Answer:
The answer is B
Step-by-step explanation:
It's just a matter of following the sequence
You multiply the numbers, that will lead you to the answers. So 4/5 * 3/4 will give you the fraction of the girls with long brown hair.
To get the answer for Part B, do 4/5 * 3/4 * 1/3.
The value of the z is −2.1 then the probability P(z < −2.1) is 0.0179. Then the correct option is A.
<h3>What is a normal distribution?</h3>
It is also called the Gaussian Distribution. It is the most important continuous probability distribution. The curve looks like a bell, so it is also called a bell curve.
The z-score is a numerical measurement used in statistics of the value's relationship to the mean of a group of values, measured in terms of standards from the mean.
If the value of the z is −2.1. Then the probability will be
P(z < −2.1) = 0.0179.

Answer:
3 seconds
Step-by-step explanation:
We have to give us the following function h (t) = - 16 * t ^ 2 + 48 * t + 3
Now, they tell us that the height is 3 feet, therefore replacing that value we have left:
3 = -16 * t ^ 2 + 48 * t + 3, operating cancels 3. And it would be:
-16 * t ^ 2 + 48 * t = 0
Removing common factor -16 * t, it would be:
(-16 * t) * (t - 3) = 0
We have two solutions:
-16 * t = 0 ---> t = 0
t - 3 = 0 ---> t = 3
Because the time cannot be 0 seconds, the time it would take the ball in the air is 3 seconds.
Answer:
It is 23
Step-by-step explanation:
BC= FE
(x-4)=19
Therefore x= 23
