Step-by-step explanation:
we know that
The area of the base of a cylinder is given by the formula

where
r is the radius of the circular base
If the radius is doubled
then

The new base area is


so

therefore
The new area of the base is 4 times the area of the original base
Answer:
see below
Step-by-step explanation:
9/10
To get as a fraction over 100, multiply the top and bottom by 10
9*10 90
------ = ------------
10*10 100
9/10 = 90/100
The decimal form for 9/10 is .9 and for 90/100 is .90

Answer:
And we can find the nnumber of deviations from the mean for each limit given:


So we are 3 deviation from the mean and using the empirical rule we know that within 3 deviations from the mean we have 99.7% of the values
Step-by-step explanation:
Let X the random variable that represent the amount of time it takes him to arrive, and for this case we know the distribution for X is given by:
Where
and
We want to find this probability:
And we can use the z score formula given by:
And we can find the nnumber of deviations from the mean for each limit given:


So we are 3 deviation from the mean and using the empirical rule we know that within 3 deviations from the mean we have 99.7% of the values
Answer:
1
Step-by-step explanation:
Any real number to the power of 0 is one (being that there is always a denominator of 1).
