The quality control inspector of a factory manufacturing screws found that the samples of screws are normally distributed with a mean length of 5.5 cm and a standard deviation of 0.1 cm. If the distribution is normal, what percent of data lies between 5.3 centimeters and 5.7 centimeters?

d. bc = 12 and ef = 16

step-by-step explanation:

we are given that δabc : δdef such that .

also, it is given that

so, from the options, we need that .

a.

b.

c.  

d.

as, we can see that only option d gives the same ratio as i.e. .

hence, the possible lengths are bc = 12 and ef = 16.

the answer is a

step-by-step explanation:

because if you put 1 in to the square root of x it equals 300.

answer:

125 yards

explanation:
