This problem can be modeled by the picture shown below. We notice that we are given to side lengths, specifically legs, of the triangle. Therefore, we can use the Pythagorean Theorem, which states that a^2+b^2=c^2, where a and b are legs and c is the hypotenuse. So we can do:
16^2+12^2=c^2
256+144=c^2
400=c^2
The square root of 400 is
20, which is our hypotenuse.
(You might wonder why we used 12, that is because the whole base length is 24, but we only need half of the base to use the Pythagorean Theorem. 24/2 is 12).

Answer:
A
Step-by-step explanation:
I have no idea, someone help
The sum of two adjacent sides is 11 inches, so the long sides are 9 inches. The "unknown number" must be 12.
Answer:
Step-by-step explanation:
We are given the following in the question:
Population mean, μ = 108
Sample mean,
= 107
Sample size, n = 110
Alpha, α = 0.02
Population standard deviation, σ = 7
Formula:
Putting all the values, we have

The test statistic is -1.50
