Answer:
<h2>c. 16.5</h2>
Step-by-step explanation:
It's the right triangle.
The formula of an area of a right triangle:
Look at the picture.
We have
Substitute:
The answer is D. You are just adding 8 to the number of hours you work because you earn 8 dollars an hour, or you can just multiply the number of hours by the wage you get paid and you would get the your gross pay. It would also be in quadrant 1 because all the numbers are positive and quadrant 1 is all positive numbers not like the other quadrants where there is either all negative numbers or some positive numbers and some negative numbers. But to make things shorter the answer is D.
The first step to solving this is to remember our mathematical rules. They state that when the term has a coefficient of -1,, the number doesn't have to be written but the sign needs to remain. This will change the expression to the following:
x - v + 4 + 7y - 3
Now subtract the numbers 4 and 3 from each other.
x - v + 1 + 7y
Since this expression cannot be simplified any further,, the correct answer to your question would be x - v + 1 + 7y.

The probability is P = 0.004, so the correct option is D.
<h3 /><h3>How to find the probability?</h3>
We want to find the probability that 4 students lie on these 30% subgroup.
We know that there are 30 students, the 30% of 30 is:
x = (30%/100%)*30 = 9
So 9 out of 30 students prefer the tests to be on Mondays.
The probability that the first randomly selected kid wants the test to be on Monday is:
p= 9/30
For the next kid, the probability is:
p'= 8/29 (because one kid was already selected).
For the next one:
p'' =7/28
For the final one:
p''' =6/27
The joint probability is the product of these 4:
P = (9/30)*(8/29)*(7/28)*(6/27) = 0.004
So the correct option is D.
