98%, Just add all of the numbers up to find the original average, then try to get the average up to what you want it to be.

If h(x) = 5x - 3 and j(x) = -2x, solve hlj(2)] and select the correct answer below. (1 point)

Answer:

-23

Step-by-step explanation:

We are given the functions;

h(x) = 5x - 3 and j(x) = -2x

Now, we want to find h[j(2)]

j(2) = -2(2)

j(2) = -4

Thus;

h(-4) = 5(-4) - 3

h(-4) = -20 - 3

h(-4) = - 23

Answer:

D is not a supported statement

Step-by-step explanation:

Let take them one by one:

A: from table: 0.57; in statement: 0.5

0.57 > 0.5 so this is supported

B: from table: 0.2+0.16=0.36; in statement: 1/3=0.33,

0.36>0.33 so this is supported

C: 0.07 is the least, so this is supported

D: the table DOES NOT show number of students, but proportions. So statement '7 students' IS NOT supported

E: from table 0.20 overslept. 0.2 < 1/4=0.25, so this is supported
