The correlation coefficient is -0.87; strong correlation
<h3>How to determine the correlation coefficient?</h3>
The given parameters are:
x = Time spent working out
y = lbs Overweight
Next, we enter the table of values in a graphing tool.
From the graphing tool, we have the following summary:
<u>X Values</u>
- ∑ = 27.1
- Mean = 2.71
- ∑(X - Mx)2 = SSx = 22.569
<u>Y Values</u>
- ∑ = 89
- Mean = 8.9
- ∑(Y - My)2 = SSy = 778.9
<u>X and Y Combined</u>
- N = 10
- ∑(X - Mx)(Y - My) = -114.19
<u>R Calculation</u>
r = ∑((X - My)(Y - Mx)) / √((SSx)(SSy))
r = -114.19 / √((22.569)(778.9))
r = -0.8613
Approximate
r = -0.87
This means that the correlation coefficient is -0.87
Also, the correlation coefficient is a strong correlation, because it is closer to -1 than it is to 0

Answer I think A
Step-by-step explanation:
<h2>
Hello!</h2>
The answer is: the price of 5 pints of tomato sauce is $2.25.
<h2>
Why?</h2>
To calculate how much does it cost 5 pints, we need to perform a unit conversion with the following unit relationship:

Now, calculating how much is a pint:

A pint is $0.45.
Then, calculating how much are 5 pints:

Hence, the price of 5 pints of tomato sauce is $2.25.
Have a nice day!
