Jackie has $36 in her purse. This is 75% of all the money she has from babysitting this week. How much money does she have in total?
А
$9
B $12
C $27
D) $48

the answer is D. $48

Step-by-step explanation:

All you have to do is divide 36 by 75%,

so put 36 ÷ 0.75 into your calculator and 48 is your answer!

You also could've done a process of elimination.

A, B, and C are clearly not the answer bc Jackie already has $36 in her purse and the question tells us that the $36 is only 75% of all the money she has, so we are looking for a number bigger than 36.

S, D. is our only logical answer since it is $48 and the last time checked 48 is greater than 36.

hope this helps!!!

answer: expected value of x = 1.0

step-by-step explanation:

p(x=0) = 0.25

p(x=1) = 0.50

p(x=2) = 0.25

expected value for x = 0×0.25 + 1×0.5 + 2×0.25 = 1.0
