5^2 + 12^2 = c^2
25 + 144 = c^2
169 = c^2
take the square root of both sides
+ - 13 = c
Answer:
If simple interest, 2300+(2300*0.07)*9
If compound, 2300+(2300*0.07)^9
Answer: 30% of decrease
Step-by-step explanation:
$13.95 - $10 = $3.95
$13.95___100%
$3.95___x= 28.31%
(3.95*100) / 13.95 = 28.31 = 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.
