the probability that Juan will catch at least 10 passes out of 15 is approximately 0.9951, or about 99.51%.
We may utilise the binomial distribution formula to resolve this issue:
P(X ≥ 10) = 1 - P(X < 10)
where P(X 10) is the likelihood that Juan catches fewer than 10 passes and X is the total number of passes he catches.
By applying the binomial distribution formula, we may determine P(X 10):
P(X < 10) = Σ(k=0 to 9) [(15 select k)×(0.8)k×(0.2)×(15-k)]
where (15 select k) is the binomial coefficient and (0.8)k×(0.2)(15-k) is the probability of catching k passes and missing (15-k) passes, and (15 choose k) is the number of possibilities to choose k items out of 15.
P(X 10) can be calculated using a calculator or a spreadsheet and is roughly equal to 0.0049.
P(X 10) is therefore equal to 1 - P(X 10) 1 - 0.0049 0.9951.
So the probability that Juan will catch at least 10 passes out of 15 is approximately 0.9951, or about 99.51%.

Mamadou has 64 m of fencing to build a four-sided fence around a rectangular plot of land. The area of the land is 247 square meters. Solve for the dimensions (length and width) of the field.
Answer: The length and width are 13 and 19
Step-by-step explanation:
This is because the factors of 247 are 1, 13, 19, and 247. 13 times 19 is 247, but if 13 and 19 are the sides, the perimeter would be 64 as well.
Margarita borrows $14,000 from her uncle and agrees to repay it in monthly installments of $400. Her uncle charges 0.9% interest per month on the balance.
(a) If her balance An in the nth month is given recursively by A0 = 14,000 and An = k · An − 1 − 400, what is k?
(b) Find her balance after two months. (Round your answer to the nearest cent.)
Answer:
Step-by-step explanation:
(a) We know that the balance An in the nth month is given by:
An = k · An-1 - 400
where A0 = 14,000. Substituting n = 1, we get:
A1 = k · A0 - 400
A1 = k · 14,000 - 400
We also know that her uncle charges 0.9% interest per month on the balance. This means that the balance after one month should be:
A1' = A0 + 0.009 · A0 - 400
A1' = 14,000 + 0.009 · 14,000 - 400
A1' = 14,126
Setting A1 = A1', we can solve for k:
k · 14,000 - 400 = 14,126
k = 1.009
Therefore, k is approximately 1.009.
(b) To find her balance after two months, we can use the recursive formula with n = 2:
A2 = k · A1 - 400
A2 = 1.009 · 14,126 - 400
Using a calculator, we get:
A2 ≈ 14,272.34
Therefore, her balance after two months is approximately $14,272.34.

$29.95 per day. Mileage is charged at a rate of $0.25 per mile with the first 500 miles free. He
rents the vehicle for 10 days, drives it 865 miles, and spends $62 on gasoline. What is the cost
per mile of renting the vehicle?
The cost of renting the vehicle per mile is $0.524.
How to determine the cost per mile of renting the vehicleTo get the cost per mile of renting a vehicle, multiply the total cost of renting the vehicle by the total number of miles driven.
The rental cost:
10 days multiplied by $29.95 per day equals $299.50.
The total rental cost is $299.50.
The mileage cost:
865 miles minus 500 free miles equals 365 miles.
365 miles multiplied by $0.25 each mile equals $91.25.

Each week, the company has 700 hours of labor, 3360 feet of wood, and 60 gallons of stain. The company makes $10 in profit per bar stool, $25 in profit per chair, and $35 in profit per table. In order to maximize their profit, the furniture company should make
In the given problem, the furniture company should produce 300 bar stools and 50 chairs to maximize their profit, and should not produce any tables.
How to solve the Problem?To maximize profit, the furniture company needs to determine how many units of each product (bar stools, chairs, and tables) they should produce. Let's use x, y, and z to represent the number of bar stools, chairs, and tables respectively.
The objective function to maximize profit is:
Profit = 10x + 25y + 35z
The company has constraints on the amount of labor, wood, and stain available. These constraints can be expressed as follows:
Labor: 1x + 4y + 2z ≤ 700 (the company has 700 hours of labor available each week)
Wood: 8x + 16y + 32z ≤ 3360 (the company has 3360 feet of wood available each week)
Stain: 0.2x + 0.4y + 0.5z ≤ 60 (the company has 60 gallons of stain available each week)
Also, since we cannot produce negative units of any product, we must add the constraint that x, y, and z are all non-negative.
x ≥ 0, y ≥ 0, z ≥ 0
We can now use linear programming techniques to solve this problem. One possible method is the simplex method, which involves converting the problem into an augmented matrix and applying row operations until we obtain the optimal solution.
The optimal solution is:
x = 300 (produce 300 bar stools)
y = 50 (produce 50 chairs)
z = 0 (do not produce any tables)
The maximum profit that the company can earn is:
Profit = 10x + 25y + 35z = 10(300) + 25(50) + 35(0) = $3,250
Therefore, the furniture company should produce 300 bar stools and 50 chairs to maximize their profit, and should not produce any tables.

