Mathematics
1 answer:
kodGreya [7K]3 years ago
4 0

Answer:

a. 4.05 b. 3.84 c. 1.2475 and 1.1344 d. 1.1169 and 1.0651  e. We can say that the overall job satistaction of senior executives and middle managers is about 4; however, there is more variability in the job satisfaction for senior executives than in the job satisfaction for middle managers.

Step-by-step explanation:

a. (1)(0.05)+(2)(0.09)+(3)(0.03)+(4)(0.42)+(5)(0.41) = 4.05

b. (1)(0.04)+(2)(0.1)+(3)(0.12)+(4)(0.46)+(5)(0.28) = 3.84

c. We compute the variances as follow: [(1)^2(0.05)+(2)^2(0.09)+(3)^2(0.03)+(4)^2(0.42)+(5)^2(0.41)] - 4.05^2 = 1.2475 and [(1)^2(0.04)+(2)^2(0.1)+(3)^2(0.12)+(4)^2(0.46)+(5)^2(0.28)]-3.84^2 = 1.1344

d. The standard deviation is the squared root of the variance, therefore, we have \sqrt{1.2475} = 1.1169 and \sqrt{1.1344} = 1.0651

e. The expected value of the job satisfaction score for senior executives is very similar to the job satisfaction score for middle managers. We can say that the overall job satistaction of senior executives and middle managers is about 4; however, there is more variability in the job satisfaction for senior executives than in the job satisfaction for middle managers.

Answer:

Step-by-step explanation:

Given function is,

f(x) = \frac{3x-2}{x-2}

Vertical asymptote of the function,

x = 2

Horizontal asymptote of the function,

y = 3

No oblique asymptotes.

Therefore, graph having vertical and horizontal asymptotes as x = 2 and y = 3 will be the correct graph as attached.
