NO LINKS PLEASE- OR I SWEAR- What is the mean (average) of this data set? 50, 60, 60, 70 *

A. 70
B. 60
C. 80

60

Step-by-step explanation:

To find the mean;

add up the data

(50+60+60+70) =240

Then divide by the number of data points

240/4 = 60

The mean is 60

B.60

Step-by-step explanation:

mean=total sum/number of values

mean=50+60+70/3

•°•180/3=60

y=−9/2x+10

step-by-step explanation:

let's solve for y.

0−9x−2y=−20

step 1: add 9x to both sides.

−9x−2y+9x=−20+9x

−2y=9x−20

step 2: divide both sides by -2.

−2y

−2

=

9x−20

−2

y=

−9
