A new extended-life light bulb has an average life of 750 hours, with a standard deviation of 50 hours. If the life of these lig
Yuki888 [10]

Answer:

99.7% of the distribution will be between 600 hours and 900 hours.

Step-by-step explanation:

The Empirical Rule states that, for a normally distributed random variable:

68% of the measures are within 1 standard deviation of the mean.

95% of the measures are within 2 standard deviation of the mean.

99.7% of the measures are within 3 standard deviations of the mean.

In this problem, we have that:

Mean = 750

Standard deviation = 50

What percent of the distribution will be between 600 hours and 900 hours?

600 = 750 - 3*50

600 is 3 standard deviations below the mean

900 = 750 + 3*50

900 is 3 standard deviations above the mean

By the Empirical Rule, 99.7% of the distribution will be between 600 hours and 900 hours.

Combine like terms to simplify the expression: {\dfrac{2}{5}k-\dfrac35+\dfrac{1}{10}k} 5 2 ​ k− 5 3 ​ + 10 1 ​ kstart fraction,
Fed [463]

Given:

The expression is

{\dfrac{2}{5}k-\dfrac35+\dfrac{1}{10}k}

To find:

The simplified form of given expression.

Solution:

We have,

{\dfrac{2}{5}k-\dfrac35+\dfrac{1}{10}k}

On combining like terms, we get

=\left(\dfrac{2}{5}k+\dfrac{1}{10}k\right)-\dfrac{3}{5}

Taking LCM in the parenthesis, we get

=\left(\dfrac{4k+k}{10}\right)-\dfrac{3}{5}

=\left(\dfrac{5k}{10}\right)-\dfrac{3}{5}

=\dfrac{k}{2}-\dfrac{3}{5}

Therefore, the simplified form of the given expression is \dfrac{k}{2}-\dfrac{3}{5}.
