Let the original volume be pi *r^2* h where r = radius and h = height.
The new volume will be pi *(2/5 r)^2 * 4h = pi*4/25 r^2 4h
pi*4/25r^2 * 4h / pi r^2 h = 4/25 * 4 = 16/25
The volume has been reduced by factor of 16/25.
34960 × 2.5% = 1748 + 445 = 2,193 for the week (:
Answer:
Step-by-step explanation:
(Subtract 
from both sides of the equation to isolate 
)
(Simplify)
(Symmetric Property of Equality)
(Divide both sides of the equation by 
to get rid of 's coefficient; remember that 
, so 
has a coefficient of )
(Simplify)
Hope this helps!
Answer:
A
Step-by-step explanation:
As the sample size n increases, the sample mean (μy) becomes a more accurate estimate of the parametric mean, so the standard error of the mean becomes smaller. Therefore, the variance of y decreases and the distribution of y becomes highly concentrated around μy.
The area of a rectangle is base * altitude, and the perimeter is 2*base + 2*altitude,
base = 10cm and altitude = 7cm
