The parallel line cannot have a y-intercept of c because then the lines would be :- The same line.

Parallel lines are two lines in the same plane that are equal distance apart and never intersect.

Two parallel lines have the same slope but different y-intercepts. If one of the parallel lines has a y-intercept of c, its equation is y = mx + c, where m is the slope. The other parallel line's equation would be y = mx + b, where b is a separate y-intercept.

If two lines have the same slope m and y-intercept c, their equations are the same: y = mx + c. As a result, they would be the same line rather than parallel lines.

The scatter plot that shows a negative nonlinear association is option C.

A scatter plot is a type of graph that displays the relationship between two variables. It is used to show how much one variable is affected by another variable. One variable is plotted on the horizontal axis (x-axis) and the other variable is plotted on the vertical axis (y-axis).

Here,

In this scatter plot, as the x-axis values increase, the y-axis values initially increase and then decrease. This type of association is referred to as a negative nonlinear association, where the direction of the association is negative (decreasing) and the shape of the association is nonlinear (not a straight line). The other options either show a positive association (increasing values of x and y) or a linear association (a straight line).

The average rate of change of each function on the interval 2 ≤ x ≤ 6 is given as follows:

The average rate of change of a function is given by the change in the output of the function divided by the change in the input of the function. Hence we must identify the change in the output, the change in the input, and then divide then to obtain the average rate of change.

For the function f(x), we have that:

Hence the rate is given as follows:

r = (2 - 7)/(6 - 2)

r = -5/4

r = -1.25.

For the function g(x), we have that:

Hence the rate is given as follows:

r = (-10.29 - (-7.43))/(6 - 2)

r = -0.715

The probability that Tara selects 1 pen and then 1 marker is 6/30 (option b).

To solve this problem, we need to first find the total number of ways that Tara can select two items from the box without replacement.

In this case, we have n = 6 (3 pens, 2 markers, and 1 highlighter) and r = 2. Therefore, the total number of ways that Tara can select two items is:

6C2 = 6! / 2! (6 - 2)! = 15

Next, we need to find the number of ways that Tara can select a pen first and then a marker.

Therefore, the number of ways to select a pen first is 3, and the number of ways to select a marker second is 2. The total number of ways to select a pen first and then a marker is:

3 x 2 = 6

Finally, we can find the probability of selecting a pen first and then a marker by dividing the number of ways to select a pen first and then a marker by the total number of ways to select two items:

6 / 15 = 2 / 5

Therefore, the correct answer is option B) 6/30, which can be simplified to 2/5.

the Udderly Delicious Cheese Factory uses a total of 550 gallons of milk each day to produce 200 blocks of cheddar cheese and 200 blocks of Swiss cheese.

How to calculate the question?

To calculate the total gallons of milk used by the Udderly Delicious Cheese Factory each day, we need to determine the total quarts of milk used to produce 200 blocks of cheddar cheese and 200 blocks of Swiss cheese.

For the cheddar cheese production, we know that each block requires 5 quarts of milk, so for 200 blocks, the factory would need:

200 blocks x 5 quarts/block = 1000 quarts of milk

For the Swiss cheese production, we know that each block requires 6 quarts of milk, so for 200 blocks, the factory would need:

200 blocks x 6 quarts/block = 1200 quarts of milk

To find the total quarts of milk used by the factory each day, we can add the amount of milk used for cheddar cheese production to the amount used for Swiss cheese production:

1000 quarts + 1200 quarts = 2200 quarts

To convert quarts to gallons, we divide the total quarts by 4, since there are 4 quarts in 1 gallon:

2200 quarts / 4 = 550 gallons

Therefore, the Udderly Delicious Cheese Factory uses a total of 550 gallons of milk each day to produce 200 blocks of cheddar cheese and 200 blocks of Swiss cheese.

Answer:

  5 meters

Step-by-step explanation:

You want to know the width of a rectangular living room that is 12 m along one side and 13 m along the diagonal.

The diagonal of a rectangle is the hypotenuse of each of the right triangles it creates by dividing the rectangle in half. If one side length is 12 and the diagonal is 13, these measures are part of the {5, 12, 13} Pythagorean triple.

The width of the living room is 5 meters.

__

Additional comment

You can use the Pythagorean theorem to find the missing length:

  13² = 12² +w²

  169 -144 = w²

  w = √25 = 5

The width of the living room is 5 meters.

Other Pythagorean triples you see in algebra, trig, and geometry problems are {3, 4, 5}, {7, 24, 25}, {8, 15, 17}, {9, 40, 41} and their multiples.

The correct answer is (a) 114 standard hours.

To find the measured capacity of the work center, we need to add up the standard hours of work produced over the previous three weeks.

Step-by-step explanation:

This is a combination problem with repetition. Since there is an unlimited number of each type of cookie, we can choose 6 cookies from a pool of 4 types of cookies.

The formula for choosing r items from n types with repetition is:

(n + r - 1)C(r)

Where C is the combination function.

Using this formula, we can calculate the number of ways to choose 6 cookies:

(4 + 6 - 1)C(6) = 9C6 = 84

Therefore, there are 84 ways for Angelina to choose 6 cookies from Sam's Kookie shop, if she can choose any combination of chocolate chip, sugar, oatmeal, and snickerdoodle cookies with unlimited supply.

Charlie jumped farther than his younger brother, by a distance of (60L + 35)/L - 81 feet.

To compare the distances that Charlie and his younger brother jumped, we need to find a common unit of measurement. We can convert the mixed numbers into improper fractions to make the calculation easier.

Charlie jumped 81/1 feet, which is the same as 81 feet.

His younger brother jumped 35/L feet and then 21 feet. We don't know the exact value of L, but we can still compare the distances by assuming L is a constant value. So, the total distance his younger brother jumped is:

35/L + 21 feet

We can simplify the expression by finding a common denominator:

(35 + 21L)/L feet

To compare the distances, we can subtract the distances jumped by Charlie and his younger brother:

81 - (35 + 21L)/L

To determine who jumped farther, we need to simplify this expression by finding a common denominator:

(81L - 35 - 21L)/L

Simplifying further:

(60L + 35)/L

We don't know the exact value of L, but we can say that if L is any positive value, then 60L + 35 is greater than 81. Therefore, Charlie jumped farther than his younger brother, by a distance of (60L + 35)/L - 81 feet.

The scale factor used to dilate triangle ABC to triangle A'B'C' is approximately 4. So, correct option is C.

To determine the scale factor used to dilate triangle ABC to triangle A'B'C', we can use the formula:

scale factor = distance(A', B') / distance(A, B)

We can choose any pair of corresponding vertices to calculate the distance, but it's usually easiest to use the endpoints of a side. Let's use points A and A', and points B and B', respectively:

distance(A', B') = √[(12 - (-12))² + (12 - (-12))²] = √(24² + 24²)  ≈ 34

distance(A, B) = √[(3 - (-3))² + (3 - (-3))²] = √(6² + 6²) = 6√2

Substituting these values into the formula, we get:

scale factor = 34 / (6√2) ≈ 4

In the event of shortening the standard error of mean to 15 we have to increase the size to 400. Therefore, the correct answer is Option B.

The  given standard error of the mean for a sample of 100 is 30. So to cut the standard error of the mean to 15, we have to proceed by increasing the sample size to 400.

The  formula for evaluating the standard error of mean
SEM = SD / √(n)
here, SEM = standard error of the mean,
SD = standard deviation
n = sample size
Staging the values
15 = SD / √(100)
15 x √(100) = SD
SD = 150
Now evaluating for the value of n
