Answer:
I got 70% hope it helps man
Let us assume the number of CDs Kate had = x
Number of CDs given to Sue = 5x/6
Number of CDs given to Joan = (5x/6) * ( 7/8)
= 35x/48
Number of CDs given to Ann = (35x/48) * (3/5)
= 7x/16
Total number of CDs Ann received = 70
Then
7x/16 = 70
x = 160
From the above deduction, it can be concluded that the number of CDs that Kate originally had was 160. I hope that this is the answer that has actually come to your help.
Answer:
CV for statistics exam = 15%
CV for calculus exam = 19%
Since the CV for calculus exam is higher, it has a greater spread relative to the mean than the statistics exam.
Step-by-step explanation:
To find coefficient variation we use the formula:
CV = (SD/mean) * 100
CV for the statistics exam:
where; SD= 5
mean= 75
CV = ( 5/75) *100
= 0.15 or 15%
CV for calculus exam
SD = 11
Mean= 58
CV= (11 /58) * 100
= 0.19 or 19%
