1. Find the Median Average of these distances run by 8 marathon runners:
10 km, 15 km, 12 km, 14 km, 8km, 16 km, 11 km, 15 km

13

Step-by-step explanation:

Organizing the numbers

8 10 11 12 14 15 15 16

The median are both 12 and 14 but to get one median you add the two numbers 12 + 14 which equals 26. 26 divided by 2 numbers  equals 13

b. y = 4x - 2

step-by-step explanation:

to find a parallel equation to an equation, make sure both equations have the same slope but different y-intercepts.

y = 4x + 1

4 = slope

1 = y-intercept

y = 4x - 2

4 = slope

-2 = y-intercept

they both have the same slope but different y-intercepts, so, b. is the correct answer.

and to check your work, you can graph both equations. : )
