Answer: $624.24.
Step-by-step explanation:
To find the total amount of interest paid on the loan, we first need to find the total amount of money repaid over the course of 36 months.
The total amount repaid is the monthly payment multiplied by the number of months:
Total amount repaid = Monthly payment x Number of months
Total amount repaid = $79.84 x 36 = $2,874.24
To find the total amount of interest paid, we need to subtract the original amount borrowed from the total amount repaid:
Total interest paid = Total amount repaid - Original amount borrowed
Total interest paid = $2,874.24 - $2,250 = $624.24
Therefore, the total amount of interest paid on the loan is $624.24.
a. (10 points) The number of brownies sold by a bakery on a random day is a random variable with a mean value of 38 and a standard deviation of 6. What is the probability that the total number of brownies sold for a random sample of 56 days is less than 2070? Explain. b. (10 Points) Let X₁, X2, X3, and X4 represent the weight of shipment packages at a certain shipment facility. Suppose they are independent normal random variables with means µ4 7.4 pounds and μ₁ = 3.6, μ₂ = 0.9, µ3 = 1.8, μ4 µ2 variances o² = 0 = 0 = 0 = 1. Find P (2X₁ + 1X₂ + 3X3 + 1X4 ≤ 17.6). -
a. The probability that the total number of brownies sold for a random sample of 56 days is less than 2070 is approximately 0.0107.
b. The probability that 2X₁ + X₂ + 3X₃ + X₄ is less than or equal to 17.6
Explain probability
Probability is the measure of the likelihood or chance of an event occurring. It is expressed as a number between 0 and 1, where 0 means the event will not occur, and 1 means the event will definitely occur. Probability is a fundamental concept in mathematics and is used in many fields, including statistics, science, and finance.
According to the given information
a. The total number of brownies sold for a random sample of 56 days, Y, is a normal random variable with mean µ_Y = 56µ_X = 5638 = 2128 and standard deviation σ_Y = √(56)*σ_X = √(56)*6 = 25.21.
We want to find P(Y < 2070). Standardizing Y, we get:
Z = (Y - µ_Y) / σ_Y = (2070 - 2128) / 25.21 = -2.31
Using a standard normal distribution table or calculator, we can find that P(Z < -2.31) is approximately 0.0107. Therefore, the probability that the total number of brownies sold for a random sample of 56 days is less than 2070 is approximately 0.0107.
b. 2X₁ + X₂ + 3X₃ + X₄ is also a normal random variable with mean 2µ₁ + µ₂ + 3µ₃ + µ₄ = 2(3.6) + 0.9 + 3(1.8) + 7.4 = 18.5 and variance 4o² + o² + 9o² + o² = 14o².
We want to find P(2X₁ + X₂ + 3X₃ + X₄ ≤ 17.6). Standardizing the variable, we get:
Z = (17.6 - 18.5) / √(14o²) = -0.5735 / √(o²)
To find P(Z ≤ -0.5735 / √(o²)), we need to know the value of o². If o² = 1, then P(Z ≤ -0.5735) = 0.2831. If o² is a different value, we would need to adjust accordingly.
Therefore, the probability that 2X₁ + X₂ + 3X₃ + X₄ is less than or equal to 17.6

14. The local credit union is offering a special student checking account. The monthly cost of the account is $15. The first 10 checks are free, and each additional check costs $0.75. You search
the Internet and find a bank that offers a student checking account with no monthly charge. The first 10 checks are free, but each additional check costs $2.50.
a. Assume that you will be writing more than 10 checks a month. Let n represent the number of checks written in a month. Write a function rule for the cost c of each account in terms of n.
b. Write an inequality to determine what number of checks in the bank account would be more expensive than the credit union account.
c. Solve the inequality in part b.
Answer: a. c(n) = 15 + 0.75(n - 10)
b. 15 + 0.75(n - 10) = 2.50(n - 10)=
Simplifying and solving for n, we get:
n = 50
c. n > 50
Step-by-step explanation:
a. The cost c of the credit union account in terms of the number of checks written n can be expressed as:
c(n) = 15 + 0.75(n - 10)
The first term, 15, represents the monthly cost of the account, and the second term represents the additional cost per check beyond the first 10 free checks.
The cost c of the bank account in terms of the number of checks written n can be expressed as:
c(n) = 2.50(n - 10)
The first term, 0, represents the monthly cost of the account, and the second term represents the additional cost per check beyond the first 10 free checks.
b. We want to find the number of checks for which the bank account is more expensive than the credit union account. Let x be the number of checks that makes the cost of the two accounts equal. Then we have:
15 + 0.75(n - 10) = 2.50(n - 10)
Simplifying and solving for n, we get:
n = 50
So if the number of checks written in a month is greater than 50, the bank account will be more expensive than the credit union account.
c. The solution to the inequality is:
n > 50
This means that the number of checks written in a month must be greater than 50 for the bank account to be more expensive than the credit union account.
Suppose a supermarket ordered 13 cases of organic vegetable soup with a list price of $18.90 per case and 4 cases of organic baked beans with a list price of $33.50 per case. The wholesaler offered the supermarket a 39% trade discount. (Round your answers to the nearest cent.)
What is the total net amount (in $) the supermarket owes the wholesaler for the order?
The total net amount the supermarket owes the wholesaler for the order is $231.31.
What does discount mean?A discount is a reduction in the price of a product or service. It is often offered by businesses to encourage customers to buy more or to make a purchase they might not otherwise make. A discount can be expressed as a percentage or a specific dollar amount, and it is usually subtracted from the original price of the item or service.
According to the given informationTo find the total net amount the supermarket owes the wholesaler for the order, we need to first calculate the cost of each case of soup and baked beans after the 39% trade discount is applied, and then multiply those costs by the number of cases ordered.
The trade discount rate is 39%, which means the supermarket will receive a discount of 39% off the list price of each case of soup and baked beans. To calculate the cost of each case after the discount is applied, we can use the following formula:
Discounted cost = List price - (Discount rate x List price)
For the soup, the discounted cost per case is:
$18.90 - (0.39 x $18.90) = $11.51
For the baked beans, the discounted cost per case is:
$33.50 - (0.39 x $33.50) = $20.42
Now we can calculate the total net amount owed by the supermarket to the wholesaler:
Total net amount = (Number of cases of soup x Cost per case) + (Number of cases of baked beans x Cost per case)
Total net amount = (13 x $11.51) + (4 x $20.42)
Total net amount = $149.63 + $81.68
Total net amount = $231.31
Therefore, the total net amount the supermarket owes the wholesaler for the order is $231.31.

Charlie invests $325 in an account that pays 8% simple interest for 15 years.
Use the simple interest formula, I = P ∙ r ∙ t, to answer the following questions.
How much interest will Charlie’s initial investment earn over the 15-year period?
How much money does Charlie have after the 15 years?
Answer: To answer these questions using the simple interest formula, we need to know the values of P (the principal or initial investment), r (the interest rate), and t (the time period in years).
In this case, P = $325, r = 0.08 (8% expressed as a decimal), and t = 15.
Using the simple interest formula, I = P ∙ r ∙ t, we can calculate:
I = $325 ∙ 0.08 ∙ 15 = $390
Therefore, Charlie's initial investment will earn $390 in interest over the 15-year period.
To calculate how much money Charlie will have after the 15 years, we need to add the interest earned to the initial investment.
The total amount of money that Charlie will have after the 15 years is:
Total amount = Initial investment + Interest earned
Total amount = $325 + $390
Total amount = $715
Therefore, Charlie will have $715 after 15 years.

what is distributive property ?
The distributive property is a mathematical property that is used to simplify expressions that involve multiplication and addition or subtraction. It states that when you multiply a number (or variable) by a sum or difference,
In the given question,
To solve the equation 3(x+6) = x + 8 + x, you can use the distributive property of multiplication over addition to simplify the left-hand side of the equation, and then combine like terms on both sides of the equation.
Here are the steps:
Distribute the 3 on the left-hand side of the equation:
3(x+6) = 3x + 18
Combine the two x terms on the right-hand side of the equation:
3x + 18 = 2x + 8
Subtract 2x from both sides of the equation:
3x - 2x + 18 = 2x - 2x + 8
Simplifying this expression gives:
x + 18 = 8
Finally, subtract 18 from both sides of the equation:
x + 18 - 18 = 8 - 18
Simplifying this expression gives:
x = -10
Therefore, the solution to the equation 3(x+6) = x + 8 + x is x = -10.

