Answer: strong positive correlafion between data plan size 'x' and number of text messages sent 'y'

Step-by-step explanation:

'R' in statistics is used to denote correlation Coefficient. The correlation Coefficient is a value which ranges between -1 to +1. It tells us the level of relationship or correlation which exists between the relative movement of two variables, in this case the relationship between data plan size and the number of text messages sent in the US. R value of 0 depicts that no relationship exists between the two variables, R value closer the R value is to +1 and - 1 depicts the strength of positive and negative correlation of the two variables respectively.

A R value of +0.97 in the context above, depicts a strong positive correlation between data plan size and number of text messages sent in the US. That is large data size usually corresponds to large number of text messages and vice versa.

Please help me ......................
jekas [21]

Answer:

n = 18

Step-by-step explanation:

The formula for angle sum of a polygon is S = 180 (n - 2), where S is the sum and n is the sides.

We are given that the sum is 2880, and are trying to find n.

Simply sub in S = 2880,

2880 = 180 (n - 2)

Divide by 180 to get (n - 2) by themselves on the right side,

16 = n - 2

Now add 2 to the other side to get n by itself

18 = n

n = 18

Hope this helped!! Please feel free to ask me if there's anything you don't understand from this working
