Test scores: Scores on a statistics exam had a mean of 75 with a standard deviation of 5. Scores on a calculus exam had a mean o
beks73 [17]

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%

What is the best approximate for the volume of cement used to make one of these spheres?
forsale [732]

Since we have that the volume of a sphere is given by:

V=\frac{3}{4}\pi r^3

And we have that the diameter equals 3.6ft, we then will have a volume of:

V=\frac{3}{4}\pi(1.8)^3\Rightarrow V\approx13.74

Since we have that the volume is approximately 13.74 ft^3, then the best approximation in the problem is A. 13.6 ft^3.
