The numbers of students in the schools in a district are given below. (Note that these are already ordered from least to greatest.)
168, 257, 277, 282, 335, 342, 398, 429
Suppose that the number 429 from this list changes to 341 . Answer the following.

(a) What happens to the mean?

It decreases by

It increases by

It stays the same.
(b) What happens to the median?

It decreases by

It increases by

It stays the same.

x> 6

step-by-step explanation:

8x+8> 7x+14

8x-7x> 14-8

x> 6

the system of inequalities is

step-by-step explanation:

step 1

find the equation of the dashed line

we have the points

(0,0) and (3,1)

the line passes through the origin, so, is a direct variation

find the slope

the equation of the dashed line is

the solution of the inequality a s the shaded area above the dashed line

therefore

the equation of the inequality a is

step 2

find the equation of the solid line

we have the points

(4,0) and (0,4)

find the slope

the equation of the solid line is

the solution of the inequality b s the shaded area below the solid line

therefore

the equation of the inequality b is

step 3

the system of inequalities is

(1, –1), (16, –4), (36, –6)

step-by-step explanation:

given that the function is

this can also be written as

we have to graph this function and check which list of points lie on the graph

see attachment for graph:

we find that the points lying are (1,-1) (16,-4) and (36,-6)

since square root is there we find that x can only be posiitve but y can be since square root both positive and negative.
