The weights of the fish in a certain lake are normally distributed with a mean of 14 lbs and a standard deviation of 5.5 lbs. If 35 fish are randomly selected, what is the probability that the mean weight will be less than 13.2 lbs?

step-by-step explanation:

6.48/4 4 goes into 6.48 1.62 times

45

step-by-step explanation:

to find a percentage, add a decimal in front and multiply it by the other number.

.25 times 180= 45

constant of proportionality = 3 and the equation is c = 3p.

step-by-step explanation:

c = kp   where c = amount of caffeine in mg., p = oz of pepsi and k is the constant of proportionality.

substituting the values given:

24 = 8k

k = 3.

the same value of k will be obtained if we substitute the other given values.
