How many ways are there to assign six jobs to five different employees if every employee is assigned at least one job?
NARA [144]

Answer:

There are 1800 different ways.

Step-by-step explanation:

A permutation give as the total ways in which we can organized a group of elements where the order is important. So, the  permutation of n elements when all of them are not different is calculate as:

\frac{n!}{n1!n2!...nk!}

Where k is the number of elements that are different, n1, n2, ... nk are the number of times that very element appears and n is equal to n1+n2+...nk.

In this case we have 5 differents and general ways to assign six jobs to five different employees:

1. the first employee receive 2 jobs

2. the second employee receive 2 jobs

3. the third employee receive 2 jobs

4. the fourth employee receive 2 jobs

5. the fifth employee receive 2 jobs

Then, if the first employe receive 2 jobs, its mean that we have six people to permutate and the first person appears two times.

So the permutation of this 6 element in which one is repeat 2 times is calculate as:

\frac{6!}{2!*1!*1!*1!*1!*1!}=360

Therefore, there are 360 ways to organized five different employees into 6 jobs where the first person can receive two jobs.

For the other 4 options we can made the same calculation, so the total number of ways that we can organized five employees in six jobs are calculate as:

360*5=1800

Finally there are 1800 different ways.

The measure of central angle XYZ is 3 pie / 4 radians.
Elena L [17]

Answer: 96\pi\text{ units}^2

Step-by-step explanation:

From the given picture, it can be seen that the radius of the circle = 16 units

Also, the measure of central angle XYZ =\dfrac{3}{4}\pi radians

The area of sector with radius r and angle x radian is given by :-

\text{Area of sector}=\dfrac{1}{2}r^2\ x

Now, the area of the shaded sector is given by :-

\text{Area of the shaded sector}=\dfrac{1}{2}(16)^2\dfrac{3}{4}\pi\\\\\Rightarrow\text{Area of the shaded sector}=96\pi\text{ units^2}

The function f(x)=2x−5 is a linear function. Let g(x) represent f(x) after a horizontal translation 3 units to the right.
Ray Of Light [21]

Answer:

the equation of g(x) is, g(x) = 2x-11  

Step-by-step explanation:

The transformation of the function is defined as:

g(x)=f(x+b)

where, b represents the horizontal shift.

if b> 0 then, the function f(x) shifts b units left and if b< 0 ; then the function shifts b units right  

As per the statement:

The function f(x)=2x−5 is a linear function.

It is given that:

g(x) represent f(x) after a horizontal translation 3 units to the right.

⇒g(x) =f(x-3)

then

g(x) = 2(x-3)-5

⇒g(x) = 2x-6-5

⇒g(x) = 2x-11

Therefore, the equation of g(x) is, g(x) = 2x-11

Bumek [7]
<span> Here are the steps, you fill in the missing parts.
A. The given ratio is:
2 adults per 9 students or the fraction 2/9
Now put that fraction 2/9=x/171 in other words, how many adults (x) for 171 students?
can you cross multiply and get 9x=342
and solve for x?

How you have the number of students and the number of adults.

B. for food multiply $6 times the total number of people.

C. for tickets multiply 4.50 times the student number and
7.50 times the adult number.

D. for the bus parking fee multiply .04 times you total answer in part C.

Now add up the food, tickets, bus parking and I think you have what Mr. Williams has to budget. </span>
