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?

2 over 5

step-by-step explanation:

the 2: 3 ratio is the length of the ac segment to the cb segment total length. this implies that the ratio between segment ac length and segment ab length is 2: 5. point c is 2/5 from a to b, so the required fraction is 2/5.

d. it is a convex pentagon because it has five sides and none of the sides would extend into the inside of the polygon.

step-by-step explanation:

$450 i think. hope this ☺

the ratios are reciprocals im positive

step-by-step explanation:

they are all positive numbers so it wouldn't be the other ones
