Answer:
=0.1587 or 15.87%
So option A is correct answer so 15.87% of the invoices were paid within 15 days of receipt.
Step-by-step explanation:
In order to find the percent of the invoices paid within 5 days of receipt we have to find the value of Z first.
where:
X is the random varable which in our case is 15 days
u is the mean or average value which is 20 days
S is the standard deviation which is 5 days
Z=-1.0
We have to find Probability at Z less than -1
P(Z<-1.0) which can be written as:
=1-P(Z>1.0)
From Cumulative distribution table:
=1-(0.3413+0.5)
=0.1587 or 15.87%
So option A is correct answer so 15.87% of the invoices were paid within 15 days of receipt.
Answer: There is difference of $660 in their paychecks.
Step-by-step explanation:
Since we have given that
Number of hours in one week they worked = 40
Amount of sales = $78000
Kent makes $10 per hour plus 3% on the amount of sales .
So, the equation for Kent becomes,
Similarly, Bradley only makes $7 per hour but he makes 4% on the amount of his sales .
So, the equation for Bradley becomes,
hence, the difference between of their paychecks is given by
Therefore, there is difference of $660 in their paychecks.
