Pls pls help im super confused
and pls show work not just answer

Step-by-step explanation:

multiply .20 by each of the students in the grade levels.

310x.20=62

358x.20=71.6

402x.20=80.4

you would do this because 20%=.20

he wants to survey 20% of students in each grade level so he would multiply .20 by each number of students in the grade level.

(does that make sense?)

2 and 1.

step-by-step explanation:

plug in each answer. 0 doesn't work, 1 does. so does 2. 4 doesn't:

0 = 1 is not true.

2 = 2 is true.

4 = 4 is true.

8 = 16 is not true.

hope this !
