The smaller rectangle is like a smaller version of the big one, and 8 divided by 2 is four... so I think you need to divide 18 by 4, which is 4.5, so C is the answer
Big - small: multiply
Small - big: divide
I guess that u = μ & that a=σ. If so:
μ =100 & that σ =20 & x=20
Z score = (x-μ) / σ ==> Z score = (90-100)/20 ==> Z = - 0.5
14 - 10 = 4 + 5 = 9 x 2 = 18 I guess this is one way if I'm wrong try this way
14 - 10 = 4 x 2 =8 + 5 = 13
