Real world description to fit the expression -50 divided by 5

1 answer:

7 0

<span>Negative numbers generally refer to a fall, loss or a movement to the left. For the above expression, let us take it as a business loss. So -50 can mean a loss of $50. This amount is shared equally by 5 people. Divided by means shared by or distributed among. If 5 people share a loss of $50, each person'e loss will be $10. This is the same answer when we divide -50 by 5. Since it is a loss for each person, we should mark it as -10.</span>

What is 6x3/5 as a mixed number

Katen [24]

First, make 6 into an improper fraction.
6/1
Now multiply the numerators.
6x3=18
Now, the same with the denominators.
1x5=5
18/5
Now make it into a mixed number.
5x3=15
3 and...
18-15=3
3 and 3/5!!
Hope this helped!

The following probability distributions of job satisfaction scores for a sample of information

kodGreya [7K]

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.
