What is the expected value of the distribution? 0 1
A local charity holds a carnival to raise money. In one
activity, participants make a $3 donation for a chance to
spin a wheel that has 10 spaces marked with the
values 0, 1, 2, 5, and 10. The participant wins the dollar
amount marked on the space on which the wheel
stops. Let X represent the value of a spin. The
distribution of X is given in the table.

step-by-step explanation:

divide 13.5 by 9 to get the scale factor. it equals 1.5

2 * 1.5 = 3

r = 78539458390583095803458309458039485093485 or just 3

step-by-step explanation:

$2416.6

step-by-step explanation:

per hour = $ 25

total work time = 35

commission = 15%

total she has to make = $ 4,500

let she sold x dollar products

so her commission will be 15 % of x

now

total = weekly basic pay + commission

4500= (25*35) + 15 % of x

4500=875 + * x

4500-875 =   * x

3625= * x

multiplying wwith 100 on both sides gives

36250 = 15 x

now

x =  

x= $2416.6
