Answer:

The z score for bolt of diameter 18.12 mm is 1.20.

Step-by-step explanation:

Let X = diameter of bolts.

It is provided that the random variable X follows a Normal distribution with mean, μ = 18 mm and standard deviation, σ = 0.10 mm.

A z-score is a standardized score, a numerical, that defines how far a data value from the mean.

The distribution of z-scores is defined by the Standard Normal distribution.

$Z\sim N(0, 1)$

The formula to compute the z-score is:

$z=\frac{x-\mu}{\sigma}$

The value of the diameter of a bolt is, x = 18.12 mm.

Compute the z-score for this value as follows:

$z=\frac{x-\mu}{\sigma}=\frac{18.12-18}{0.10}=\frac{0.12}{0.10}=1.20$

Thus, the z score for bolt of diameter 18.12 mm is 1.20.

Answer:

1.67

Step-by-step explanation:

after the decimal we have the

tens

hundreths

thousanths

(usually math doesn't ask you to go farther than the thousanths place)

because 15/9 is 1.66666, you will go to the hundreths place and round that six. Six is one more than five so it gets rounded up. That changes the decimal to 1.67. You do not change it to 1.7, because it asked you to round to the nearest hundred not the nearest tens
