The following table shows the number of candy bars bought at a local grocery store and the
total cost of the candy bars:
Candy Bars: 3, 5, 8, 12, 15, 20, 25
Total Cost: $6.65, $10.45, $16.15, $23.75, $29.45, $38.95, $48.45
If B represents the number of candy bars purchased and C represents the total cost of the candy bars, write the linear model that models the cost of any number of candy bars.
Answers
The linear model that represents the cost of any number of candy bars can be written as: C = $1.90B + $0.95
To write the linear model that models the cost of any number of candy bars, we need to find the equation of a line that best fits the given data points. We'll use the variables B for the number of candy bars purchased and C for the total cost of the candy bars.
Looking at the given data, we can see that there is a linear relationship between the number of candy bars and the total cost. As the number of candy bars increases, the total cost also increases.
To find the equation of the line, we need to determine the slope and the y-intercept. We can use the formula for the equation of a line: y = mx + b, where m is the slope and b is the y-intercept.
First, let's find the slope (m) using two points from the given data, for example, (3, $6.65) and (25, $48.45):
m = (C2 - C1) / (B2 - B1)
= ($48.45 - $6.65) / (25 - 3)
= $41.80 / 22
≈ $1.90
Now, let's find the y-intercept (b) using one of the data points, for example, (3, $6.65):
b = C - mB
= $6.65 - ($1.90 * 3)
= $6.65 - $5.70
≈ $0.95
Therefore, the linear model that represents the cost of any number of candy bars can be written as:
C = $1.90B + $0.95
This equation represents a linear relationship between the number of candy bars (B) and the total cost (C). For any given value of B, you can substitute it into the equation to find the corresponding estimated total cost of the candy bars.

Use the Buying a Car information above to answer this question. What is your monthly payment if you choose 0% financing for 48 months? Round to the nearest dollar. Use the Buying a Car information above to answer this question. The rebate offer is $2900, and you can obtain a car loan at your local bank for the balance at 5.24% compounded monthly for 48 months. If you choose the rebate, what is your monthly payment? $ Round to the nearest dollar.
Answers
If you choose the rebate offer, your monthly payment for the car loan at the bank will be approximately $557 (rounded to the nearest dollar).
To calculate the monthly payment for each financing option, we'll use the information provided:
1. 0% financing for 48 months:
Since the financing is offered at 0% interest, the monthly payment can be calculated by dividing the total purchase price by the number of months.
Purchase Price: $26,050
Number of Months: 48
Monthly Payment = Purchase Price / Number of Months
Monthly Payment = $26,050 / 48 ≈ $543
Therefore, the monthly payment for the 0% financing option for 48 months is approximately $543.
2. Rebate offer and car loan at the bank:
If you choose the rebate offer, you'll need to finance the remaining balance after deducting the rebate amount. Let's calculate the remaining balance:
Purchase Price: $26,050
Rebate Offer: $2,900
Remaining Balance = Purchase Price - Rebate Offer
Remaining Balance = $26,050 - $2,900 = $23,150
Now, we'll calculate the monthly payment using the remaining balance and the loan terms from the local bank:
Remaining Balance: $23,150
Interest Rate: 5.24% (compounded monthly)
Number of Months: 48
Monthly Payment = (Remaining Balance * Monthly Interest Rate) / (1 - (1 + Monthly Interest Rate)^(-Number of Months))
First, let's calculate the Monthly Interest Rate:
Monthly Interest Rate = Annual Interest Rate / 12
Monthly Interest Rate = 5.24% / 12 ≈ 0.437%
Now, we can calculate the Monthly Payment using the formula mentioned above:
Monthly Payment = ($23,150 * 0.437%) / (1 - (1 + 0.437%)^(-48))
Monthly Payment ≈ $557
Therefore, if you choose the rebate offer, your monthly payment for the car loan at the bank will be approximately $557 (rounded to the nearest dollar).

Answers
The major branch of statistics that deals with making inferences about a population based on a sample is called inferential statistics.
In this scenario, you collected data from a sample of eight classmates and calculated the average score to be 65.
Based on this sample, you made an inference about the entire class, stating that the average test score for the whole class was less than 70. This inference is an example of using inferential statistics. Inferential statistics allows us to draw conclusions and make predictions about a larger population based on a smaller sample.
By using statistical techniques and assumptions, we can estimate parameters, such as the population mean, using sample statistics. This helps us make informed decisions and generalizations about a population when it is not feasible or practical to collect data from the entire population.

Answers
The total cost of seeds to cover the total area is $110 and the total cost of fencing the park is $13914.
Given that, a gardener is reseeding a city park that has the shape of a right triangle with a base of 150 feet and a height of 200 feet. The third side of the park is 250 feet long.
What is the formula to find the area of a triangle?The formula to find the area of a triangle is Area of triangle = 1/2 ×base × height.
Now, A= 1/2 × 150×200
A= 15000 sq. ft
a) 1 bag of grass seed covers 3750 sq. ft
So, 15000/3750 = 4 bags
The cost of 1 bag = $27.50
4 bags = 4×27.50= $110
b) Wire fencing costs $23.19 for every 50 ft roll
Then, Perimeter P = sum of all sides = 150+200+250=600 feet
The cost of fencing 50 ft = $23.19
So, 600 ft = 600×23.19
Fencing cost of wire =$13914
c) Fence posts cost $3.19 each and need to be placed every 5 ft.
We need to find out how many posts are needed and what is the cost altogether.
Now, Perimeter = 600 feet
Posts are kept 5 ft apart
Thus, 600/5= 120 posts
Cost of 1 post = $3.19
Now, 120 posts = 119×3.19= $379.61
Therefore, the total cost of seeds to cover the total area is $110 and the total cost of fencing the park is $13914.

