If the outlier is excluded from the following data set, what happens to the mean? 110, 112, 109, 112, 21, 108, 110, 111, 108

A . It decreases.

B . It increases.

C . It does not change.

D . It depends whether the outlier is a high outlier or a low outlier.

With the outlier, the average is 100.1

Without it, the average is 110.

So without the outlier, the mean increases.

Step-by-step explanation:

The outlier is 21. Think about it in terms of grades. If your lowest grade is taken off your report card, your average would increase

option 2 is correct.

step-by-step explanation:

we are given two inequality equation

x+y> 5 and -3x+2y< -2

first we draw the graph of both function using t-table method

equation: x+y> 5

for x=0, y=5

for x=-5, y=0

table:

x   :   0     5

y   :   5     0

test point (0,0) , 0> 5

false

equation: -3x+2y< -2

for x=0, y=-1

for x=2, y=4

table:

x   :   0     2

y   : -1       4

test point (0,0) , 0< -2

true

now we draw the graph. see the attachment for graph.

common region would be solution set.

option 2 is correct.
