Suppose the height (in inches) of adult males in the U. S.A are normally distributed with a mean of 72 inches and a standard deviation of 2 inches. Find the percent of men who are less than 68 inches tall.

Find the percent of men who are between 70 and 72 inches tall.

Find the percent of men who are at least 76 inches tall.

Find the probability that a randomly selected man is more than 72 inches tall.

Find the probability that a randomly selected man is between 68 and 76 inches tall.

Find the probability that a randomly selected man is less than 76 inches tall.

Between what 2 heights 68% of data fall?

How many standard deviations below the mean is the height of 70 inches?

The linear combination method is applied to a system of equations as shown. 4(.25x + .5y = 3.75) → x + 2y = 15 (4x – 8y = 12) → x – 2y = 3 2x = 18 what is the solution of the system of equations? (1,2) (3,9) (5,5) (9,3)

Using inductive reasoning, what is the next two numbers in this set? 1,-7,13,-19 i got the numbers 14,-26 is that right?

Acaterer knows he will need 60, 50, 80, 40 and 50 dinner napkins on five successive evenings. he can purchase new napkins initially at 25 cents each, after which he can have dirty napkins laundered by a fast one-day laundry service (i.e., dirty napkins given at the end of the day will be ready for use the following day) at 15 cents each, or by a slow two-day service at 8 cents each or both. the caterer wants to know how many napkins he should purchase initially and how many dirty napkins should be laundered by fast and slow service on each of the days in order to minimize his total costs. formulate the caterer’s problem as a linear program as follows (you must state any assumptions you make): a. define all variables clearly. how many are there? b. write out the constraints that must be satisfied, briefly explaining each. (do not simplify.) write out the objective function to be minimized. (do not simplify.)
