A manufacturer produces a commodity where the length of the commodity has approximately normal distribution with a mean of 6.4 inches and standard deviation of 1.8 inches. If a sample of 35 items are chosen at random, what is the probability the sample's mean length is greater than 6.1 inches?

$450

step-by-step explanation:

first, you have to multiply 150x2=300

next, you have to add 150+300= 450

80π/3 or about 83.775

step-by-step explanation:

since a cone is 1/3 of a cylinder, we need to find the base's area. since area = πr^2, we get 16π. then, multiplying this by 5, we get 80π. dividing by 3, since the cone's volume is 1/3 of that of a cylinder's, we get 80π/3.

hope this !
