The value of a correlation coefficient ranges between -1 and 1.

The greater the absolute value of the Pearson product-moment correlation coefficient, the stronger the linearrelationship.

The strongest linear relationship is indicated by a correlation coefficient of -1 or 1.

The weakest linear relationship is indicated by a correlation coefficient equal to 0.

A positive correlation means that if one variable gets bigger, the other variable tends to get bigger.

A negative correlation means that if one variable gets bigger, the other variable tends to get smaller.

therefore

d is correct

-0.9

Serggg [28]

Answer:

Hey there!

We can write this equation, where x is the hourly rate and y is the fixed fee.

4x+y=270

7x+y=420

4x+y=270

-7x-y=-420

-3x=-150

x=50

4(50)+y=270

200+y=270

y=70.

The fixed fee is G. $70.

Let me know if this helps :)

erma4kov [3.2K]

Answer: The 36th caller will be the first one to win both

Step-by-step explanation:

Given: A radio station is having a promotion in which every 12th caller receives a free concert ticket and every 9th caller receives a limo ride.

To find which caller would be the first one to win both, we will find the LCM.

Prime factorization of 9 and 12:

12 = 3x 2x 2

9 = 3x 3

LCM(12,9)=3\times2\times2\times3=36  [Where LCM=Least common multiple]

Therefore, the 36th caller will be the first one to win both.
