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.

What does simplify mean in math?
Law Incorporation [45]
Simplify in Math, like in English, means to make as simple as possible - as "down to the roots as possible".

In the example = 36 + 10 . To simplify fully would be = 46 since that is as simple as it gets.

In algebra, to simplify fully might involve 14 = 2x, where to simplify fully would be to find x (x = 7)

What are the 2 numbers ?
gizmo_the_mogwai [7]

Answer:

Option D, 15 and 10

Step-by-step explanation:

<u>Step 1:  Convert the words into an expression</u>

A number is 5 less than 2 times another number.  Their sum is 25.

<em>2x - 5 = 25</em>

<em />

<u>Step 2:  Solve for x</u>

2x - 5 + 5 = 25 + 5

2x / 2 = 30 / 2

<em>x = 15</em>

<em />
