Answer:
$732.5
Step-by-step explanation:
Mae Ling earns a weekly salary of $365 which means salary per week is $365
Then plus a 7.5% commission on sales at a gift shop if she sold $4,900 worth of merchandise, which means additional
(0.075×4900)=367.5
The total she make will be
367.5+365
=$732.5
Therefore,she will make $732.5 in a work week if she sold $4,900 worth of merchandise
To approximate the P(x<27) we need to find the z-score of the data, this will be given by:
z=(x-μ)/σ
where:
μ-mean
σ-standard deviation
x=27, μ=32, σ=4
z=(27-32)/4
z=-5/4
z=-1.25
thus
P(x<27)=P(z<-1.25)
=0.1056
=10.56%
Answer: 10.56%
Answer: Coordinates for S (4,-13)
