Quarters equal 25 cents so multiply 25 x32
Name Score
Julia 650
Andrew 550
Jason 380
Cathy 720
Jessica 710
Robert 550
Point estimate for the mean score:
Sample mean = sum of all observations / number of observations
sample mean = (650+550+380+720+710+550) / 6
sample mean = 3560 / 6
sample mean = 593.33
The point estimate for the mean score is 593.33
Y=14.5
x=7
40=(34-2x)+(3x-1)
140=(3y+6)+(5y+18)
Answer:
The volume of cylinder is calculated by:
V = base area x height = pi x radius^2 x height
=> 3617.28 = 3.14 x 12^2 x height
=> 3617.28 = 452.16 x height
=> height = 3617.28/452.16 = 8 (cm)
Hope this helps!
