Answer: The correct option is (B.) ≤.

Step-by-step explanation: We are given to complete the following statement by choosing the right option from the given choices:

12.1324 ? √175.

At first, we need to find the value of √175 and then we have to compare with 12.1324.

We have

$\sqrt{175}=\sqrt{7\times25}=\sqrt{7\times 5^2}=5\sqrt7=5\times 2.64571=13.2285...$

Therefore,

√175 = 13.2285....

Comparing with 12.1324..., we can see that 12.1324... is less than 13.2285...

Thus, the complete statement is

12.1324... ≤ 13.2285...

Option (B) is CORRECT.

At a fixed operating setting, the pressure in a line downstream of a reciprocating compressor has a mean value of 950 kPa with a

prisoha [69]

Answer:

4.75% probability that the line pressure will exceed 1000 kPa during any measurement

Step-by-step explanation:

Problems of normally distributed samples are 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:

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

The Z-score measures how many standard deviations the measure is from the mean. 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, that is, the percentile of X. Subtracting 1 by the pvalue, we get the probability that the value of the measure is greater than X.

In this problem, we have that:

$\mu = 950, \sigma = 30$
