
74——————-200————————-326
From the graph shown, use the 69-95-99.7% (empirical) rule to estimate the standard deviation of the bear weights.
The estimated standard deviation of the bear weights, based on the given graph and using the 69-95-99.7% rule, is approximately 63.
The 69-95-99.7% (empirical) rule, also known as the 3-sigma rule, is a rule of thumb that applies to data that follows a normal distribution. According to this rule:
- Approximately 68% of the data falls within one standard deviation of the mean.
- Approximately 95% of the data falls within two standard deviations of the mean.
- Approximately 99.7% of the data falls within three standard deviations of the mean.
In the given graph, if we assume the bear weights follow a normal distribution, we can estimate the standard deviation using the 69-95-99.7% rule.
Based on the graph, we know that the midpoint of the distribution (mean) is 200. Assuming the graph is symmetric, we can estimate one standard deviation as half the distance between the mean (200) and either end (74 or 326).
To calculate this, we subtract the mean from one of the endpoints and divide by 2:
Standard Deviation ≈ (326 - 200) / 2 ≈ 126 / 2 ≈ 63

C. [13(\cos 23.5 - i\sin 23.5)\]
D. [13(\cos 23.6 - i\sin 23.6
The correct option is A. [13(cos 22.6 - isin 22.6)] in which the modulus is 13 and the argument is 22.6 degrees.
Given the complex number z = 12 + 5i. We have to express this complex number in the polar form which is\[z=r\cos\theta + i\sin\theta\]where r is the modulus and θ is the argument of the complex number.
The modulus of the complex number is given by,|z|=√(12²+5²)=√(144+25)=√169=13
Therefore, the modulus of the complex number is 13.
Now, we need to find the argument of the complex number, which is given byθ=tan⁻¹(b/a)Where a and b are the real and imaginary parts of the complex number z.θ=tan⁻¹(5/12)So, θ=22.6 degrees. (approximate value)
Thus, the complex number z = 12 + 5i can be expressed as\[z=13\cos(22.6^{\circ}) + i\sin(22.6^{\circ})

lion plays trumpet for a minmium of 45 mins on the days that he practices. if x is the number of days that lionel practices and y is the total number of hours he spends practicing, which inequality represents this situation
The inequality representing the situation is "y ≥ 0.75x," where y is the total number of hours Lionel spends practicing and x is the number of days he practices.
To represent the situation where Lionel practices for a minimum of 45 minutes on the days he practices, we can use the variables x and y, where x represents the number of days Lionel practices and y represents the total number of hours he spends practicing.
We know that Lionel practices for a minimum of 45 minutes on each day. Since there are 60 minutes in an hour, this is equivalent to 0.75 hours. Therefore, for each day Lionel practices, he spends at least 0.75 hours.
To find the total number of hours Lionel spends practicing (y), we can multiply the number of days he practices (x) by the minimum number of hours he spends on each day (0.75). This gives us the equation:
y ≥ 0.75x
This inequality states that the total number of hours Lionel spends practicing (y) must be greater than or equal to 0.75 times the number of days he practices (x). It ensures that Lionel practices for a minimum of 45 minutes (0.75 hours) on each day he practices.
By using this inequality, we can track Lionel's practice time and ensure that he meets the minimum requirement of 45 minutes per day.

On Day 10, Kelly will have a total of 20 pennies in her penny jar.
To determine how many pennies Kelly will have on Day 10, we need to consider the progression of pennies added to her jar each day.
On Day 1, Kelly starts with 2 pennies. On Day 2, she adds 2 more pennies, resulting in a total of 2 + 2 = 4 pennies. This pattern continues, with 2 more pennies being added each day.
To find the number of pennies on Day 10, we can observe that the number of pennies on any given day can be calculated using the formula:
Number of pennies = Initial number of pennies + (Number of days - 1) * Number of pennies added per day
Using the provided information, we can substitute the values into the formula:
Number of pennies on Day 10 = 2 + (10 - 1) * 2

