Hope that helps
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.
More about the normal distribution link is given below.

You basically do 80-70 as the numerator of a fraction which should equal 10 and then the denominater should be 80 so you then do 10 divided by 80 and multiply your answer by 100 Hope This Helps You
It’s x>1
Step-by-step
|3x+2|>3
step 1: add 2 both sides
|3x +2|-2+2>3+2
|3x+2|=5
step 2: solve absolute value
|3x+2|>2
we know either 3x+2> 3x+2<-5
3x+2>5 subtract two from both sides
3x+2-2>5-2
3x>3
Now divide three by both sides
X>1
2x - (3/4) = (15/4)
We need to get x by itself. First add 3/4 to both sides.
2x = 18/4
Now divide both sides by 2
x = 18/8 or 9/4
