1. Calculate the amount of sales tax:

  - The item costs $350 before tax.

  - The sales tax rate is 14%.

  - To find the sales tax amount, multiply the cost of the item by the tax rate:

    Sales tax = $350 * 0.14 = $49.

2. Determine the total cost of the item including tax:

  - Add the sales tax amount to the original cost of the item:

    Total cost = $350 + $49 = $399.

3. Analyze the spinner results:

  - The spinner has 10 equal-sized slices.

  - There are 4 yellow slices, 3 red slices, and 3 blue slices.

  - Kala spun the dial 1000 times.

Answer:

Explanation:

a) Here, we want to use the vertical line test to check if y is a function of x

To use the test, we draw a vertical line through any point on the graph. If the vertical line touches two points on the curve, then y is not a function of x

If we draw a vertical line as described, we would see that it touches two points on the curve which indicates that y is not a function of x

b) To solve for y, we proceed with the following steps:

A²+B²= C²

31²+ 21²= z²

961+441 = z²

1402= z²

z= 37.443290454

The estimated sample mean for profit as a percentage of assets is approximately 17.970, the estimated sample variance is approximately 24.437, and the estimated sample standard deviation is approximately 4.943.

To estimate the sample mean, sample variance, and sample standard deviation for profit as a percentage of assets based on the given information, we can calculate the respective measures using the midpoint of each interval and the number of companies in each interval.

First, let's calculate the midpoint for each interval:

Midpoint of 8.6-12.5:= 10.55

Midpoint of 12.6-16.5:  = 14.55

Midpoint of 16.6-20.5:  = 18.55

Midpoint of 20.6-24.5:  = 22.55

Midpoint of 24.6-28.5:  = 26.55

Next, let's calculate the estimated sample mean:

Sample Mean = (Midpoint1 * Frequency1 + Midpoint2 * Frequency2 + Midpoint3 * Frequency3 + Midpoint4 * Frequency4 + Midpoint5 * Frequency5) / (Total Frequency)

Sample Mean = (10.55 * 13 + 14.55 * 18 + 18.55 * 7 + 22.55 * 5 + 26.55 * 7) / 50

Sample Mean ≈ 17.970

To estimate the sample variance, we'll use the formula:

where X is the midpoint, X is the sample mean, and n is the total frequency.

Using this formula, we can calculate the estimated sample variance:

\(\frac{ [(13 * (10.55 - 17.970)^2 + 18 * (14.55 - 17.970)^2 + 7 * (18.55 - 17.970)^2 + 5 * (22.55 - 17.970)^2 + 7 * (26.55 - 17.970)^2)}{ (50 - 1)}\)

Sample Variance ≈ 24.437

Finally, we can estimate the sample standard deviation by taking the square root of the sample variance:

Sample Standard Deviation = √Sample Variance

Sample Standard Deviation ≈ √24.437 ≈ 4.943

a) The terminal point is 0.896 radius length.

b) The value returned is -0.896.

We have,

The circle's radius is 3 units long and the terminal point is located at (−2.69,−1.33)

a. Since the circle's radius is 3 units long, we divide the x-coordinate by 3:

x-coordinate of terminal point: -2.69

Number of radius lengths to the right: -2.69 / 3 ≈ -0.896

However, since the angle is measured from the 3-o'clock direction, we consider it to be in the clockwise direction.

Thus, the number of radius lengths to the right is

Number of radius lengths to the right: -(-0.896) = 0.896

Therefore, the terminal point is 0.896 radius length.

b. Using Trigonometry

cos(h) = x-coordinate of terminal point / radius length

cos(h) = -2.69 / 3 ≈ -0.896

c. As, θ = h. From the given information, we have:

θ ≈ -0.896 radians

(a). The Tanakas paid a total of $523,906.40 for the townhome.

(b). The Tanakas paid $206,906.40 in interest on their mortgage over the 15-year period.

Simple interest is the type of interest that is calculated on the principal amount only.

It is a fixed percentage of the principal amount that is charged or earned over a certain period of time, without any compounding of interest.

(a) The total amount they ended up paying for the townhome is the sum of the down payment and the total amount of the mortgage payments.

Down payment = $41,000

Total amount of mortgage payments = monthly payment x number of payments = $2675.04 x 12 months/year x 15 years = $482,906.40

Total amount paid = down payment + total amount of mortgage payments = $41,000 + $482,906.40 = $523,906.40

(b) The amount of interest paid on the mortgage can be calculated by subtracting the principal (the amount borrowed) from the total amount paid.

Principal = Total cost of townhome - Down payment = $358,000 - $41,000 = $317,000

Total interest paid = Total amount paid - Principal = $523,906.40 - $317,000 = $206,906.40

The mean should be calculated for data sets A, B, C, and D.

It is useful to take into account the nature of the data and any potential outliers when deciding whether to choose the mean or the median as the measure of center in a data set.

When the data is symmetrically distributed with no major outliers, the mean is usually a better choice. It affects extreme values and gives an indication of the average value.

The median, on the other hand, is often preferred when the data is skewed or contains outliers. It represents the middle value when the data is ordered, and it is less affected by extreme values.

Answer:

Just put this in your calculator I've shown you how to do the conversion

Answer:

Step-by-step explanation:

a) The formula for the regression function is:

Maintenance Cost = 54.7757 + 120.689 x Age of Car

b) The slope of the regression equation is 120.689. This means that on average, for every one year increase in the age of a car, the maintenance cost is expected to increase by $120.689.

c) To construct a 95% interval to predict the maintenance cost for a car that is 7 years old, we can use the formula:

Y = a + bX ± tα/2 * SE

where Y is the predicted maintenance cost, a is the intercept, b is the slope, X is the age of the car, tα/2 is the t-value for the 95% confidence level with n-2 degrees of freedom (11 in this case), and SE is the standard error of the estimate.

Plugging in the values, we get:

Y = 54.7757 + 120.689 * 7 ± 2.201 * 11.8442

Y = 923.167 ± 26.010

Therefore, we can be 95% confident that the maintenance cost for a car that is 7 years old will be between $897.16 and $949.17.

d) The null hypothesis is that there is no significant linear relationship between the average maintenance cost and the age of a car in years. The alternative hypothesis is that there is a significant linear relationship between the average maintenance cost and the age of a car in years.

To test the hypothesis, we can perform a t-test on the slope coefficient using the t-statistic and the p-value provided in the output. The t-statistic is 10.1898, which is much greater than the critical t-value at the 0.05 level of significance for a two-tailed test with 11 degrees of freedom (2.201). The p-value is 0.0000, which is less than the significance level of 0.05. Therefore, we can reject the null hypothesis and conclude that there is a significant linear relationship between the maintenance cost and the age of the car in years.

Answer:

The equation that models the relationship between Z and N is N = 56 Z

Step-by-step explanation:

The form of the linear equation is y = m x + b, where

∵ Mark reads 42 pages of a book every \(\frac{3}{4}\) of an hour

→ Find his rate per hour by dividing the number of pages by its time

∴ His rate of reading = 42 ÷  \(\frac{3}{4}\) = 42 ×  \(\frac{4}{3}\) = 56 pages per hour

∵ His rate = 56 pages/hour

∴ m = 56

∵ Z represents the number of hours Mark reads

→ That means replace x in the form of the equation above with Z

∵ N represents the number of pages of the book he reads

→ That means replace y in the form of the equation above with N

∴ N = 56 Z + b

∵ There is no initial amount of reading

∴ b = 0

∴ N = 56 Z

The equation that models the relationship between Z and N is N = 56 Z
