Let X be the iq score of adults. X is normally distributed with mean of 100 and standard deviation of 20.
If all iq scores are converted to z -scores then we will get z scores. And the z score is standard normal variable with mean=0 and standard deviation =1
Hence the mean and standard deviation of of all z scores will be 0 and 1 respectively.
Answer:

8. 2/8
Step-by-step explanation:
Assume the triangle has 3 sides with length of 5, 6, and sqrt(11)
So cotθ = 1/tan<span>θ = 1/(5/sqrt(11)) = sqrt(11)/5</span>
