Answer:
Part A) 
Part B) 
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
----> by definition of parallelogram (opposite angles are congruent)
substitute the given values

solve for x

step 2
Find the measure of angle R

substitute the value of x

step 3
Find the measure of angle S
we know that
---> by definition of parallelogram (consecutive angles are supplementary)
we have

substitute



answer
B)0.66
Step-by-step explanation:
0.66 value of the correlation coefficient r of the data set
C. y = 0.5x.
The coefficient of x is the slope of the line. From the picture, you can see that the slope of the blue line is half the slope of the black line.
Answer:
h < 2
Step-by-step explanation:
Step 1: Distribute
10h + 40 < 60
Step 2: Subtract 40 on both sides
10h < 20
Step 3: Divide both sides by 10
h < 2
