Due to the economy and not wanting to eliminate any jobs, all state employees were asked to accept a 4.5% reduction in their sal
jeka94

Answer: The secretary's salary prior to the reduction was $42,000.

Step-by-step explanation:

Hi, to answer this question we have to write an equation:

The original secretary's salary (x) multiplied by the percentage reduction in decimal form (4.5/100) must be equal to the amount of the reduction (1890)

Mathematically speaking:

x (4.5/100)= 1890

Solving for x:

x (0.045)= 1890

x = 1890/ 0.045

x = 42,000

The secretary's salary prior to the reduction was $42,000.

The number of days that homes stay on the market before they sell in Houston is bell-shaped with a mean equal to 56 days. Furthe
antoniya [11.8K]

Answer:

D. 8

Step-by-step explanation:

We have been given that the number of days that homes stay on the market before they sell in Houston is bell-shaped with a mean equal to 56 days. Further, 95 percent of all homes are on the market between 40 and 72 days.

As per empirical rule 95% of the data on bell curve lies between 2 standard deviations of mean.

So we can set an equation as:

72-56=2\sigma or

40-56=-2\sigma

16=2\sigma

\frac{16}{2}=\frac{2\sigma}{2}

8=\sigma

40-56=-2\sigma

-16=-2\sigma

\frac{-16}{-2}=\frac{-2\sigma}{-2}

8=\sigma

Therefore, the standard deviation for our given data is 8 and option D is the correct choice.