faste او انوار کو کسی Q2. 3 balls are drawns from the box containing six white balls five red balls and four blue balls find the probabi- lity. that they are draw from the other blue red and white if each ball is (i) Replaced (ii) Not replace.
The probability of drawing blue, red, and white balls consecutively is 120/3375 with replacement and 120/2730 without replacement.
To calculate the probability of drawing three balls from a box containing six white balls, five red balls, and four blue balls, we need to consider two scenarios: with replacement and without replacement.
(i) With replacement:
When each ball is replaced after it is drawn, the total number of balls remains the same for each draw. Therefore, the probability of drawing a specific color on each draw remains constant.
The probability of drawing a blue ball on each draw is 4/15, the probability of drawing a red ball is 5/15, and the probability of drawing a white ball is 6/15 (assuming all colors are equally likely to be drawn).
To find the probability of drawing a blue, red, and white ball consecutively, we multiply the probabilities together since the events are independent:
P(Blue, Red, White) = (4/15) * (5/15) * (6/15) = 120/3375
(ii) Without replacement:
When the balls are not replaced after being drawn, the total number of balls decreases for each subsequent draw. This affects the probability of each color being drawn on subsequent draws.
For the first draw, the probability of drawing a blue ball is 4/15, a red ball is 5/15, and a white ball is 6/15.
For the second draw, the probability of drawing a blue ball is 3/14, a red ball is 5/14 (as one blue ball is already drawn), and a white ball is 6/14.
For the third draw, the probability of drawing a blue ball is 2/13, a red ball is 4/13 (as two blue balls and one red ball are already drawn), and a white ball is 6/13.
To find the probability of drawing a blue, red, and white ball consecutively without replacement, we multiply the probabilities together:
P(Blue, Red, White) = (4/15) * (5/14) * (6/13) = 120/2730
Therefore, the probability of drawing blue, red, and white balls consecutively is 120/3375 with replacement and 120/2730 without replacement.

1. Brandon went to a Formula One car race and used his stopwatch to time how fast his favorite driver, Fernando Alonso, went around the 4.7-kilometer track. Brandon started the timer at the beginning of the second lap, when the cars were already going fast. When he stopped the timer at the beginning of the third lap, one minute and three seconds had passed.
b. If you graphed the distance Fernando had traveled at the beginning of the lap and at the end of the lap, what would the coordinates of these points be? What would the
- and
-axes on this graph represent?
c. Find the equation of the line between these two points. What does this line represent?
d. If Fernando continues to average this speed, about how long do you think it would take him to finish the entire race? The race is 500 km.
Step-by-step explanation:
b. To determine the coordinates of the points on the graph, we need to consider the information given.
At the beginning of the second lap, one minute and three seconds had passed. Since each lap is 4.7 kilometers long, we can calculate the distance traveled at the beginning of the lap using the formula:
Distance = (Number of laps - 1) × Length of each lap
For the beginning of the second lap:
Distance = (2 - 1) × 4.7 km = 4.7 km
At the beginning of the third lap, one minute and three seconds had passed. Therefore, the distance traveled at the beginning of the third lap is:
Distance = (3 - 1) × 4.7 km = 9.4 km
The coordinates of the points on the graph would be:
Point A: (4.7 km, 4.7 km)
Point B: (9.4 km, 9.4 km)
On the graph, the x-axis would represent the distance traveled at the beginning of the lap, and the y-axis would represent the distance traveled at the end of the lap.
c. To find the equation of the line between the two points, we can use the slope-intercept form of a linear equation:
y = mx + b
where m is the slope and b is the y-intercept.
Using the coordinates of the two points (4.7 km, 4.7 km) and (9.4 km, 9.4 km), we can calculate the slope:
m = (y2 - y1) / (x2 - x1)
= (9.4 km - 4.7 km) / (9.4 km - 4.7 km)
= 4.7 km / 4.7 km
= 1
The slope of the line is 1.
Since the line passes through the origin (0, 0), the y-intercept (b) is 0.
Therefore, the equation of the line is:
y = 1x + 0
y = x
This line represents a one-to-one relationship between the distance traveled at the beginning of the lap and the distance traveled at the end of the lap.
d. To estimate how long it would take Fernando to finish the entire race if he continues to average the same speed, we need to find the time it takes for one lap.
In the given scenario, Brandon timed Fernando's lap for one minute and three seconds. Since there are 3 laps in total, we can divide the total time by the number of laps to find the average time per lap:
Average time per lap = Total time / Number of laps
= 1 minute and 3 seconds / 3
= 21 seconds
Since each lap is 4.7 kilometers long, we can calculate the speed:
Speed = Distance / Time
= 4.7 km / (1 minute + 21 seconds)
To estimate the time it would take Fernando to finish the entire race, we divide the total race distance by the speed:
Total race time = Total race distance / Speed
= 500 km / (4.7 km / (1 minute + 21 seconds))
To calculate the time, we need to convert 1 minute and 21 seconds to a decimal form:
1 minute + 21 seconds = 1 minute + (21 seconds / 60 seconds)
= 1 minute + 0.35 minutes
= 1.35 minutes
Substituting the values:
Total race time = 500 km / (4.7 km / 1.35 minutes)
= 500 km × (
1.35 minutes / 4.7 km)
= 500 km × 0.28723...
≈ 143.615 minutes
Therefore, it would take approximately 143.615 minutes for Fernando to finish the entire race if he continues to average the same speed.

