At a certain company, the mentoring program and the community outreach program meet at the same time, so it is impossible for an

employee to do both. If the probability that an employee participates in the mentoring program is 0.51, and the probability that an employee participates in the outreach program is 0.21, what is the probability that an employee does the mentoring program or the community outreach program?

Answer:

0.72

Step-by-step explanation:

Let A be the event that an employee attends mentoring program and B the community outreach program.

Since they meet at the same time, so it is impossible for an employee to do both.

i.e. P(Aintersection B) =0

Given that

P(A) = 0.51\\P(B) = 0.21

the probability that an employee does the mentoring program or the community outreach program

=P(AUB) = P(A)+P(B)-P(AB)\\=0.51+0.21-0\\=0.72

Identify the domain of the function shown in the graph
Brut [27]

Using it's concept, the domain of the function shown in the graph is:

B. -6 \leq x \leq 6.

<h3>What is the domain of a function?</h3>

The domain of a function is the set that contains all possible input values for the function. In a graph, the domain is the set that contains all values of x.

From this graph, the function is defined for values of x between -6 and 6, hence the domain is given by:

B. -6 \leq x \leq 6.

−4x+7y+5=0<br> x−3y=−5<br> ​ <br><br> How many solutions does the system have?
xeze [42]

   

Solution:  

Using Substitution Method:

-4x+7y=-5   (Equation 1)

x-3y=-5       (Equation 2)

get the value of x from Equation 2

x=3y-5     (Equation 3)  

Put the value of x from Equation 3 in Equation 1

-4(3y-5)+7y=-5

-4(3y)+20+7y=-5

-12y+7y=-5-20

-5y=-25

Negative sign on both sides cancels each other

y=25/5

y=5

Putting value of y in equation 3

x=3(5)-5

x=15-5

x=10

Therefore,   [x,y]=[10,5]

Using Elimination Method

-4x+7y=-5   (Equation 1)

x-3y=-5       (Equation 2)

Multiply equation 2 with -4 in order to eliminate the x term

-4(x-3y)=-5*4

-4x+12y=20     (Equation 3)

Adding Equation 1 and 3

-4x+7y=-5    

-4x+12y=20    

+    -     = -   (Change Of Sign with x and y terms)

-----------------

0x-5y = -25

-5y=-25

y=5  

Substituting y’s value is Equation 1

-4x+7(5)=-5

-4x+35=-5

-4x=-40

Cancellation of negative sign on both sides

x=40/4

x=10

[x,y]=[10,5]
