Answer:
r = 0
Step-by-step explanation:
First, combine like terms:
(-2r - 4r) = 0
(-6r) = 0
Isolate the variable, r. Divide - 6 from both sides:
(-6r)/-6 = (0)/-6
r = 0/-6 = 0
r = 0 is your answer.

Answer:
52
Step-by-step explanation:
Given that :
Mean (m) = 78
Standard deviation (s) = 13
Score that is 2 standard deviations below the mean
Using the relation :
Zscore = (x - m) / s
2 standard deviations below the mean means a Zscore of - 2
Hence,
-2 = (x - 78) / 13
Cross multiply
-2 * 13 = x - 78
-26 = x - 78
x = - 26 + 78
x = 52
Score which is 2 standard deviations below the mean is 52
