The graph below shows three different normal distributions.
0
10
20
30
40
50
60
which statement must be true?
each distribution has the same mean and the same standard deviation.
each distribution has the same mean and a different standard deviation,
fach distribution has a different mean and the same standard deviation

area of part 1:

a1=base*height/2=(8+2)*(8-2-2-1)/2=10*3/2=15 ft^2

area of part 2:

a2=length*width=(8+2)*1=10 ft2

area of part 3:

a3=length*width=8*2=16 ft2

total shaded area : a1+a2+a3=41 ft2

total area of the reactangle : a=16*8=128 ft2

total area of the nonshaded region : 128-41=87 ft2

10 you would take 50/ .2
