Sorry for not doing 4
16+64=80 80*2=160
or it means
64/2=32 32+16= 48
or it means
64+16=80 80/2= 40
this is a horribly formatted question
The first one because it’s the actual formula for a sphere and it has pie at the end because we are solving for a sphere
The answer is C because x2 is a parabola
Coefficient of variation is calculated by dividing the standard deviation by the mean multiplied by 100. Given a data set with mean equal to 60 and variance equal to 9, we can calculate the coefficient of variation by finding the value of the standard deviation which is the square root of the variance. so standard deviation is equal to square root of 9 which is 3. Then, the coefficient of variation is equal to 3/60*100 which is equal to 5%.
