Answer:</h2><h2>The answer for the expression is 31</h2>
Step-by-step explanation:
The given expression is -4 + 5 + x + 4 = 36
To find the value of x, solve the given expression
Add the terms in the left hand side and compare with the right hand side to solve for "x"
-4 + 5 + x + 4 = 36
1 + x + 4 = 36
5 + x = 36
x = 36 - 5
x = 31
The z-score is -0.428
<h3>What is a z-score?</h3>
A z-score, also known as a standard score, provides information on how far a data point is from the mean. Technically speaking, however, it's a measurement of how many standard deviations a raw score is from or above the population mean.
You can plot a z-score on a normal distribution curve.
You must be aware of the mean and population standard deviation to use a z-score.
Z-scores allow results to be compared to a "normal" population.
According to the question,
x=500
μ=533
σ=77
z-score=(x-μ)/σ
On substituting the values,
z-score=(500-533)/77
= -0.428