12. A new software package is expected to improve productivity at X company. However, because of training and implementation costs, savings are not expected to occur until the third year of operation. At that time, savings of $10,000 are expected, increasing by $1,000 per year for the following five years. After this time (eight years from implementation), the software will be abandoned with no scrap value. How much is the software worth today, at 15% interest?
Okay, here are the steps to solve this problem:
1) Savings start in year 3 at $10,000.
2) Savings increase by $1,000 each year for 5 years, so years 4-8 savings are $11,000, $12,000, $13,000, $14,000, $15,000.
3) There are 8 years of savings total.
4) Interest rate is 15%.
To calculate the present value at year 0 (today), we use the following formula:
PV = FV / (1 + r)^n
Where FV is the future value, r is the interest rate, and n is the number of years.
So for year 3 savings of $10,000:
PV = $10,000 / (1 + 0.15)^3 = $8,562
For year 4 savings of $11,000:
PV = $11,000 / (1 + 0.15)^4 = $8,948
And so on...
Adding up the present values for years 3 to 8:
$8,562 + $8,948 + $9,371 + $9,820 + $10,298 + $10,796 + $11,310 + $11,842 = $80,847
Therefore, the total present value of the 8 years of savings is $80,847.
So the software is worth $80,847 today at a 15% interest rate.

What is an arc of circle?A circle's circumference may be divided up into arcs. It is described as the curved line that divides a circle into segments by joining two points on its circumference. An arc's length is inversely proportional to the angle it forms at the circle's centre.
The length of the arc increases with increasing central angle, and vice versa. In geometry, trigonometry, and physics, arcs are frequently employed to represent and compute measurements of circles and circular objects.
For given problem,
mGC = 105° and
mFDG= 360° - mGF (∵ Total arc or angle of circle is 360°)
(As, mGF=mFC-mGC)
= 360°-(180°-mGC) (Assuming FC is a diameter making mFC=180°)
= 360°-(180°-105°) (∵mGC = 105°)

A planter box has dimensions 30 in × 15 in × 18 in (Length × Width × Height).
a. Find the volume of the box in cubic feet and in cubic yards.
b. Potting soil is sold in 1.5 cubic-foot bags, and each bag weighs 11.2 pounds. How many
pounds of soil does the box hold?
c. You’d like to paint the sides (but not the bottom) of the planter box. You plan on
applying one coat of paint. How many square feet of paint will you need?
88
Okay, let's solve this step-by-step:
a)
Length = 30 in = 2.5 ft
Width = 15 in = 1.25 ft
Height = 18 in = 1.5 ft
Volume (cubic ft) = Length x Width x Height
= 2.5 x 1.25 x 1.5 = 3.75 cubic ft
Volume (cubic yards) = 3.75 / 27 = 0.14 cubic yards
b)
Since the box volume is 3.75 cubic ft and potting soil bags are 1.5 cubic ft,
you will need 3.75 / 1.5 = 2.5 bags of soil.
Each bag weighs 11.2 lbs, so 2.5 bags will weigh 2.5 * 11.2 = 28 lbs of soil.
c)
To paint the sides of the box, you need:
Length (2 sides) = 30 in x 2 = 60 in
Width (2 sides) = 15 in x 2 = 30 in
Height (4 sides) = 18 in x 4 = 72 in
Total inches of sides = 60 + 30 + 72 = 162 in
Conversion: 162 in / 12 in = 13.5 square ft
So you will need about 14 square feet of paint.

