Answer:
Both variables Can tell you the degree to which a linear relationship exists between two variables.
Step-by-step explanation:
Correlation and regression are two statistical concepts that are closely related and complement each other. They are powerful tools used in modern-day machine learning and artificial intelligence.
Correlation evaluates the linear relationship between two variables, using regression as a tool to assess the degree at which a dependant variable changes ( either increasing or decreasing ) based on the value of an independent variable.
The correlation coefficient is the degree of the linear relationship between two variables, ranging from zero ( for non-linear) to one ( for highly linear).
First you would have to find the cost for 1 medium pizza.
10.50/3=3.5
It costs $3.50 for 1 medium pizza
Next, you would have to multiply 3.5 times 10.
3.5*10=35
It costs $35.00 for 10 medium pizza's.
52² − 48² = (2704 + 2304)(2704 − 2304) = 2,003,200
52² − 48² = (52 + 48)(52 − 48) = 100 * 4 = 400
a² - b² = (a +b)*(a-b)
52² − 48² = 2704 − 2304 = 400

Answer:
18 questions
Step-by-step explanation:
22 questions=55%
??? questions=45%
now what about this:
2 questions=5%
I just simplified the first equation
now 5%*???=45%
5*9=45
then we do the same thing to the other side
2*9 questions=45%
18 questions are left on the survey
Answer: 15
<u>Step-by-step explanation:</u>
small: 5 12 13
middle: __ 36 39
large: 45 108 117
Notice that to get from the small to the large, multiplied by 9
5(9) = 45 12(9) = 108 13(9) = 117
That is because the sides are proportional 
To get from small to middle, multiply by 3
5(3) = 15 12(3) = 36 13(3) = 39
To solve it using proportions:
