A group of students want to determine if a person's height is linearly related to the distance they are able to jump.
Levart [38]

The correlation coefficient between the student's height and the distance they were able to jump is 0.86.

<h3>What is the correlation coefficient?</h3>

The correlation coefficient is a number that ranges from -1 to 1. It shows the strength of the relationship between two variables. It also shows the direction of the relationship.

Positive correlation is when the two variables move in the same direction. If one variable increases, the other variable also increases. Negative correlation is when two variables move in different direction. If one variable increases, the other variable decreases. Zero correlation is when there is no relationship between the variables.

The correlation coefficient is calculated using a financial calculator.

Here is the complete question:

A group of students want to determine if a person's height is linearly related to the distance they are able to jump.

To determine the relationship between a person's height and the distance they are able to jump, the group of students measured the height, in inches, of each person in their class and then measured the distance, in feet, they were able to jump from a marked starting point.

Each student was given three tries at the jump and their longest jump distance was recorded. The data the students collected is shown below.

Enter the correlation coefficient. Round your answer to the nearest hundredth.

Suppose a video store charges non-members $4 to rent a video. A membership costs $21 and then videos cost only $2.50 to rent. Ho
densk [106]

Answer:

You need to rent  14  videos, and you'll pay the same amount for both. Renting 15 will make the membership a better method of payment.

Step-by-step explanation:

Let Number of videos to be rented be x;

Given:

For non members;

Cost of renting 1 video = $4

Cost for renting x videos = 4x

For Members;

Membership cost = $21

Cost of renting 1 video =  $2.50

Cost of renting x video =  2.5x

We can create an equation. Say the number of videos you rent is given by x . We can write that, if we rent  x  videos without membership, we'll have to pay 4x . If we rent the same amount of videos with membership, we'll have to pay 21+2.5x.

Hence the equation can written as

4x=21+2.5x\\4x-2.5x=21\\1.5x=21\\x=\frac{21}{1.5}=14

Hence You need to rent  14  videos, and you'll pay the same amount for both. Renting 15 will make the membership a better method of payment.
