D.
Step-by-step explanation:
First, multiply straight across and put everything together:
Notice we can simplify by cancelling a b and reducing 3/12:
This cannot be simplified further.

<h3><u>The two inequalities are:</u></h3>
Let "a" be the number of adult sized t shirts
Let "c" be the number of child sized t shirts
Given that,
Each Adult sized t shirts = $ 5
Each child sized t shirts = $ 2.50
<h3><u>Jerome need at least 200 adults t-shirt</u></h3>Therefore,
Here, we used "greater than or equal to" symbol, since he needs atleast 200 adult t-shirts
<h3><u>Jerome will spend no more than $1500 on t-shirt</u></h3>Therefore,
Here we used, "less than or equal to" symbol, since he will not spend more than 1500
Thus the two inequalities are found
A normally distributed data set has a mean of 0 and a standard deviation of 2. The closest to the percent of values between -4.0 and 2.0 would be 84%.
<h3>What is the empirical rule?</h3>According to the empirical rule, also known as the 68-95-99.7 rule, the percentage of values that lie within an interval with 68%, 95%, and 99.7% of the values lies within one, two, or three standard deviations of the mean of the distribution.
A normally distributed data set has a mean of 0 and a standard deviation of 2.

The shaded areas add to 2/5 of the area of the circle, which is given by
A = πr²
Then the shaded area is ...
(2/5)A = (2/5)π(10 in)²
shaded area = 40π in²
A = πr²
Then the shaded area is ...
(2/5)A = (2/5)π(10 in)²
shaded area = 40π in²
