Answer:
A. 30
Step-by-step explanation:
sin theta = opposite side / hypotenuse
sin B = 8/16
sin B = 1/2
Take the arcsin of each side
arcsin sin(B) = arcsin (1/2)
B = arcsin (1/2)
B = 30
For a population with mean (μ) = 100 and standard deviation (σ) = 20, the X value corresponding to z = 1.50 is 130.
<h3>What is a z-score?</h3>
A z-score is also referred to as a standard score and it's a measure of the distance between a raw score and the mean, when standard deviation units are used.
<h3>How to determine the value of x?</h3>
In Statistics, the standardized z-score is giving by this formula:

Making x the subject of formula, we have:
x = Zσ + μ
Substituting the given parameters into the formula, we have;
x = 1.50(20) + 100
x = 30 + 100
x = 130.
