You'd get a total 24 cups, 3/5=9/15. 9+15=24

Answer:

take your pick. Each has its own reason.

Step-by-step explanation:

As with a lot of "doesn't belong" problems, the one that is different depends on your criteria. In the attached figure, each one "doesn't belong" for a different reason. Those reasons are listed below each number line.

__

I might choose the lower left: "addition, not subtraction", as it is the only one with arrows in the same direction. That makes its difference from the others more obvious, perhaps.

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

Pls answer the question

mariarad [96]

Option C:

(11 + 8) + 1 = 11 + (8 + 1)

Solution:

Let us first define the associative property of addition.

<u>Associative property of addition:</u>

(a + b) + c = a + (b + c)

Option A: 5 + 3 = 3 + 5

This represents a commutative property of addition.

i.e. a + b = b + a.

So, it is not true.

Option B: 6 + 1 = 6 + 1

This is not under the property of associative.

It is not true.

Option C: (11 + 8) + 1 = 11 + (8 + 1)

(a + b) + c = a + (b + c)

This reflects the associative property of addition.

It is true.

Option B is the correct answer.

Hence (11 + 8) + 1 = 11 + (8 + 1) illustrates the associative property of addition.
