A company wants to evaluate its attrition rate, in other words, how long new hires with the company. Over the years, they have e

stablished the following probability distribution.
Let X = the number of years a new hire will stay with the company.
Let P(x) = the probability that a new hire will stay with the company x years.
1. Complete Table using the data provided.
x p(x)
0 0.12
1 0.18
2 0.30
3 0.15
4
5 0.10
6 0.05

Answer:

2.) 0.10 (3.) 0.10 (4.) 2.43

Step-by-step explanation:

Given that:

x p(x)

0 0.12

1 0.18

2 0.30

3 0.15

4

5 0.10

6 0.05

X : __0__ 1 ___ 2 ___ 3 _____ 4 ____ 5 ____ 6

p(x):0.12_0.18_0.30_0.15__0.10___0.10 ___0.05

Σ of p(x) = 1

(0.12 + 0.18 + 0.30 + 0.15 + x + 0.10 + 0.05) = 1

0.9 + x = 1

x = 1 - 0.9

x = 0.1

2.)

P(x = 4) = 0.10

3.)

P(x = 5) = 0.10

4.)

Σ(x * p(x)) :

(0*0.12) + (1*0.18) + (2*0.3) + (3*0.15) + (4*0.1) + (5*0.1) + (6*0.05) = 2.43

Write a set of three different numbers that have a GCF of 16.
Lady_Fox [76]
To be a gcf of a number, they have to all divide by it evenly
so if 2 is a gcf of 12 and 6 then 6/2=3 =whole and 12/2=6=whole so

therefor we can just introduct other factors which are not equal
just multiply 16 by 3 prime numbers or different numbers
16 times 2 =32
16 times 3=48
16 times 5=80

and that is an example

Is the given ordered pair a solution to the equation? <br><br><br> y=2x+7;(-2, 3)
iren2701 [21]

Answer:

The answer to your question is: Yes, it is a solution

Step-by-step explanation:

           

Point  (-2, 3)

                         Line:            y = 2x + 7

Process, replace the point in the line

                                          3 = 2(-2) + 7

                                          3 = -4 + 7

                                          3 = 3

As we got that 3 equals 3, then the point given is a solution of the equation.

1. What is the constant of proportionality, k,<br><br><br> of Kevin's wage? Greg's? Savannah's?
Gala2k [10]

Answer:

Part a) The constant of proportionality of Kevin's wage is k=\$8.25\ per\ hour

Part b) The constant of proportionality of Greg's wage is k=\$9.00\ per\ hour

Part c) The constant of proportionality of Savannah's wage is k=\$9.50\ per\ hour

Step-by-step explanation:

See the attached figure to better understand the problem

we know that

A relationship between two variables, x, and y, represent a proportional variation if it can be expressed in the form y/x=k or y=kx

To find out the constant of proportionality k , divide the variable y (total earned) by the variable x (number of hours)

<em>Kevin's wage</em>

Take any point from the table

I take the point (2,16.50)

k=\frac{16.50}{2}=\$8.25\ per\ hour

<em>Greg's wage</em>

Take any point from the table

I take the point (3,27.00)

k=\frac{27.00}{3}=\$9.00\ per\ hour

<em>Savannah's wage</em>

Take any point from the table

I take the point (2,19.00)

k=\frac{19.00}{2}=\$9.50\ per\ hour
