Rachel early $34 in 4 hours at her job today she wants to know how much she can earn tomorrow if she works 10 hours at the same hourly rate

$85

Step-by-step explanation:

Hi! First you need to divide $34 by 4 to see how much money she makes each hour.

$34 / 4 = $8.50

Now that you know how much she makes an hour, you can multiply this by 10 to find how much she will make if she works 10 hrs.

$8.50 * 10 = $85

Rachel will make $85 if she works 10 hrs.

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