From a group of 10 people, you randomly select 3 of them.
What is the probability that they are the 3 oldest people in the group?
Give your answer as a fraction
The probability of selecting the 3 oldest people in a group of 10 people is approximately 0.0083 or 0.83%.
What is fraction?
A fraction is a method of representing a part of a whole or a ratio of two numbers. It is a number that is written in the form of one integer (the numerator) over another integer (the denominator), separated by a line or slash.
The probability of selecting the 3 oldest people in a group of 10 people depends on the assumption that all 10 people are distinct individuals and that the selection process is truly random.
The total number of ways to select 3 people from a group of 10 people is given by the combination formula:
C(10, 3) = 10! / (3! * 7!) = 120
This means that there are 120 possible ways to select a group of 3 people from a group of 10 people.
Since we are interested in selecting the 3 oldest people, we assume that the 3 oldest people are identified and we only need to select them from the group of 10 people. There is only 1 way to select the 3 oldest people out of the group of 10 people.
Therefore, the probability of selecting the 3 oldest people in a group of 10 people is:
P = Number of ways to select the 3 oldest people / Total number of ways to select 3 people from a group of 10 people
P = 1 / 120
P = 0.0083
So, the probability of selecting the 3 oldest people in a group of 10 people is approximately 0.0083 or 0.83%.

How long will take the T-shirt to reach its maximum height? What is the maximum height? What is the range of the function that models the height of the T-shirt over time?
2. During halftime of a football game, a sing shot launches T-shirts at the crowd
A T-shirt is launched from a height of 3 feet with an intal upward velocity of 80 feet per second
The T-shirt is caught 36 feet above the field
How long will take the T-shirt to reach its maximum height? What is the maximum height? What is the range of the function that models the height of the T-shirt over time?
Answer:
1. Using the kinematic equation h(t) = -16t^2 + v0t + h0, where h0 is the initial height, v0 is the initial velocity, and t is time, we have:
h(t) = -16t^2 + 72t + 4
To find the maximum height, we need to find the vertex of the parabolic function h(t). The t-coordinate of the vertex is given by t = -b/2a, where a = -16 and b = 72:
t = -b/2a = -72/(2(-16)) = 2.25 seconds
To find the maximum height, we substitute t = 2.25 seconds into the equation for h(t):
h(2.25) = -16(2.25)^2 + 72(2.25) + 4 = 82 feet
The range of the function h(t) is [4, 82], since the T-shirt starts at a height of 4 feet and reaches a maximum height of 82 feet before falling back to the ground.
2. Using the same kinematic equation as before, we have:
h(t) = -16t^2 + 80t + 3
To find the maximum height, we again need to find the vertex of the parabolic function h(t). The t-coordinate of the vertex is given by t = -b/2a, where a = -16 and b = 80:
t = -b/2a = -80/(2(-16)) = 2.5 seconds
To find the maximum height, we substitute t = 2.5 seconds into the equation for h(t):
h(2.5) = -16(2.5)^2 + 80(2.5) + 3 = 80 feet
The range of the function h(t) is [3, 80], since the T-shirt starts at a height of 3 feet and reaches a maximum height of 80 feet before falling back to the ground.

The table shows the age distribution of members of a gym.
Age - Under 21 21 -35 36 - 55 Over 55
percentage 12 42 32 14
a) To find the probability that the selected member is 21 or more,
Add the percentage of members who are 21-35, 36-55, and over 55 since all of these age groups are 21 or more.
Probability (21 or more)
= Percentage (21-35) + Percentage (36-55) + Percentage (Over 55)
= 42% + 32% + 14%
= 88%
b) To find the probability that the selected member is 55 or less,
Add the percentage of members who are under 21, 21-35, and 36-55 since all of these age groups are 55 or less.
Probability (55 or less)
= Percentage (Under 21) + Percentage (21-35) + Percentage (36-55)
= 12% + 42% + 32%
= 86%
c) To find the probability that the selected member is not in the 21 to 35 age group,
Add the percentage of members who are under 21, 36-55, and over 55 since all of these age groups are not in the 21 to 35 age group.
Probability (not in the 21 to 35 age group)
= Percentage (Under 21) + Percentage (36-55) + Percentage (Over 55)
= 12% + 32% + 14%
= 58%
Therefore,
The probability that the selected member is 21 or more is 88%.

