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:
(6 , 29/8)
Step-by-step explanation:
Let divide the segment into 8 equal parts (since 3 (CE) + 5(ED) = 8)
(11 - 3) / 8 = 8/8 = 1. So each x-segment will be 1 unit
(3 - 4) / 8 = -1/8. So each y-segment shall be -1/8 unit.
CE will represent 3/8 of the relative line.
Ex = 3 + 1 * 3 = 3 + 3 = 6
Ey = 4 + (-1/8) * 3 = 4 - 3/8 = 29/8
(6 , 29/8) is the final answer
First you need to combine like terms.
9x + 11y + 13
A coefficient is the number that comes before the variable (which is y).
The coefficient for y is 11.
Constants are the numbers that do not have variables attached to them.
The constant is 13.
Hope this helps!
Answer:
139 degrees
Step-by-step explanation:
we only have a central angle here (angle at the center of the circle).
and that angle remains the same along these 2 lines all the way out to the circle arc (and beyond, wherever these 2 lines take us).
so, if there is nothing missing in this graph, then x is the same as the inner angle : 139 degrees
