Draw a coordinate plane. Plot the points: A(3, 4), B(2, 2), C(5, 8), D(7, 12), and E(9, 14). All but one of the points are on the same line. Which one is not?

Answer: (7, 1)

Step-by-step explanation:

To find the coordinates of Q' which is the image of point Q(0, 6) under the translation (x, y) → (x + 7, y − 5), we can apply the translation to the coordinates of Q as follows:

x-coordinate of Q' = x-coordinate of Q + 7

= 0 + 7

= 7

y-coordinate of Q' = y-coordinate of Q - 5

= 6 - 5

= 1

Therefore, the coordinates of Q' are (7, 1).

the cost per mile over the course of a year for a $24,000 car that depreciates 20%, with costs shown in the table, and that has been driven for 10,000 miles is $0.59 per mile. Answer B is correct.

To calculate the cost per mile, we need to add up all the expenses for the car and divide by the total miles driven.

First, we need to calculate the total depreciation for the car:

Depreciation = 20% * $24,000 = $4,800

Next, we can calculate the total expenses for the car:

Total expenses = Gas + Insurance + Oil + Registration + Depreciation

Total expenses = $550 + $400 + $90 + $100 + $4,800

Total expenses = $5,940

Finally, we can calculate the cost per mile:

Cost per mile = Total expenses / Miles driven

Cost per mile = $5,940 / 10,000

Cost per mile = $0.594 or $0.59 (rounded to the nearest cent)

Therefore, the cost per mile over the course of a year for a $24,000 car that depreciates 20%, with costs shown in the table, and that has been driven for 10,000 miles is $0.59 per mile. Answer B is correct.

Note: Option D is not a possible answer because the cost per mile cannot be greater than the total expenses divided by the miles driven, which in this case is $0.594.

The amount of interest that is earned on Sandra's card after 1 year if Sandra makes no payment is: $538.48.

We can obtain the right answer by using using the formula for compound interest as follows: A = P(1 + r/n)^(nt)

where:

P = $2,500

r = 0.1999 (since the APR is 19.99%)

n = 4 (since the interest compounds quarterly)

t = 1 (since we're looking at the interest earned after 1 year)

Substituting these values into the formula, we get:

A = $2,500(1 + 0.1999/4)^(4*1)

A = $2,500(1.049975)^4

A = $2,500(1.207789)

A = $3,019.47

So after 1 year, Sandra will owe $3,019.47 on her credit card. The interest earned is the difference between this amount and the initial amount charged, which is:

Interest = $3,019.47 - $2,500

For the given problem, The correct answer will be option 3: The median is the best measure of center, and it equals 19.

A box plot,also known as a box-and-whisker plot, is used for graphical representation of summary statistics from a data set. It helps by providing a visual representation of a data set's central tendency, dispersion, and skewness, making it straightforward to identify important data aspects.

As box ranges from (17 to 21), the interquartile range (IQR) is [tex](21 - 17 = 4)[/tex].

The median is represented by the line inside the box, which is at 19. This shows that 50% of whole data is less than 19 and 50% of it is greater than 19.

Outside the box, the lines finish at 10 and 27, representing the lower and upper whiskers, respectively. Data range is represented by these lines, where lower whisker extends to a minimum of 10 and the higher whisker reaching to a maximum upto 27.

Since the median represents the middle value of the data when sorted in ascending order, and it is not influenced by outliers or extreme values, it is considered a robust measure of center. In this case, the median is 19, as it is the value at the center of the data according to the box plot.

Answer: To determine whether the condition of equal standard deviations is met in this case, we can perform a quick check by comparing the sample standard deviations of each group. If the sample standard deviations are roughly equal, then we can assume that the condition of equal standard deviations is met.

Alternatively, we can use Levene's test for equality of variances, which tests the null hypothesis that the population variances are equal across all groups. If the p-value of the test is greater than the significance level (usually 0.05), then we can assume that the condition of equal standard deviations is met.

Without the data or the sample standard deviations, it is not possible to determine whether the condition of equal standard deviations is met in this case.

Step-by-step explanation:

The Standard Normal Table is a tool that is used to calculate probabilities associated with the standard normal distribution.

When using the Standard Normal Table, we can find the area to the left of z < -2.34 by first locating the value -2.3 in the left-hand column of the table and the value -0.04 in the top row of the table.

Then, we find the intersection of the row and column to locate the corresponding value of 0.0099. This value represents the area to the left of -2.3 on the standard normal distribution.

To find the area to the left of -2.34, we need to adjust the value by subtracting the area to the left of -2.34 from the area to the left of -2.3.