a. A bag contains 4 red marbles, 5 yellows marbles, and 7 whites marbles. If a marble is drawn from the bag, replaced, and another marble is drawn,
what is the probability of drawing first a marble and then a marble?
Answer: 5/64
Step-by-step explanation:
The probability of drawing a red marble on the first draw is 4/16 = 1/4 (since there are 4 red marbles out of 16 total marbles).
After replacing the first marble, the probability of drawing a yellow marble on the second draw is 5/16 (since there are 5 yellow marbles remaining out of 16 total marbles).
Therefore, the probability of drawing a red marble and then a yellow marble is (1/4) x (5/16) = 5/64
I don't understand how you substituted the equation of this question noted the length,d m,of a rectangular field is 40m greater than the width. The perimeter of the field is 400m . Kindly simplify
The width of the rectangular field is 80 meters and the length is 120 meters for the given perimeter 400m.
What is the perimeter?Perimeter is a mathematical term that refers to the total distance around the outside of a closed two-dimensional shape. It is the sum of the lengths of all the sides of the shape.
According to the given information:
Let's break down the information given in the question:
Length of the rectangular field is 40m greater than the width.
The perimeter of the field is 400m.
Let's denote the width of the rectangular field as 'w' meters. According to the first information, the length of the field would be 'w + 40' meters, as it is 40m greater than the width.
Now, let's use the formula for the perimeter of a rectangle, which is given by:
Perimeter = 2 * (Length + Width)
Substituting the values we have:
Perimeter = 2 * (w + 40 + w)
Perimeter = 2 * (2w + 40)
Since the given perimeter is 400m, we can set up the equation:
400 = 2 * (2w + 40)
Now we can solve for 'w' by dividing both sides of the equation by 2:
400/2 = 2w + 40
200 = 2w + 40
Next, we subtract 40 from both sides of the equation to isolate the term with 'w':
200 - 40 = 2w
160 = 2w
Finally, we divide both sides of the equation by 2 to solve for 'w':
160/2 = w
80 = w
So, the width of the rectangular field is 80 meters. And since the length is 40 meters greater than the width, the length would be:
Length = Width + 40 = 80 + 40 = 120 meters.
So, the width of the rectangular field is 80 meters and the length is 120 meters.

After 12 years, the environment can no longer support the population growth. (option a).
Population growth is a fundamental concept in ecology and biology. It refers to the increase in the number of organisms in a population over time.
The carrying capacity is the maximum number of individuals of a particular species that can be supported by the environment without degrading it. In this case, the carrying capacity of the environment is 600 organisms. When the population reaches this limit, the environment can no longer support the population, and the growth rate slows down until it reaches equilibrium.
The table provides the approximate number of organisms after y years. To determine when the environment can no longer support the population, we need to find the year when the population exceeds the carrying capacity of the environment. In other words, we need to find the year when the population reaches or exceeds 600 organisms.
Looking at the table, we can see that the population reaches 600 organisms in the year 12.

adam bought a skateboard that is on sale for 35% off the original cost is 150 what is the sale price
Answer:
$97.50
Step-by-step explanation:
To calculate the sale price of the skateboard, we need to apply a discount of 35% to the original cost of $150:
Discount amount = 35% x $150 = $52.50
The sale price is the original cost minus the discount amount:
Sale price = $150 - $52.50 = $97.50
Therefore, the sale price of the skateboard after a 35% discount is $97.5
The sale price of the skateboard is $97.50.
To calculate the sale price, we need to first determine the amount of the discount, and then subtract that discount from the original price.
The discount is 35% of the original price:
Discount = 0.35 x 150 = 52.50
So the sale price is the original price minus the discount:
Sale price = 150 - 52.50 = 97.50

Which car should Andre buy? How many more miles per gallon can he
drive in this car than the other car?
Answer: Andre should buy Car 2. Brainliest?
Step-by-step explanation:
To compare the gas mileage of the two cars, we need to find out how many miles each car can travel per gallon of gas.
For Car 1: y = 25x
This means that for every gallon of gas used (x), the car can travel 25 times that amount in miles (y). So, the gas mileage for Car 1 is 25 miles per gallon (mpg).
For Car 2: we can calculate the miles per gallon by dividing the total miles traveled by the number of gallons of gas used:
For 2 gallons of gas, the car can travel 60 miles. So, the gas mileage is 30 mpg (60 miles ÷ 2 gallons).
For 5 gallons of gas, the car can travel 150 miles. So, the gas mileage is 30 mpg (150 miles ÷ 5 gallons).
For 7 gallons of gas, the car can travel 210 miles. So, the gas mileage is 30 mpg (210 miles ÷ 7 gallons).
For 8 gallons of gas, the car can travel 240 miles. So, the gas mileage is 30 mpg (240 miles ÷ 8 gallons).
For 11 gallons of gas, the car can travel 330 miles. So, the gas mileage is 30 mpg (330 miles ÷ 11 gallons).
Therefore, Car 2 has a consistent gas mileage of 30 mpg.
From the above calculations, we can see that Car 2 has a better gas mileage compared to Car 1. Car 2 can travel 30 miles on a gallon of gas, while Car 1 can only travel 25 miles on a gallon of gas.
Therefore, Andre should buy Car 2 if he wants to get the best gas mileage. Car 2 can travel 5 more miles per gallon than Car 1.