1. Find (f + g)(1), when f(x) = x + 6 and g(x) = x - 3.
Answer:
(f + g)(1) = 5
Step-by-step explanation:
(f + g) means we are going to add f(x) and g(x). But also, the (1) part means we are going to let x be equal to 1. We're going to fill in 1 in place of x. You can do this in either order.
Generally speaking its "easier" to fill in the 1 for x first and then do the adding part.
f(x) = x + 6
f(1) = 1 + 6 = 7
and,
g(x) = x - 3
g(1) = 1 - 3 = -2
add the 7 and -2 together:
7 + - 2
= 5
It works out the same if you add first:
f(x) + g(x)
= x + 6 + x - 3
= 2x + 3
then put the 1 in:
= 2×1 + 3
= 2 + 3
= 5

You are working on your second project as an equity research intern at a bulge investment bank. Your focus is in retail space, especially in the health and fitness sector. Currently, you are gathering information on a fast-growing chain fitness company called LuluYoga. You are interested in calculating the free cash flow of the firm.
LuluYoga offers yoga classes in several major cities in the United States. Two major revenue resources are selling workout gear and membership passes for class access.
Assume at the beginning of year 2016, LuluYoga has zero inventory.
In year 2016, LuluYoga purchased 10,000 yoga mats at a price of $10 each. The company sells 6,000 mats at a price of $15 in year 2016 and sells the remaining at a price of $20 in year 2017.
In year 2016, LuluYoga sells 1,000 membership passes for $2,000 each. 80% of the classes purchased were used in 2016 and the rest are used in 2017.The yoga master’s compensation to teach classes are $300K in year 2016 and $200K in year 2017.
LuluYoga pays corporate tax of 35%
What is the deferred revenue in 2016?
The number of membership passes that will contribute to deferred revenue in 2016 is: 1,000 (total passes sold) x 20% (passes utilized in 2017) = 200 passes.
To calculate the deferred revenue in 2016 for LuluYoga, we need to consider the membership passes that were sold but not yet utilized.
In 2016, LuluYoga sold 1,000 membership passes for $2,000 each. We know that 80% of the classes purchased were used in 2016, which means 20% of the classes will be utilized in 2017.
Therefore, the number of membership passes that will contribute to deferred revenue in 2016 is:
1,000 (total passes sold) x 20% (passes utilized in 2017) = 200 passes
The revenue generated from these 200 passes will be realized in 2017 when the classes are utilized. Therefore, the revenue from these passes should be deferred to the following year.
To calculate the deferred revenue, we need to multiply the number of passes by the price per pass:
200 (passes) x $2,000 (price per pass) = $400,000
Hence, the deferred revenue in 2016 for LuluYoga is $400,000.
Deferred revenue represents the amount of revenue that has been received but has not yet been earned. In this case, LuluYoga has received payment for the membership passes, but the revenue associated with the unused classes will be recognized in the subsequent year when the classes are actually utilized.

You have 3 molecules of H2SO4, each molecule has two atoms of H and you have 3 molecules, so 3*2=6 atoms of H
two points A and B, due to two spheres X and Y 4.0m apart, that are carrying charges of 72mC and -72mC respectively. Assume constant of proportionality as 9×10^9Nm²/C². Find the electric field strength at points A and B due to each spheres presence
Point B: Electric field strength due to sphere X = 2073.6 NC⁻¹ and Electric field strength due to sphere Y = -2073.6 NC⁻¹.
data: Spheres X and Y are 4.0 m apart. The charge on sphere
X = + 72 mC = 72 × 10⁻³ C.
The charge on sphere
Y = -72 mC = -72 × 10⁻³ C.
The constant of proportionality = 9 × 10⁹ Nm²/C².
The formula to calculate the electric field strength due to a point charge is
E = k q / r²
where E is the electric field strength, k is the Coulomb's constant (= 9 × 10⁹ Nm²/C²), q is the magnitude of the charge, and r is the distance from the charge.The electric field due to sphere X at point A is
EaX = [tex]k q / r²where r = 4.0 m, q = + 72 × 10⁻³ CSo, EaX = 9 × 10⁹ × 72 × 10⁻³ / (4.0)²EaX = 9 × 9 × 2 × 2 × 2 × 2 / 10[/tex]EaX = 2592 / 10EaX = 259.2
NC⁻¹The electric field due to sphere Y at point A is
[tex]EaY = k q / r²where r = 4.0 m, q = -72 × 10⁻³ CSo, EaY = 9 × 10⁹ × 72 × 10⁻³ / (4.0)²EaY = -9 × 9 × 2 × 2 × 2 × 2 / 10EaY = -2592 / 10EaY = -259.2[/tex]
NC⁻¹The electric field due to sphere X at point B is
[tex]EbX = k q / r²where r = 4.0 m, q = + 72 × 10⁻³ C + 72 × 10⁻³ C = 144 × 10⁻³ C.So, EbX = 9 × 10⁹ × 144 × 10⁻³ / (4.0)²EbX = 9 × 9 × 4 × 4 × 4 × 4 / 10EbX = 20736 / 10EbX = 2073.6[/tex]
NC⁻¹The electric field due to sphere Y at point B is
[tex]EbY = k q / r²where r = 4.0 m, q = -72 × 10⁻³ C - 72 × 10⁻³ C = -144 × 10⁻³ C. So, EbY = 9 × 10⁹ × -144 × 10⁻³ / (4.0)²EbY = -9 × 9 × 4 × 4 × 4 × 4 / 10EbY = -20736 / 10EbY = -2073.6 NC⁻¹[/tex]
Therefore, the electric field strength at points A and B due to each sphere's presence are: Point A: Electric field strength due to sphere X = 259.2 NC⁻¹ and Electric field strength due to sphere Y = -259.2 NC⁻¹.

5. m∠SQR=130°
Subtraction Property of Equality
6. ∠SQR
is an obtuse angle. Definition of obtuse angle
The reason for Statement 2 in the two-column proof is the Angle Addition Postulate.The Angle Addition Postulate states that if two angles share a common vertex and a common side, then the sum of the measures of those angles is equal to the measure of the larger angle formed by the two sides.
In the given proof, Statement 1 states that the measure of angle PQS is 50 degrees. Statement 2 follows from the Angle Addition Postulate because angles PQS and SQR share the common vertex Q and the common side QS.
Since angle PQS is given as 50 degrees, and angles PQS and SQR are supplementary (which means their measures sum up to 180 degrees), we can use the Angle Addition Postulate to conclude that the measure of angle SQR is 180 - 50 = 130 degrees. This is shown in Statement 5.
Finally, Statement 6 states that angle SQR is an obtuse angle. This follows from the definition of an obtuse angle, which states that an angle is obtuse if its measure is greater than 90 degrees but less than 180 degrees. Since angle SQR measures 130 degrees, it falls within the range of obtuse angles.

rate.
C. Hannah's unit rate is equal to Becky's unit rate.
D. Hannah's unit rate is 1 fewer word per minute than Becky's unit
rate
The correct statement is D. Hannah's unit rate is 1 fewer word per minute than Becky's unit rate.
To compare the unit rates, we need to determine the rate at which each person types words per minute.
For Hannah, the equation y = 11x represents her typing speed, where y is the number of words and x is the number of minutes. This means that Hannah types 11 words per minute (11 words/minute).
Looking at Becky's graph, we can determine her unit rate by calculating the change in the number of words divided by the change in time.
The change in words is 48 - 2 = 46, and the change in time is 3 - 2 = 1. So, Becky's unit rate is 46 words per minute (46 words/minute).
Comparing the unit rates:
Hannah's unit rate: 11 words/minute
Becky's unit rate: 46 words/minute
Therefore, Hannah's unit rate is 35 words per minute less than Becky's unit rate.

