Answer:

One sample t-test

Explanation:

The one sample t-test , also called single sample t test is a type of t test that measures the difference between a population mean and a hypothesized value,in this case the sample mean of widowed spouses that leave the house. The sample mean/hypothesized value is called the test value while the population mean is called the test variable. The one sample t test can only compare one sample mean to another given mean and not the mean of two samples or more.

On a map, Mary's house is located at (−3, 1) and the grocery store is located at (5, 7). Mary walks on a straight line from her
FrozenT [24]

The ordered pair that  represents the halfway point between Mary's home and the grocery store is (1, 4)

The midpoint (a, b) between two linear points (x_1, y_1) and (x_2, y_2) is calculated as:

a=\frac{x_1+x_2}{2} \\\\b=\frac{y_1+y_2}{2}

On a map, Mary's house is located at (−3, 1) and the grocery store is located at (5, 7).

x_1=-3, y_1=1, x_2=5, y_2=7

Substitute these values into the mid-point formulae

a=\frac{-3+5}{2} \\\\a=\frac{2}{2}\\\\a=1

b=\frac{1+7}{2} \\\\b=\frac{8}{2}\\\\b=4

The ordered pair that  represents the halfway point between Mary's home and the grocery store is (1, 4)

One railroad track was laid out on the line y = 8x - 2 by the engineers in charge. Which of the following lines could have been
kvv77 [185]
Y = 8x - 2.....slope here is 8. A parallel line will have the same slope.

The other line would be : y = 4 + 8x (or y = 8x + 4).....because they both have the same slope, which makes the lines parallel to each other