What is the surface area for a rectangular prism with the height of 6 inches, width of 8 inches, and the length of 4 inches
Answers
Answer:
Using the formula, we can find that the surface area is 208 in².
Step-by-step explanation:
To find the surface area (SA) for a rectangular prism, substitute its dimensions into the formula and solve.
DimensionsDimensions mean the side lengths of the shape, the height, width and length. We know the dimensions from the question.
Height: h = 6 in
Width: w = 8 in
Length: l = 4 in
FormulaWe will need the formula to find the surface area for rectangular prisms. Note that different shapes have a different formula for finding surface area.
\(SA= 2(lw + lh + hw)\)
Substitute the dimensions h = 6in, w = 8in and l = 4in into the formula.
\(SA= 2((4\ in)(8\ in) + (4\ in)(6\ in) + (6\ in)(8\ in))\)
Remember order of operations (BEDMAS) when solving. Multiply within the brackets first.
\(SA= 2(32\ in^{2} + 24\ in^{2} + 48\ in^{2})\) Add within the brackets.
\(SA= 2(104\ in^{2})\) Multiply.
\(SA= 208\ in^{2}\) Final answer
Tip: The final answer for area will always have squared units.
∴ The surface area (SA) of the rectangular prism with a height of 6 inches, width of 8 inches, and length of 4 inches is 208 squared inches.
angles w and x are complementary. determine the degree measure of ∠w if m∠x = 29.8°. 55.1° 60.2° 90° 150.2°
Answers
Answer:
measure of ∠w = 60.2 °
Step-by-step explanation:
When two angles are complementary, they form a right angle. Thus, the sum of their measures, m, equals 90°.Because we're told that m∠x = 29.8°, we can find m∠w in ° by subtracting 29.8 from 90.
m∠x + m∠w = 90
m∠w = 90 - m∠x
m∠w = 90 - 29.8
m∠w = 60.2

You are required to determine the confidence interval for the mean duration of a child using training wheels based on a sample of 14 kids in this problem. Since the sample size is small (less than 30) and we don't know the population standard deviation, we can use the t-distribution. The sample mean is plus or minus the t-value times, and the standard error is the formula for the confidence interval. Since the confidence level is specified as 95%, we must determine the t-value with 13 degrees of freedom that represent a 95% confidence level. To determine this value, we can use a t-table or a calculator, and we can then enter it into the formula to determine the confidence interval.

Hi! I know this is not the correct way to ask a question, but may someone explain how to do the Division Property of Equality and the Multiplication Property of Equality?
Answers
Answer:
Step-by-step explanation:
So the division property states that if both sides of an equation are equal and whenever you divide both sides of that equation by the same number they should stay equal. Example
12=12 right? so if I divide both 12 and 12 by 3 I should get 3=3
We use this to solve for variable such as x
So new example lets take
5x=25
Since both sides are equal I can divide by the same number and should get an equal number right? So lets divide by 5 on both sides. 5x divided by 5 equals x and 25 divided by 5 equals 5 so my new equation is
x equals 5 or x=5.
If I plug my x=5 back into the equation they should be equal so lets see...
5(5)=25
25=25

Given that f(x)=xcosx,0 ≤ x ≤ 5. a) Find the minimum of the function f in the specified range and correspoeting x
b) Find the maxımum of the function f in the specified range and corresponding x :
Answers
a) The minimum value of the function f(x) = xcos(x) in the range 0 ≤ x ≤ 5 is approximately -4.92, and it occurs at x ≈ 3.38.
b) The maximum value of the function f(x) = xcos(x) in the range 0 ≤ x ≤ 5 is approximately 4.92, and it occurs at x ≈ 1.57 and x ≈ 4.71.
To find the minimum and maximum values of the function f(x) = xcos(x) in the specified range, we need to evaluate the function at critical points and endpoints.
a) To find the minimum, we look for the critical points where the derivative of f(x) is equal to zero. Taking the derivative of f(x) with respect to x, we get f'(x) = cos(x) - xsin(x). Solving cos(x) - xsin(x) = 0 is not straightforward, but we can use numerical methods or a graphing calculator to find that the minimum value of f(x) in the range 0 ≤ x ≤ 5 is approximately -4.92, and it occurs at x ≈ 3.38.
b) To find the maximum, we also look for critical points and evaluate f(x) at the endpoints of the range. The critical points are the same as in part a, and we can find that f(0) ≈ 0, f(5) ≈ 4.92, and f(1.57) ≈ f(4.71) ≈ 4.92. Thus, the maximum value of f(x) in the range 0 ≤ x ≤ 5 is approximately 4.92, and it occurs at x ≈ 1.57 and x ≈ 4.71.
