Answer:
235.62 cubed yards
Step-by-step explanation:
Area of a cylinder = pi(r^2)*h
pi(5^2)*3 = 235.62
Standard error (SE)

Or

Therefore, SE of the mean = (8)/(2) =4
The fourth one should be the correct answer
Answer:
x = 30
Step-by-step explanation:
1/2(x+6) = 18
Distribute
1/2 x + 3 = 18
Subtract 3 from each side
1/2x +3-3 = 18-3
1/2x = 15
Multiply each side by 2
1/2x*2 = 15*2
x = 30
Range is the difference between the lowest and highest values.
997- 247= 750
