Which correlation coefficient represents a moderate negative correlation? r = –0. 04 r = –0. 24 r = –0. 64 r = –0. 94.

FinnZ [79.3K]

The correlation coefficient represents a moderate negative correlation is -0.64.

<h2>We have to determine</h2>

Which correlation coefficient represents a moderate negative correlation?

<h3>According to the question</h3>

The correlation coefficient is a measure of the strength of the linear relationship between two variables and is denoted by r.

The values between 0.3 and 0.7 indicate a moderate positive (negative) linear relationship.

The values between -0.3 and -0.7 indicate a moderate negative linear relationship.

The only value of r in the option is r= -0.64 lies in a given interval of the moderate negative linear relationship.

Hence, the correlation coefficient represents a moderate negative correlation is -0.64.

Which ordered pairs are solutions to the inequality 2x+y>−4?

hichkok12 [17]

we will proceed to resolve each case to determine the solution

we have

$2x+y>-4$

$y>-2x-4$

we know that

If an ordered pair is the solution of the inequality, then it must satisfy the inequality.

<u>case a)</u> $(5,-12)$

Substitute the value of x and y in the inequality

$-12>-2*5-4$

$-12>-14$ ------> is True

therefore

the ordered pair $(5,-12)$ is a solution of the inequality

<u>case b)</u> $(-3,0)$

Substitute the value of x and y in the inequality

$0>-2*-3-4$

$0>2$ ------> is False

therefore

the ordered pair $(-3,0)$ is not a solution of the inequality

<u>case c)</u> $(-1,-1)$

Substitute the value of x and y in the inequality

$-1>-2*-1-4$

$-1>-2$ ------> is True

therefore

the ordered pair $(-1,-1)$ is a solution of the inequality

<u>case d)</u> $(0,1)$

Substitute the value of x and y in the inequality

$1>-2*0-4$

$1>-4$ ------> is True

therefore

the ordered pair $(0,1)$ is a solution of the inequality

<u>case e)</u> $(4,-12)$

Substitute the value of x and y in the inequality

$-12>-2*4-4$

$-12>-12$ ------> is False

therefore

the ordered pair $(4,-12)$ is not a solution of the inequality

<u>Verify</u>

using a graphing tool

see the attached figure

the solution is the shaded area above the line

The points A,C, and D lies on the shaded area, therefore the ordered pairs A,C, and D are solution of the inequality

Roland needs 8 sheets of fabric that are each 45 yard long.

kompoz [17]

The total number of yards is 360 yards

<h3>How to determine the number of yards?</h3>

The given parameters are:

Number of sheets = 8

Yard per sheet = 45 yards

The total number of yards is calculated as:

Total number of yards = Number of sheets * Yard per sheet

Substitute the known values in the above equation

Total number of yards = 8 * 45 yards

Evaluate the product

Total number of yards = 360 yards

Hence, the total number of yards is 360 yards
