Answer:
Step-by-step explanation:
This is asking what is A
Formula A squared + B squared = C squared
A=x
B=8
C=20
X^2+ 8^2=20^2
8 squared is 64
20 squared is 400
400-64 is 336
X*X=336 find the square root of 336 =18.3
CHECK
18.3*18.3+ 8*8=398.89 which is super close to 400

<h3>24) Part 1 - Here is the equation:</h3>
![16(5-3+2)](https://tex.z-dn.net/?f=%2016%285-3%2B2%29%20)
Use PEMDAS
![Parentheses \\ Exponents \\ Multiplication \\ Division \\ Addition \\ Subtraction](https://tex.z-dn.net/?f=%20Parentheses%20%5C%5C%20Exponents%20%5C%5C%20Multiplication%20%5C%5C%20Division%20%5C%5C%20Addition%20%5C%5C%20Subtraction%20)
<em>Parentheses is first. Start from left to right.</em>
![5-3 = 2 \\ 2+2= \bf4](https://tex.z-dn.net/?f=%205-3%20%3D%202%20%5C%5C%202%2B2%3D%20%5Cbf4%20)
<em>New equation:</em>
![16(4)](https://tex.z-dn.net/?f=%2016%284%29%20)
<em>When numbers are together without a sign, that means you have to multiply. Multiply 16 by 4</em>
![16 \times 4 = 64](https://tex.z-dn.net/?f=%2016%20%5Ctimes%204%20%3D%2064%20)
<u><em>ANSWER </em></u>= 64
<h3>24) Part 2 - Here is the equation:</h3>
![17-3 \times 4+2](https://tex.z-dn.net/?f=%2017-3%20%5Ctimes%204%2B2%20)

<em>Multiplication is first</em>
![4 \times 3 = 12](https://tex.z-dn.net/?f=%204%20%5Ctimes%203%20%3D%2012%20)

<em>Start from left to right.</em>
![17-12 = 5 \\ 5+2 = 7](https://tex.z-dn.net/?f=%2017-12%20%3D%205%20%5C%5C%205%2B2%20%3D%207%20)

Answer:
Step-by-step explanation:
In statistical hypothesis testing we use p values. For any test we select significance level alpha as 5% or 1% or 10%
Whenever p < alpha we reject our null hypothesis. Otherwise we accept our null hypothesis.
Hence p should be high to accept null hypothesis
Option A is incorrect
B is correct
C is wrong as p is the probability
D False
Option B is right.
