Answer:

the absolute value inequality in the form |x-b|c that has the solution set x≤−9 or x≥−5. lol jk

Step-by-step explanation:

|x−b|=c

Since we need three conditions that need to be met, we will opt for presenting three different expressions as a solution.

Case 1

One solution: x=−9

One expression that satisfies this condition is

(c = 0, b = -9 )

|x + 9|=0

|-9 + 9|=0

Case 2

All numbers such that x≤5

The solutions that satisfy this case can be found in the attached picture below, (they were obtained with a mathematical solver.)

Case 3

All numbers such that x≤-14

i pretty sure this is it.

The lengths of bolts in a batch are distributed normally with a mean of 3 cm and a standard

ValentinkaMS [17]

Answer:

0.8413 = 84.13% probability that a bolt has a length greater than 2.96 cm.

Step-by-step explanation:

Normal Probability Distribution:

Problems of normal distributions can be solved using the z-score formula.

In a set with mean $\mu$ and standard deviation $\sigma$ , the z-score 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 p-value, we get the probability that the value of the measure is greater than X.

Mean of 3 cm and a standard deviation of 0.04 cm.

This means that $\mu = 3, \sigma = 0.04$

What is the probability that a bolt has a length greater than 2.96 cm?

This is 1 subtracted by the p-value of Z when X = 2.96. So

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

$Z = \frac{2.96 - 3}{0.04}$

$Z = -1$

$Z = -1$ has a p-value of 0.1587.

1 - 0.1587 = 0.8413

0.8413 = 84.13% probability that a bolt has a length greater than 2.96 cm.
