We can only assume that the order amounts are uncorrelated.
.. normalcdf(104, 150, 102, 8/√(5)) = .288075061
The probability is about 28.8%.

Answer:
169.56 inches farther
Step-by-step explanation:
Eric: 30 x 3.14 = 94.2 inch per revolution
Maggie: 24 x 3.14 + 75.36 inch per revolution
94.2 x 9 = 847.8 inches
75.35 x 9 = 678.24 inches
847.8 - 678.24 = 169.56 inches farther
There's a relatively easy way to solve problems of this nature. You determine the contribution made if the only contributor is the one that contributes the least.
A chicken has the least number of feet, so 24 chickens will contribute 48 feet.
Now, you consider the change in contribution made by substituting a larger contributor. Each pig that replaces a chicken will add 2 feet to the total.
Consider how many feet need to be added, and thus how many larger contributors are needed. 80 -48 = 32 feet need to be added, so 32/2 = 16 of the animals need to be pigs.
There are 16 pigs and 8 chickens.
Answer:
15 1/12 feet
Step-by-step explanation:
Well if he descended 8 1/3 feet below the water, that means he must've went from board to water which is 6 3/4 feet then down 8 1/3 feet
6 3/4 + 8 1/3
= 6 9/12 + 8 4/12
=15 1/12 feet
