Answer:
w(2w+4)
Step-by-step explanation:
we know A = l * w
and Perimeter = 2l + 2w
we want to find l in terms of w
2l + 2w = 6w + 8
2l = 4w + 8
l = 2w + 4
so A = w * (2w + 4)
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.
