Answer: There are a lot of examples of this, but in short, any number that can be written as 1/2 is your answer. Think about it, 5 is half of 10. So that means that 20/40, 6/12, 3/6, 70/140, etc are all equal

Cloud [144]

Answer:

Devin will need 9 cubes of wax.

Step-by-step explanation:

To find the volume of the pyramid, you use (area of the base)* height of the pyramid divided by 3. You know the volume of a cube of wax is 32 cm^3. The volume of your pyramid is 270 cm^3. 270/32=8.4375.

Once you get 8.4375 cubes, you round to the next whole number, which is nine.

Use a graphing calculator to find the value of the correlation coefficient r and determine if there is a strong correlation amon

Natali [406]

The value of the correlation is -0.0721 and it is a weak negative correlation

<h3>How to determine the correlation coefficient?</h3>

The points are given as:

(12, 28), (15, 50), (18, 14), (21, 28), (24, 36)

Enter the above points in a graphing calculator.

From the graphing calculator, we have the following summary:

<u>X Values</u>

Sum X = 90
Mean = 18
∑(X - Mx)^2 = SSx = 90

<u>Y Values</u>

Sum Y = 156
Mean = 31.2
∑(Y - My)^2 = SSy = 692.8

<u>X and Y Combined</u>

N = 5
∑(X - Mx)(Y - My) = -18

<u>R Calculation</u>

r = ∑((X - My)(Y - Mx)) / √((SSx)(SSy))

This gives

r = -18 / √((90)(692.8)) = -0.0721

So, the correlation coefficient is -0.0721

The above is a negative correlation because it is less than 0 and it is a weak correlation because it is closer to 0 than -1

Hence, the correlation is a weak negative correlation