A right circular cone is intersected by a plane that passes through the cone's
vertex and is perpendicular to its base, as in the picture below. What is
produced from this intersection?
OA. A pair of parallel lines
B. A single line
OC. A point
OD. A pair of intersecting lines
Answer:
D. A pair of intersecting lines
Step-by-step explanation:
A conic section is a fancy name for a curve that you get when you slice a double cone with a plane. Imagine you have two ice cream cones stuck together at the tips, and you cut them with a knife. Depending on how you cut them, you can get different shapes. These shapes are called conic sections, and they include circles, ellipses, parabolas and hyperbolas. If you cut them right at the tip, you get a point. If you cut them slightly above the tip, you get a line. If you cut them at an angle, you get two lines that cross each other. That's what happened in your question. The plane cut the cone at an angle, so the curve is two intersecting lines. That means the correct answer is D. A pair of intersecting lines.

A charged particle produces an electric field with a magnitude of 2.0 N/C at a point that is 50 cm away from the particle. a) Without finding the charge of the particle, determine the electric field produced by this charge at a point 25 cm away from it. b) What will happen to the Electric field at the distance 50 cm, if you double the charge? c) What is the magnitude of the particle’s charge?
To solve these problems, we can use Coulomb's Law, which states that the magnitude of the electric field produced by a charged particle is directly proportional to the charge and inversely proportional to the square of the distance from the particle.
a) Without finding the charge of the particle, we can use the inverse square relationship. If the electric field magnitude is 2.0 N/C at a distance of 50 cm, then at half the distance (25 cm), the electric field would be four times stronger. Therefore, the electric field at 25 cm would be 4 * 2.0 N/C = 8.0 N/C.
b) Doubling the charge would result in doubling the electric field magnitude. So, if the electric field at a distance of 50 cm was initially 2.0 N/C, it would become 4.0 N/C after doubling the charge.
c) To determine the magnitude of the particle's charge, we need to use the equation for the electric field:
E = k * (|q| / r^2)
where E is the electric field magnitude, k is the electrostatic constant, |q| is the magnitude of the charge, and r is the distance from the particle.
Using the known values of E = 2.0 N/C and r = 50 cm (or 0.5 m), we can rearrange the equation to solve for |q|:
|q| = E * r^2 / k
Substituting the values and the known value of k, we can calculate the magnitude of the charge.

The reason why Figure A is congruent to Figure C is that they undergo the same sequence of transformations: a translation followed by a reflection.
The statement "Figure A is translated 3 units right and 2 units up. The translated figure is labeled Figure B. Figure B is reflected over the x-axis. The reflected figure is labeled Figure C" describes a sequence of transformations applied to Figure A to obtain Figure C.
When Figure A is translated 3 units right and 2 units up, it undergoes a rigid transformation known as a translation. This transformation preserves the shape and size of the figure. The translated figure, Figure B, will have the same dimensions and orientation as Figure A but will be shifted to the right and up.
When Figure B is reflected over the x-axis, it undergoes a reflection. This transformation flips the figure vertically, changing the sign of the y-coordinates of its vertices while keeping the x-coordinates the same. The reflected figure, Figure C, will have the same shape and size as Figure B, but it will be oriented in the opposite direction.
Since translations and reflections are both rigid transformations, they preserve congruence. Therefore, Figure A and Figure C are congruent because they undergo the same sequence of transformations (translation followed by reflection) from Figure A.
In conclusion, Figures A and C go through the same set of transformations, a translation and a reflection, which explains why they are congruent.

b .) The amount received by the daughter would be =G Hç 2176
c.) The difference between the amount the two sons received would be =GHç1,904
How to calculate the amount received by the eldest son?For 1a.)
The amount that the land is worth= $8,600
The amount received for various purposes= $1,800
The remaining amount shared to the sons= 8,600-1800= $6,800
The percentage amount received by the eldest son= 20% of 6800
That is;
= 20/100×6800/1
= 136000/100
= $1,360
The remaining amount= 6800-1360= $5,440
For 1b.)
The ratio that the remaining amount was shared between the other son and the daughter = 3 : 2 respectively.
The total ratio= 3+2=5
For daughter= 2/5× 5440
= 10880/5 = 2176
