The Smith family has twins, Rob and Rachel. Both Rob and Rachel graduated from college two years ago, and each is now earning $50,000 per year. Rachel works in the retail industry, where the mean salary for executives with less than 5 years' experience is $35,000 with a standard deviation of $8,000. Rob is an engineer. The mean salary for engineers with less than 5 years' experience is $60,000 with a standard deviation of $5,000.

a. Compute the z values for both Rob and Rachel.

b. Comment on your findings

Solution Summary

The solution contains detailed explanation of finding the z values if the standard deviation of a population is given.

Problem: Please accept only if willing to explain.

C. Find t

An even function is defined as f(x) = f(-x), and an odd function has -f(x) = f(-x).
The domain of a function is the set of input data that keeps the function defined.
Determine if the function f(x) = -2x^2 * absolute value(-6x) is even, odd, or neither.
Find the average rate of change for the function f(x) = 4/(x+3) between t

Avogradro\'s number (6.022 x 10^23 atoms/mol) is a useful number that can be used to calculate a number of different values for compounds/elements. One important value is findingthe number of atoms in a specific mass of an element. The solution includes a general step-by-step method of findingthe number of atoms in a specifi

A store offers 2 models of scooter, a $29 model and a $33 one. An order was placed with a warehouse which totalled $2490 but the details had been lost. Can you tell the order clerk howl many of each model to send to the store?
