Engineers must consider the breadths of male heads when designing motorcycle helmets. Men have head breadths that are normally distributed with a mean of 6.0 in and a standard deviation of 1.0 in (based on anthropometric survey data from Gordon, Churchill, et al.).
If one male is randomly selected, find the probability that his head breadth is less than 6.2 in. Find the probability that 30 randomly selected men have a mean head breadth less than 6.2 in. State why the central limit theorem can be used.
Find the probability that 100 randomly selected men have a mean head breadth less than 6.2 in. State why the central limit theorem can be used.

Tomas is making trail mix using granola and walnuts. he can spend a total of $12 on the ingredients. he buys 3 pounds of granola that costs $2.00 per pound. the walnuts cost $6 per pound. he uses the equation to represent the total cost, where x represents the number of pounds of granola and y represents the number of pounds of walnuts. he solves the equation for y, the number of pounds of walnuts he can buy. answer- b tomas added 6 to both sides of the equation instead of subtracting 6. just took the test