The standard normal distribution is symmetric around the mean of 0. It means the area to the right of -2.3 is the same as the area to the left of 2.3.

Therefore, the area to the left of z < -2.34 is the area to the left of -2.3 (0.0099) minus the area between -2.34 and -2.3 (0.0040), which equals 0.0059. So, the area to the left of z < -2.34 is 0.0059.

The two solutions to the system of equations are (x,y) = (7/5,-3) and (x,y) = (144/65,-12/13).

What is quadratic equation?

it's a second-degree quadratic equation which is an algebraic equation in x.

We can use substitution to solve this system of equations.

First, we solve the second equation for one of the variables, say x:

5x + 12y + 13 = 0

5x = -12y - 13

x = (-12/5)y - (13/5)

Next, we substitute this expression for x into the first equation:

x² + y² = 1

[(-12/5)y - (13/5)]² + y² = 1

Expanding the square and simplifying, we get:

y² + [(144/25)y² + (312/25)y + (169/25)] + y² = 1

(26/5)y² + (312/25)y + (144/25) = 0

Multiplying both sides by 25 to eliminate the fractions:

26y² + 312y + 144 = 0

Dividing by 4 to simplify:

6.5y² + 78y + 36 = 0

Using the quadratic formula:

y = (-b ± sqrt(b² - 4ac)) / 2a

where a = 6.5, b = 78, and c = 36.

Plugging in these values:

y = (-78 ± sqrt(78² - 4(6.5)(36))) / 2(6.5)

y = (-78 ± sqrt(4761)) / 13

y = (-78 ± 69) / 13

y = -3 or -12/13

If y = -3, then substituting into the equation for x gives:

x = (-12/5)(-3) - (13/5) = 7/5

So one solution is (x,y) = (7/5,-3).

If y = -12/13, then substituting into the equation for x gives:

x = (-12/5)(-12/13) - (13/5) = 144/65

So another solution is (x,y) = (144/65,-12/13).

Therefore, the two solutions to the system of equations are (x,y) = (7/5,-3) and (x,y) = (144/65,-12/13).

The margin of error is an important factor in determining the sample size needed to estimate a parameter, it is not the only factor - False.

Other factors that need to be considered include the level of confidence desired, the variability of the population being sampled, and the size of the population.

The margin of error is the amount of error that is acceptable in the estimate of the parameter. The smaller the margin of error desired, the larger the sample size needed.

A higher level of confidence requires a larger sample size, as there is less room for error in the estimate. The variability of the population being sampled also plays a role in determining the sample size needed.

Finally, the size of the population being sampled also affects the sample size needed.

A smaller population requires a smaller sample size, while a larger population requires a larger sample size to ensure a representative sample.

In geometry, an arc is a portion of the circumference of a circle or any other curved shape. It is defined by two endpoints and all the points on the curve between those endpoints. The measure of an arc is typically given in degrees, and it is equal to the measure of the central angle that subtends the arc.

Here,

Since P is the center of the circle, we know that arc KM is twice the measure of angle KPM. Therefore, we need to find angle KPM first.

We know that angle KPL is 100 degrees, so angle KPM is the supplement of angle KPL, which is:

Similarly, we know that angle NPM is 120 degrees, so angle NPL is the supplement of angle NPM, which is:

180 degrees - 120 degrees = 60 degrees

Since angle KPL and angle NPL are vertical angles, they are congruent. Therefore, angle KPL has a measure of 60 degrees.

what is  chord ?

In geometry, a chord is a line segment that connects two points on the circumference of a circle. It is the straight line that intersects a circle at two points. In other words, a chord is a line segment that lies entirely inside the circle and connects two points on the circle.

In the given question,

If we draw a diagram of the circle with diameter 170 inches, we can see that the chords of length 26 inches divide the circle into two regions. We are interested in finding the distance from each chord to the center of the circle.

To solve this problem, we can use the following formula:

distance from chord to center = 1/2 * √(4r² - c²)

where r is the radius of the circle and c is the length of the chord.

First, we need to find the radius of the circle. The radius is half of the diameter, so:

r = 1/2 * diameter = 1/2 * 170 = 85 inches

Next, we can use the formula above to find the distance from each chord to the center of the circle. Plugging in the values we have:

distance from chord to center = 1/2 * √(4r² - c²)

distance from chord to center = 1/2 * √(4(85)² - 26²)

distance from chord to center = 1/2 * √(28,900)

distance from chord to center = 1/2 * 170

distance from chord to center = 85
