The probability that a sample of size n will have a mean,
, less that a given value, X, where the population mean,
, and the population standard deviation,
, is known is given by:
Therefore, the required probability is given by:
85 x 0.20= 17%

Answer:
For this case is the rectangle is dilated a factor of 2.2 we assume that the expansion is in all the dimensions so then the new length and width are:
Step-by-step explanation:
The area of a rectangle is given by
For this case is the rectangle is dilated a factor of 2.2 we assume that the expansion is in all the dimensions so then the new length and width are:
And the area would be (2.2)^2 times the initial area since is defined as

Answer:
0.245489 cubic meters.
Step-by-step explanation:
It is given that a firkin is an old British unit of volume equal to 9 gallons.
1 firkin = 9 gallons
6 firkins = 54 gallons
We need convert 6.00 firkins to cubic meters.
We know that,
1 gallon = 0.00454609 cubic meters
54 gallon = 0.24548886 cubic meters
6 firkins = 0.245489 cubic meters.
Therefore, 6.00 firkins is equivalent to 0.245489 cubic meters.
