The X value corresponding to z = -0.75 will be 85. Then the correct option is A.
<h3>What is the z-score?</h3>
The z-score is a statistical evaluation of a value's correlation to the mean of a collection of values, expressed in terms of standard deviation.
The z-score is given as
z = (x - μ) / σ
Where μ is the mean, σ is the standard deviation, and x is the sample.
For a population with µ = 100 and σ = 20.
Then the X value corresponding to z = -0.75 will be
-0.75 = (x - 100) / 20
-15 = x - 100
x = 85
Then the correct option is A.

Answer:
B
Step-by-step explanation:
<span>4x = −4
</span>
Question 2
<span> 2(2x − 5 − 4) = 160 − 17
4x-10-8 = 160-17
4x-18=143
4x = 161
x=40.25
</span>
Question 3
<span>4(2z + 3) = 12
8z +12 = 12
8z = 0
z = 0
</span><span>Question 4
</span>
<span>5(2x − 6) + 20 = 10
10x-30+20=10
10x-10=10
10x =20
x=2
</span>
<span>Question 5
</span>
<span>5x + 10 = 5x − 8
5x+18=5x
18=0

When simplifying this, we would have to take this little by little in serious steps and not only this, but to also take notice of the use of <u>
pemdas</u>
and to make sure that we take each step carefully.
We first would <u>

simplify the following:
The answer is 44
The angles are supplementary meaning they add up to 180 degrees, so you subtract the 4 and get 176 then divide by 4 for the four x’s hope this helps
