Solution:
The ratio of the volumes is 81:1
Explanation:
We have been given that the radii of two similar cones are in the ratio 9:1.
Let a be the radius of first cone and b be the radius of second cone. Then, we have
The volume of the cone is given by
Since, the cones are similar hence, the ratio of volume of these cone is equal to the ratio of the square of the radius.
Thus, the ratio of volume is given by
Therefore, the ratio of the volumes is 81:1
The probability that a randomly sample of a normally distributed data with a mean, μ, and standard deviation, σ, is between two numbers (a, b) is given by:
Given that the <span>september energy consumption levels for single-family homes are found to be normally distributed with a mean of 1050 kwh and a standard deviation of 218 kwh.
The probability that the september energy consumption level of a randomly selected home is between 1100 kwh and 1225 kwh is given by:
