For the following set of temperatures recorded during 7 days in Hartford, find the mean. 51º, 530, 640, 499, 64º, 540, 50°
The mean is

means is 339.142 degrees

Step-by-step explanation:

mean= sum of all values /number of values

mean=2374/7

mean=339.142

this is answer of 144 cubic meters

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. : )
