Basically any two numbers whose product is 44^2 = 1936. 
so 16×121 = 1936
so the pair is 16 and 121

lys-0071 [83]

The magnitude of the second atom relative to the first = 10⁻¹¹ / 10⁻¹³ = 100

<h3>Equation</h3>

An equation is an expression used to show the relationship between two or more variables or numbers.

The magnitude of the second atom relative to the first = magnitude of second atom / magnitude of first atom

The magnitude of the second atom relative to the first = 10⁻¹¹ / 10⁻¹³ = 100

My Notes A large manufacturing plant uses lightbulbs with lifetimes that are normally distributed with a mean of 1600 hours and
Evgen [1.6K]

Answer:

The bulbs should be replaced each 1436.9 hours.

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 = 1600, \sigma = 70

How often should the bulbs be replaced so that no more than 1% burn out between replacement periods?

This is the first percentile of hours. So it is X when Z has a pvalue of 0.01.

So it is X when Z = -2.33.

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

-2.33 = \frac{X - 1600}{70}

X - 1600 = -2.33*70

X = 1436.9

The bulbs should be replaced each 1436.9 hours.
