Answer: $0.28 per pencil

Step-by-step explanation: Unit price means the cost per unit, in this case the cost per per pencil.

Since we know that it costs $2.24 for 8 pencils, to find the cost for 1 pencil, we need to divide 8 into $2.24.

I provided an image with the division. *You can also just use a calculator.*

So, 8 divides into 2.24 0.28 times.

Therefore, each pencil costs 28 cents which means that the unit price is 28 cents per pencil.

Answer:

There is a 0.82% probability that a line width is greater than 0.62 micrometer.

Step-by-step explanation:

Problems of normally distributed samples can be solved using the z-score formula.

In a set with mean $\mu$ and standard deviation $\sigma$ , the zscore of a measure X is given by

$Z = \frac{X - \mu}{\sigma}$

After finding the Z-score, we look at the z-score table and find the p-value associated with this z-score. This p-value is the probability that the value of the measure is smaller than X. The sum of the probabilities is decimal 1. So 1-pvalue is the probability that the value of the measure is larger than X.

In this problem

The line width used for semiconductor manufacturing is assumed to be normally distributed with a mean of 0.5 micrometer and a standard deviation of 0.05 micrometer, so $\mu = 0.5, \sigma = 0.05$ .
