Five hundred draws are made at random from the box 60,000 0 ’s 20,000 1 ’s true or false, and explain:
(a) the expected value for the percentage of 1’s among the draws is exactly 25%.
(b) the expected value for the percentage of 1’s among the draws is around 25%, give or take 2% or so.
(c) the percentage of 1’s among the draws will be around 25%, give or take 2% or so.
(d) the percentage of 1’s among the draws will be exactly 25%.
(e) the percentage of 1’s in the box is exactly 25%.
(f) the percentage of 1’s in the box is around 25%, give or take 2% or so.

$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
