Answer:

Step-by-step explanation:

The answer is 60/12 becuase we can simfly both of theese mixed numbers into an improper fraction, wich will be 4/3*15/4. We do the multiplication, and we get 60/12. 60/12 can be simplifed to 5 becuase 60 divided by 12 is 5

Answer:

<u>⅓</u>

<h2>Step-by-step explanation:</h2>

$\frac{5}{9} \times \frac{3}{5}$

$= \frac{1}{3} \times \frac{1}{1}$

$= \frac{1}{3}$

<h2>Checking:</h2>

$\frac{1}{3} \div \frac{3}{5}$

$= \frac{1}{3} \times \frac{5}{3}$

$= \frac{5}{9}$

5. Rounded to three decimal places, what is the value of r for this data set?

IrinaVladis [17]

The value of correlation coefficient (r) for the dataset is 0.981

<h3>What is correlation coefficient (r)?</h3>

The correlation coefficient (r) is used to determine the closeness and association of a scatter plot points.

The dataset is given as:

x: 8 15 3 7 2 14
y: 15 21 6 12 3 20

Using a graphing calculator, we have the following parameters:

<h3>X Values </h3>

∑x = 49
Mean = 8.167
∑(X - Mx)2 = SSx = 146.833

<h3>Y Values </h3>

∑y = 77
Mean = 12.833
∑(Y - My)2 = SSy = 266.833

<h3>X and Y Combined </h3>

N = 6
∑(X - Mx)(Y - My) = 194.167

The correlation coefficient (r) is then calculated as:

$r = \frac{\sum{((x - My)(Y - Mx)) }}{ \sqrt{((SSx)(SSy))}}$

This gives

$r = \frac{194.167 }{ \sqrt{((146.833)(266.833))}}\\$

$r = 0.9809$

Approximate

$r = 0.981$

Hence, the value of correlation coefficient (r) for the dataset is 0.981
