For a population with = 100 and = 20, what is the x value corresponding to z = 1.50?
1 answer:
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.

Answer:
x = 28
Step-by-step explanation:
The ratios of corresponding sides are equal, that is
=
( cross- multiply )
8(x - 7) = 168 ( divide both sides by 8 )
x - 7 = 21 ( add 7 to both sides )
x = 28
Answer:
{2,3,4,5}
Step-by-step explanation:
Domain is the set of x-values for which the function is defined.
Range is the set of y-values for which the function is defined (set of values corresponding to the set of x-values).
The function is given as
The domain is (-2,0,2,4)
That means, we need to plug-in the 4 numbers given into x of the function and find the 4 corresponding y values (the range).
So, lets do this:
putting x = -2,
putting x = 0
y = 3
putting x = 2
putting x= 4
Thus, the range is {2,3,4,5}
