Answer:
Step-by-step explanation:
given that in a study conducted in 1980, researchers calculated the height difference between couples with kids in the UK. They found that the height difference between husband and wife follows a normal distribution with mean 5.6 inches and standard deviation equal to 3.7 inches.
a) The difference in height for 68% middle of couples in normal distribution is within 1 std dev from the mean
i.e. between (5.6-3.7, 5.6+3.7) = (1.9, 9.3) inches
b) P(x >5) = P(Z>0.6/3.7) = 1-0.5644= 0.4356
Percent = 43.56%
c) P(|x|<1) = P(-1<x<1) = F(1) -F(-1) = 0.0697
41/6-5/6 = 36/6
36/6= 6
So 5/6 would need to be subtracted to develop a fraction that divides to 6
Answer:
If you were to order them least to greatest, it would be:
4/8 < 9/16 < 4/6 < 3/4
If you were to order them greatest to least, it would be:
3/4 > 4/6 > 9/16 > 4/8
