The volume of a cone is given by the formula
, where <em>r</em> is the radius and <em>h</em> is the height. The horizontal dotted line from the center of the base circle to the outside edge would be the radius, so that would be 12 cm. The vertical dotted line from the center of the base to the point of the cone would be the height, so that would be 8 cm. We substitute these values into our formula:
Substituting 3.14 for pi we have:
Answer:
Step-by-step explanation:
This problem can be solved using concept of compound interest
In compound interest
if p is the principal amount
and r is the interest rate
then value of principal amount(A) after n years time is given by
A = p(1+r)^n
=>
__________________________________
in the problem
in place of n we have x years
y is the amount which is the total amount after n years
p is the principal money deposited = $500
r = 15%
substituting these value in the formula for amount after n years we have
Thus, function modeling the situation is
Answer: 81% of the variance in dependent variable is explained by this correlation .
Step-by-step explanation:
For X = Independent variable and Y=dependent variable,
If r= correlation coefficient , then we say <em> </em>of the<em> </em>variance in Y is explained by Variable X.
Given: r= 0.90
So, 81% of the variance in dependent variable is explained by this correlation .
Hello!
A proportion is an equation that states two ratios are equal. (Note that these ratios are usually written as fractions).
I hope this helps!
