Answer: 99.7% of data will fall within 3 standard deviations of the mean. The mean is 500 and the standard deviation is 100. ... Since we are only concerned with the scores from 500 to 700, we only want the half that is greater than the mean: 95/2 = 47.5%, or 0.475.:

54 = x + (x+6) + x + (x+6)
54 = 4x +12
42 = 4x
10.5 = x

The two shorter sides (x) are 10.5 cm, the two longer sides are (10.5+6, that is 6 cm longer) 16.5 cm. 10.5 + 10.5 + 16.5 + 16.5 = 54 cm.

Hmm

tr some
m=3
n=4
p=5
q=6
A=m/q=3/6=1/2=0.5
B=n/p=4/5=0.8

test
first,
A+B, andB is irrational
hmm, B is not irrational and the result is not irrational

2nd
0.5+0.8=1.3, it is rational

3rd the fraction is wrong
m/q times n/p=(mn)/(qp) so this is wrong

4th, fraction is also wrong (but it is true that produce of 2 rationals makes rational)

pick 2nd from top
