7nadin3 [17]2 years ago
5 0

The correct options related to the correlation coefficient are basically that it presents the strength of the relationship,it presents the direction of the relationship and it varies from -1 to 1.

Given four options related to correlation coefficient.

We are required to choose the correct options related to correlation coefficient.

The correlation coefficient is basically the specific measure that quantifies the strength of the linear relationship between two variables in a correlation analysis. The coefficient is basically  symbolize with the r in a correlation report.

The correct options related to correlation coefficent are:

  • Presents the strength of the relationship,
  • Presents the direction of the relationship,
  • Varies from -1 to 1.

Hence the correct options related to the correlation coefficient are basically that it presents the strength of the relationship,it presents the direction of the relationship and it varies from -1 to 1.

In parallelogram RSWY, find m
LuckyWell [14K]

Answer:

Part A) m\angle R=110^o

Part B) m\angle S=70^o

Step-by-step explanation:

we know that

In a parallelogram, opposite angles are congruent and consecutive angles are supplementary

step 1

Find the value of x

we know that

m\angle R=m\angle W ----> by definition of parallelogram (opposite angles are congruent)

substitute the given values

(5x-90)^o=(2x+30)^o

solve for x

5x-2x=30+90\\3x=120\\x=40^o

step 2

Find the measure of angle R

m\angle R=(5x-90)^o

substitute the value of x

m\angle R=(5(40)-90)=110^o

step 3

Find the measure of angle S

we know that

m\angle R+m\angle S=180^o ---> by definition of parallelogram (consecutive angles are supplementary)

we have

m\angle R=110^o

substitute

110^o+m\angle S=180^o

m\angle S=180^o-110^o

m\angle S=70^o
