Solve the inequality.
-3(4n+1) < -6(2n-6)
Answer:
no solution
Step-by-step explanation:
Given :
-3(4n+1) < -6(2n-6)
Divide by -3 on each side (and remember to change the sign) :
-1/3 x -3(4n+1) < -1/3 x -6(2n-6)
4n + 1 > 2(2n - 6)
Expand the RHS :
4n + 1 > 2(2n) - 2(6)
4n + 1 > 4n - 12
Solution :
As the coefficient of x is the same on both sides, and the constants are different, this inequality has no solution
Answer:
Given inequality:
-3(4n + 1) < -6(2n - 6)
Expand the brackets:
⇒ -12n - 3 < -12n + 36
Add 12n to both sides:
⇒ -12n - 3 + 12n < -12n + 36 + 12n
⇒ -3 < 36
Solution: True for all n

the triangle on the right has 2 sides the same so the lower two corners have the same angle which would be (180-64)/2 = 58 degrees
the lower right angle of the triangle on the left Sadie would be 180-58 = 122.
Since 2 sides of the triangle on the left are the same the other two angles would be equal to each other.
x = (180-122)/2 = 29 degrees
Answer:
x = 29°
Explanation:
The triangle on right side is an isosceles triangle with two similar angles.
Let that angle be z:
⇒ z + z + 64° = 180°
⇒ 2z = 180° - 64°
⇒ 2z = 116°
⇒ z = 58°
After finding z, find the opposite angle:
⇒ 180° - 58° = 122°
Find the value of x:
⇒ x + x + 122° = 180°
⇒ 2x = 180° - 122°
⇒ 2x = 58°
⇒ x = 29°

What is the ratio of the difference in the means of the two teams to the mean absolute deviation of Team B?
0.09
0.15
0.25
0.65
The correct answer is option C which is the ratio of the difference in the means of the two teams to the mean absolute deviation of Team B will be 0.25.
What is mean?Mean is defined as the ratio of the sum of the number of the data sets to the total number of the data.
The difference between the mean times is about 16 times the mean absolute deviation of the data set.
59.32 - 59.1 = 0.22
2.4 - 1.5 = 0.9
0.22 / 0.9 = 0.25
Therefore the correct answer is option C which is the ratio of the difference in the means of the two teams to the mean absolute deviation of Team B will be 0.25.

Often, it seems like the question is answered once the value of x is found. Here, finding the value of x is an intermediate step. The value of x is needed in order to be able to answer the question about the value of an expression involving x.
Answer:
10
Step-by-step explanation:
→ Equate both sides of the parallelogram as they are equal
2x = x + 5
→ Solve
x = 5
→ Resubstitute for the length AD

The length of a rectangle is 3m less than double the width, and the area of the rectangle is 65m^2 .
What is the length & width of the rectangle?
By solving a quadratic equation, we will see that the length is 10m and the width is 6.5m
How to find the length and width of the rectangle?For a rectangle of width W and length L, the area is:
A = W*L
In this case, we know that the area is 65m² and that the length is 3 meters less than 2 times the width, so:
L = 2*W - 3m
Then we can write:
65m² = (2*W - 3m)*W = 2*W² - 3m*W
This is a quadratic equation:
2*W² - 3m*W - 65m² = 0.
The solutions are given by the Bhaskara's formula:
[tex]W = \frac{3 \pm \sqrt{(-3)^2 - 4*2*(-65)} }{2*2} \\\\W = \frac{3 \pm 23 }{4}[/tex]
We only care for the positive solution, which is:
W = (3m + 23m)/4 = 26m/4 = 6.5m
Then the length is:
L = 2*6.5m - 3m = 10m

The total sales of the year after is Rs. 1857143
How to find the total sales after commission?He gets 1.5% commission on the total annual sales and a bonus of 2% on the sales above Rs. 20,00,000.
Therefore, since he received a bonus, the sale is over Rs. 20,000.
Hence,
let
x = total sales
Therefore,
1.5% of x + 2% of x = 65000
1.5 / 100 × x + 2 / 100 × x = 65000
0.015x +0.02x = 65000

Find the common denominator needed to subtract the following fractions. 5/6 -2/7 =
Answer:
42
Step-by-step explanation:
We need to find the Least Common Multiple (that isn't 0) between 6 and 7. To do this, list each number's multiples.
Multiples of 6: 0, 6, 12, 18, 24, 30, 36, 42, 48, 54
Multiples of 7: 0, 7, 14, 21, 28, 35, 42, 49, 56, 63
Their LCM is 42. Now, we multiply the fractions so the denominators are both 42. !You have to multiply both the numerator and denominator by the same number! For 6, 6*7 is 42, so you multiply both 6 and 5 by 7. When you do this, you get 35/42. For 7, 7*6 is 42, so you have to multiply both 7 and 2 by 6. When you do this, you get 12/42. The new problem is 35/42-12/42.

Jill, Ally, and Maria ran the 50-yard dash. Jill ran the race in 6.87 seconds. Ally ran the race in 6.82 seconds. Maria ran the race in 6.93. Who ran the race the fastest? Explain how you can use a place-value chart to find the answer.
Answer:
Ally
Step-by-step explanation:
The fastest time of the race will be the one lesser in value.
=============================================================
Comparing the tenths place :
⇒ Jill = 8 in the tenths place
⇒ Ally = 8 in the tenths place
⇒ Maria = 9 in the tenths place
Since Maria's time's tenth place value is greater than that of the other two, she had the slowest time.
===========================================================
Comparing the hundredths place (for Jill and Ally) :
⇒ Jill = 7 in the hundredths place
⇒ Ally = 2 in the hundredths place
Since Ally has the lower hundredths' place value, she has the fastest time.
The weight of a bag of Brand A cookies is labeled as 3 ounces on the bag. However, the actual weights of the bags vary by a small amount. According to the packaging specifications, the weights are approximately normally distributed with a mean of 3.05 ounces and a standard deviation of 0.06 ounce. Select the number to complete the sentence. According to the specifications, approximately percent of the bags weigh 3.00 ounces or more
Using the normal distribution, it is found that approximately 79.67% of the bags weigh 3.00 ounces or more.
Normal Probability DistributionThe z-score of a measure X of a normally distributed variable with mean [tex]\mu[/tex] and standard deviation [tex]\sigma[/tex] is given by:
[tex]Z = \frac{X - \mu}{\sigma}[/tex]
The z-score measures how many standard deviations the measure is above or below the mean. Looking at the z-score table, the p-value associated with this z-score is found, which is the percentile of X.The mean and the standard deviation are given, respectively, by:
[tex]\mu = 3.05, \sigma = 0.06[/tex]
The proportion of the bags that weigh 3.00 ounces or more is one subtracted by the p-value of Z when X = 3, hence:
[tex]Z = \frac{X - \mu}{\sigma}[/tex]
[tex]Z = \frac{3 - 3.05}{0.06}[/tex]
Z = -0.83
Z = -0.83 has a p-value of 0.2033.
1 - 0.2033 = 0.7967 = 79.67%.
79.67% of the bags weigh 3.00 ounces or more.

Answer:
Knowledge > Probability
Step-by-step explanation:
In the moment knowledge would be useful because you are thinking about the decision you are making but after days, months or years probability would be in your mind. Also probability is just another word for chance so there would be no confirmation of said thing happening but when you have knowledge your brain knows that said thing is 100% going to happen, so for me personally knowledge is more useful than probability
