Which of the following r-values represents the strongest correlation 0.62,0.50,0.32,0.45

0.62

Step-by-step explanation:

We know that when the r value is closer to the absolute value of 1 i.e. either 1 or -1, then it represents that there is a stronger correlation.

The given r-values : 0.62,0.50,0.32,0.45

From all the given correlation coefficient , the r value which closest to the absolute value of 1 is 0.62.

Therefore, the r-value that represents the strongest correlation = 0.62

93.8

step-by-step explanation:

lets say, first number = x

second number = 3x+7

total = 49

(x)+(3x+7)= 49

4x+7 = 49

4x = 42

x = 42/4

x= 10.5

x= 10.5

3x+7 = 3(10.5)+7 = 93.8

the system of inequalities is

step-by-step explanation:

step 1

find the equation of the dashed line

we have the points

(0,0) and (3,1)

the line passes through the origin, so, is a direct variation

find the slope

the equation of the dashed line is

the solution of the inequality a s the shaded area above the dashed line

therefore

the equation of the inequality a is

step 2

find the equation of the solid line

we have the points

(4,0) and (0,4)

find the slope

the equation of the solid line is

the solution of the inequality b s the shaded area below the solid line

therefore

the equation of the inequality b is

step 3

the system of inequalities is
