Answer:
Step-by-step explanation:
radius r = 5 cm
Height h = 5 cm
Volume of cylinder = πr²h
= π * 5 * 5 * 5
= 125π cm³
<u>Given</u>:
Given that the sides of the shape.
The given shape consists of 8 sides.
We need to determine the perimeter of the given shape.
<u>Perimeter</u>:
The perimeter of the figure can be determined by adding all the lengths of the sides of the shape.
Thus, we have;

Adding the values, we get;

Thus, the perimeter of the given shape is 36 feet.
Answer:
50,000 ≤ 23,210 + 5x
x = Average number of words per week
Step-by-step explanation:
Start off with 50,000 because that's how many words the paper needs to have.
Use "≤" because Trevor needs to write at least 50,000 words. (He can write more).
Trevor already wrote 23,210 words plus x words per week for 5 weeks.
(Solving for x will help you find the average number of words Trevor must write per week for 5 weeks).
Answer:
Where
and 
We are interested on this probability

And the best way to solve this problem is using the normal standard distribution and the z score given by:

If we apply this formula to our probability we got this:
And we can find this probability using the complement rule:

Step-by-step explanation:
Previous concepts
Normal distribution, is a "probability distribution that is symmetric about the mean, showing that data near the mean are more frequent in occurrence than data far from the mean".
The Z-score is "a numerical measurement used in statistics of a value's relationship to the mean (average) of a group of values, measured in terms of standard deviations from the mean".
Solution to the problem
Let X the random variable that represent the variable of interest of a population, and for this case we know the distribution for X is given by:
Where
and 
We are interested on this probability

And the best way to solve this problem is using the normal standard distribution and the z score given by:

If we apply this formula to our probability we got this:
And we can find this probability using the complement rule:
