Answer:
I think she is incorrect she need to change all the fractions to the same denominators
Step-by-step explanation:
We are going to change all the fractions to 64
9/64 stays the same
5/32 multiply 2 then 10/64
1/16 multiply by 4 then 4/64
1/8 multiply by 8 then 8/64
Now we can order then
5/32 > 9/64 > 1/8 > 1/16 This is the right order
She was wrong.
In pretty sure the answer is b
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%
