How do I solve for x here?
emmasim [6.3K]
(x+108) and (x+88) are supplementary angles. This means that they add to 180.

(x+108) + (x+88) = 180

Solve for x:

2x + 196 = 180

2x = -16

x = -8

If SS= 162 from a sample of 15 data, find s^2
Genrish500 [490]

Answer:

11.57

Step-by-step explanation:

We have a simple formula to solve this:

s^2=\frac{SS}{n-1}

where

SS is sum of squares

s^2 is the variance, and

n is the number of data points

We are given all the info to find out s^2. Hence,

s^2=\frac{SS}{n-1}\\s^2=\frac{162}{15-1}\\s^2=\frac{162}{14}=11.57
