90*1566=140,940 because how many means times
I believe it is c/6. Please correct me if I'm wrong.
It is a square, so all the sides are equal in length.
√196 = 14.
The sides are 14 by 14 meters.
Answer:
75,62.5
Step-by-step explanation:
Given that Mr. Dennis gave his class a 20-question multiple choice quiz. The distribution of raw scores had a mean of 15 and a standard deviation of 2.5
If X is the correct questions in the 20 mcq then
X is with mean = 15 and std dev = 2.5
when score is multiplied by 5
random variable now is
Y = 5x
E(Y) = Mean of Y = 

Thus new score out of 100 would have mean = 75 and std deviation = 62.5