In 2012, the population of a city was 5.51 million. The exponential growth rate was 3.82% per year.
a) Find the exponential growth function.
b) Estimate the population of the city in 2018.
c) When will the population of the city be 10 million?
d) Find the doubling time.
helppppppp
Answer:
a) To find the exponential growth function, we can use the formula:
P(t) = P0 * e^(rt)
Where:
P(t) = the population at time t
P0 = the initial population (in this case, 5.51 million)
e = the mathematical constant e (approximately 2.71828)
r = the annual growth rate (in decimal form)
t = the number of years
Substituting the given values, we have:
P(t) = 5.51 * e^(0.0382t)
b) To estimate the population of the city in 2018, we can substitute t = 6 (since 2018 is 6 years after 2012) into the exponential growth function:
P(6) = 5.51 * e^(0.0382*6) ≈ 6.93 million
Therefore, the estimated population of the city in 2018 is approximately 6.93 million.
c) To find when the population of the city will be 10 million, we can set P(t) = 10 and solve for t:
10 = 5.51 * e^(0.0382t)
e^(0.0382t) = 10/5.51
0.0382t = ln(10/5.51)
t ≈ 11.7 years
Therefore, the population of the city will be 10 million in approximately 11.7 years from 2012, or around the year 2023.
d) To find the doubling time, we can use the formula:
T = ln(2) / r
Where:
T = the doubling time
ln = the natural logarithm
2 = the factor by which the population grows (i.e., doubling)
r = the annual growth rate (in decimal form)
Substituting the given value of r, we have:
T = ln(2) / 0.0382 ≈ 18.1 years
Therefore, the doubling time for the population of the city is approximately 18.1 years.
A solid glass cylinder is 31 centimeters high and has a diameter of 3 centimeters. What is the mass of the cylinder if the density of glass is 1.6 grams per cubic centimeter?
Answer:
the mass of the solid glass cylinder is approximately 350.67 grams.
Step-by-step explanation:
The diameter of the cylinder is 3 centimeters, which means that its radius is 1.5 centimeters (half the diameter). The area of the base of the cylinder is the area of a circle, calculated as pi (π) multiplied by the radius squared:
Base area = π x radius^2
Base area = π x (1.5 cm)^2
Base area = 7.07 cm^2 (approximately)
The volume of the cylinder is calculated by multiplying the area of the base by the height:
Cylinder Volume = Base Area x Height
Cylinder volume = 7.07 cm^2 x 31 cm
Cylinder volume = 219.17 cm^3 (approximately)
Now that we know the volume of the cylinder, we can calculate its mass using the density of the glass:
Mass = Density x Volume
Mass = 1.6 g/cm^3 x 219.17 cm^3
Mass = 350.67 grams (approximately)
Problem 6: Find the surface area and round to the nearest tenth.
Therefore, the surface area of the prism is approximately 557.2 square feet when rounded to the nearest tenth.
What is surface area of prism?The surface area of a prism is the total area of all its faces, including the bases. The formula for finding the surface area of a prism depends on the shape of its base. For a right prism, the surface area can be found by adding the area of the two bases to the lateral area, which is the sum of the areas of all the rectangular faces of the prism.
Here,
To find the surface area of the prism, we need to find the area of each of the six rectangular faces that make up the prism, and then add them together. The two triangular faces are congruent, so we can find the area of one and double it to get the total area of the two.
The area of a triangle is given by:
Area = (1/2) x base x height
For the given triangles, the base is 9 ft and the height is 8 ft (for one triangle) and 10 ft (for the other triangle), so the areas are:
Area1 = (1/2) x 9 ft x 8 ft
= 36 ft²
Area2 = (1/2) x 9 ft x 10 ft
= 45 ft²
The total area of the two triangles is:
TotalArea = 2 x (Area1 + Area2)
= 2 x (36 ft² + 45 ft²)
= 162 ft²
Now, we need to find the area of the four rectangular faces. Each face is a rectangle with a length of 13 ft and a height of 7.6 ft, so the area of each face is:
AreaRect = length x height
= 13 ft x 7.6 ft
= 98.8 ft²
The total area of the four rectangular faces is:
TotalRectArea = 4 x AreaRect
= 4 x 98.8 ft²
= 395.2 ft²
To find the total surface area of the prism, we add the area of the two triangles to the area of the four rectangular faces:
TotalSA = TotalRectArea + TotalArea
= 395.2 ft² + 162 ft²
= 557.2 ft²
