Suppose that two graduating seniors, one a marketing major and one an accounting major, are comparing job offers. The accounting major has an offer for $45,000 per year, and the marketing student has an offer for $43,000 per year. Summary information about the distribution of offers follows:

Accounting: mean = 46,000 standard deviation = 1400Marketing: mean = 42,500 standard deviation = 1200Then calculate the appropriate z scores. Round the answers to two decimal places.

a)

z = -0.71

b)

z = 0.42

Step-by-step explanation:

Z score is the number of standard deviations by which a value is above or below the mean score of the observed population. Values above the mean have positive Z scores, while those below the mean have negative Z scores.

The Z score is given by the equation:

a)

Given that:

For accounting: mean (μ) = 46,000 standard deviation (σ) = 1400

Since the accounting major has an offer for $45,000 per year

b)

Given that:

For Marketing: mean (μ) = 42,500 standard deviation (σ) = 1200

Since the marketing student has an offer for $43,000 per year

you can first factor out the n to get n(1+5). we know that 1+5 is 6, so we just have 6n.

answer: b. f(x) = (x + 2)^3 (x^2 - 7x + 3)^4

step-by-step explanation:

polynomials always have as many roots as their order. this is a 4th order polynomial- hence 4 roots!

complex roots of polynomials always come in pairs. the quadratic equation has the "+/-" in that will alwaysgenerate m+ni amd m-ni, so 7-2i must be a root of this polynomial equation.

the order of the numerator and denominator are both 2. so the horizontal asymptote is y=a2/b2 =7

verticle asymptotes are the forbidden x-values. f(x) becomes undefined at x=-3 because this value will cause a zero denominator.

a graph of r(x) will have vertical asymptotes at ±1 because these values will make the denominator zero. so the domain of the function cannot include ±1.

you 're wlecome! : )
