Answer:

median = 17.5

Step-by-step explanation:

The median is the middle value of a data set arranged in ascending order. If there is not a middle value then the median is the average value of the numbers either side of the middle.

Data in ascending order is

8, 15, 17, 18, 19, 21

The median is between 17 and 18, hence

median = $\frac{17+18}{2}$ = 17.5

Answer:

Step-by-step explanation:

The median is the value that separates the higher half from the bottom half of the data sample (middle value).

We have

15, 8, 19, 21, 18, 17

Write from the smallest to the largest number

8, 15, 17, 18, 19, 21

We have an even number of numbers. Therefore we calculate the arithmetic mean of the two middle numbers:

8, 15, 17, 18, 19, 21

(17 + 18) : 2 = 35 : 2 = 17.5

Explain the distance formula. Then use it to calculate the

Answer:

$dAB=10\ units$

Step-by-step explanation:

we know that

The <u>distance formula</u> is derived by creating a triangle and using the Pythagorean theorem to find the length of the hypotenuse. The hypotenuse of the triangle is the distance between the two points

The formula to calculate the distance between two points is equal to

$d=\sqrt{(y2-y1)^{2}+(x2-x1)^{2}}$
