Answer:
50 in ^3
Step-by-step explanation:
V = 1/3 pi r^2 h
We know that pi = 3
the diameter is 5 so the radius is 1/2 the diameter of 5/2 = 2.5
The height is 8
V = 1/3 ( 3) ( 2.5)^2 ( 8)
V = 50 in ^3
Answer:
Step-by-step explanation:
we know that
A relationship between two variables, x, and y, represent a direct variation if it can be expressed in the form 
or 
In this problem we have
y=18 when x=2
Find the value of the constant of proportionality k
----> 
therefore
The equation is equal to
Answer:
The standard deviation of the set is: 1.5
Step-by-step explanation:
The actual standard deviation is 1.58... but to 1 decimal place it's 1.5
Answer:
y = lnx / ln 7.
Step-by-step explanation:
x = 7^y
Take logarithms of both sides:
ln x = ln 7^y
ln x = y ln 7 ( because ln a^b = b ln a. One of the Laws of Logarithms).
y = lnx / ln 7.
Pretty sure its 132
Hope this helps!