Algebra II (2019) Sem 2 L 1.8.4 Quiz: More Than One Vertical Asymptote Question 2 of 10 Which of the following rational functions is graphed below? O A. F(x) = B. F(x) = x(x+3)(x-3) (x-3)(x+3) ○ C. F(x) = x(x-3) ○ D. F(x) = (x+3)
As per the given graph, the rational function that is graphed in the given image is option B: F(x) = x(x+3)(x-3) / (x-3)(x+3) as per the factors.
Based on the graph, we can see that the function has vertical asymptotes at x = -3 and x = 3.
Option A has only one factor of (x+3) and one factor of (x-3), so it would have only one vertical asymptote at x = 3 or x = -3, but not both.
Option B has two factors of (x-3) and two factors of (x+3), so it has two vertical asymptotes at x = 3 and x = -3, which matches the graph.
Option C has only one factor of (x-3) and no factor of (x+3), so it would have only one vertical asymptote at x = 3 or x = -3, but not both.
Option D has only one factor of (x+3) and no factor of (x-3), so it would have only one vertical asymptote at x = -3 or x = 3, but not both.
Therefore, the rational function that is graphed in the given image is option B: F(x) = x(x+3)(x-3) / (x-3)(x+3).

Find the final amount of money in an account if $7, 300 is deposited at 2% interest compounded semi annually and the money is left for 7 years
The final amount of money in the account after 7 years would be $8,790.56.
To calculate the final amount of money in an account, we can use the formula for compound interest:
A = [tex]P(1 + r/n)^{(nt)[/tex]
where A is the final amount of money, P is the initial amount of money, r is the annual interest rate, n is the number of times the interest is compounded per year, and t is the number of years.
In this case, we have P = $7,300, r = 0.02 (since the interest rate is 2%), n = 2 (since the interest is compounded semi-annually), and t = 7 (since the money is left for 7 years). Plugging these values into the formula, we get:
A = $7,300(1 + 0.02/2)¹⁴
A = $7,300(1.01)¹⁴
A = $8,790.56
This means that the initial investment of $7,300 earned $1,490.56 in interest over the 7-year period due to the compounding effect of the semi-annual interest payments.

You are on a fishing boat that leaves its pier and heads east. After traveling for 29 miles, there is a report warning of rough seas directly south. The captain turns the boat and follows a bearing of S35°W for 14.6 miles.
a. At this time, how far are you from the boat's pier?
b. What bearing could the boat have originally taken to arrive at this spot?
a. The boat is currently 60.5 miles from its pier.
b. The boat could have originally taken a bearing of either N45°E or S45°W to arrive at the current spot.
a.How to determine the distance from the boat's pier?
To determine the distance from the boat's pier, we can use the Pythagorean theorem since we have a right triangle formed by the boat's original position, the current position, and the distance traveled to reach the current position.
Let's call the distance from the boat's pier to the current position "d", and let's call the distance traveled after the turn "x".
Using trigonometry, we can see that:
sin(35°) = x/d
Rearranging this equation, we get:
x = d×sin(35°)
Now we can use the Pythagorean theorem to solve for "d":
d² = 29²+ (d×sin(35°))²
d² = 841 + 0.77d²
0.23d² = 841
d² = 3661.74
d = 60.5 miles (rounded to one decimal place)
Therefore, the boat is currently 60.5 miles from its pier.
b. How to determine the original bearing?
To determine the original bearing, we can use trigonometry again. Let's call the original bearing "θ". Then we have,
cos(θ) = 29/d
Rearranging this equation,
d = 29/cos(θ)
Now we can substitute this expression for "d" into the equation we used to solve for "x" earlier:
x = d×sin(35°)
x = (29/cos(θ))×sin(35°)
We know that after traveling this distance, the boat is currently 14.6 miles away from its original position. So we can set up another equation:
cos(θ) = 14.6/(29/cos(θ))
Simplifying, we get:
cos²(θ) = 0.5
Taking the inverse cosine of both sides,
θ = 45° or θ = 315°
Therefore, the boat could have originally taken a bearing of either N45°E or S45°W to arrive at the current spot.
