<span>The correlation coefficient is a value that signifies correlation and dependence between two or more values. </span>The following statements are true:
- The correlation coefficient is a unitless number and must always lie between –1.0 and +1.0, inclusive.
- The correlation coefficient, r, gives us information about the strength and direction of a linear relationship between any two variables.
<span>- The larger r is in absolute value, the stronger the relationship is between the two variables.

<h2>Answer:</h2>

The correct statements are as follows:

Correlation coefficients are used to measure the strength, like weaker or stronger relationship between two variables.

The correlation coefficient is a unit less number and must always lie between –1.0 and +1.0, inclusive.

The correlation coefficient, r , gives us information about the strength and direction of a linear relationship between any two variables. We can say that r > 0 is a positive correlation and r < 0 is negative. |r| closer to 1 is a stronger correlation.

The larger r is in absolute value, the stronger the relationship is between the two variables.

Erica makes necklaces from beads. Each necklace consists of blue, white and green beads in the ratio of 6 : 4: 1 One necklace ne
Assoli18 [71]

Answer:

<u>For one Necklace you would need...</u>

24 blue beads.

16 white beads.

4 green beads.

Ratio: 24: 16: 4

Step-by-step explanation:

If you quadruple the amount of beads from the original amount (6 : 4: 1), the total beads for that necklace will be 44.

Step 1: 6 x 4 = 24 (amount of blue beads in necklace).

Step 2: 4 x 4 = 16 (amount of white beads in necklace).

Step 3: 1 x 4 = 4 (amount of green beads in necklace).

Now check to see if the total of all types of beads sum up to 44:

Step 4: 24 + 16 + 4 = 44

______________-

There is your answer:

You need 24 blue beads, 16 white beads, and 4 green beads to have a total sum of 44 beads in that one necklace.

15. Using the circle below, find each arc length. Round to the nearest hundredth. R a) ST b) RPT 97 125 PS = 28 feet
Troyanec [42]

The measure of arcPR and arcRPT are 83 and 208 degrees respectively

The measure of arc ST will be gotten using the expression below:

arcPS = arcPT + arcST

Given the following

  • arcPT = 125 degrees
  • arc PS = 180 degrees

arcST = arcPS - arcPT

arcST = 180  - 125

arcST = 55 degrees

Similarly, arcPR = 180 - arcRS

arcPR = 180 - 97

arcPR = 83 degrees

arcRPT = arcPR + arcPT

arcRPT = 83 + 125

arcRPT = 208 degrees

Hence the measure of arcPR and arcRPT are 83 and 208 degrees respectively
