a committee consisting of 4 faculty members and 5 students is to be formed. every committee position has the same duties and voting rights. there are 7 faculty members and 13 students eligible to serve on the committee. in how many ways can the committee be formed?

Answers

C(7, 4) = 7! / (4!(7-4)!) = (7 * 6 * 5) / (3 * 2 * 1) = 35

and

C(13, 5) = 13! / (5!(13-5)!) = (13 * 12 * 11 * 10 * 9) / (5 * 4 * 3 * 2 * 1) = 1287

Multiply these two combinations since the faculty members and students are selected independently:

Total number of ways to form the committee = C(7, 4) * C(13, 5) = 35 * 1287 = 45,045

Therefore, there are 45,045 ways to form the committee consisting of 4 faculty members and 5 students.
To determine the number of ways to form the committee with 4 faculty members and 5 students, we need to calculate the combinations of faculty members and students separately and then multiply them together.

For faculty members:
There are 7 eligible faculty members, and we need to select 4 of them for the committee. This can be done using the combination formula:

C(7, 4) = 7! / (4!(7 - 4)!) = 35.

So, there are 35 ways to select 4 faculty members from the 7 eligible ones.

For students:
There are 13 eligible students, and we need to select 5 of them for the committee. Using the combination formula again:

C(13, 5) = 13! / (5!(13 - 5)!) = 1287.

Therefore, there are 1287 ways to select 5 students from the 13 eligible ones.

To form the committee, we multiply the number of ways to select faculty members by the number of ways to select students:

35 * 1287 = 44,895.

Hence, there are 44,895 ways to form the committee consisting of 4 faculty members and 5 students from the eligible candidates.

I know someone else responded but theres an easier way to solve this without multiplying anything.
Neg*neg=pos
1. Has two neg and two negs make a pos
2. Has 4 neg which will also make pos
3. Has 3 neg. The first 2 will cancel out and make a pos but the last one will make the answer neg
4. Would just be 0 because its multiplying 0 but without it it would be neg.
So the answer is the third one

Step-by-step explanation:

The scale factor is multiplied by the original figure's dimensions to give the dimensions of the second figure.

To go from 1.5 to 6, you multiply 1.5 by 4, so the scale factor is 4.

Also you can divide a linear dimension of of the image by the corresponding dimension of the original figure to find the scale factor.

10 POINTS PLEASE HELP the arthemitic mean of 5, 10, 15, and z is 20. what is z

Answers

Answer:

z = 50

Step-by-step explanation:

There are 4 numbers in total (5,10,15,z)

The mean is when you get the total of all the numbers and divide by how many there are

If you do the inverse then that means that 20 x 4 = total of all 4 numbers

80 = 15 + 10 + 5 + z

80 = 30 + z

z = 80 - 30

z = 50

What is the total surface area of the right regular pyramid with a square base?

Answers

Answer:....C. 106ft2

The lateral surface and the total surface areas of the prism are 96 in² and 2304 in² respectively.

What is surface area?

The surface area of a solid object is a measure of the total area that the surface of the object occupies.

Here,

Given is prism, we need to find the lateral surface and the total surface areas,

Lateral surface area = (perimeter of base) × length

Perimeter of base = 3 × 4 = 12 in

length = 8 in

The lateral surface area = 12 × 8 = 96 in²

Total surface area = (perimeter of base) × length × 2(base area)

= 96 × 2(3×4)

= 96 × 24

= 2304 in²

Hence, the lateral surface and the total surface areas of the prism are 96 in² and 2304 in² respectively.

Hans is saving money to buy a game. So far he has saved $24, which is three-fourths of the total cost of the game. How much does the game cost?

Answers

Answer: The game costs $ 32 if $24 is three-fourths of total cost of the game. It is solved by making a mathematical equation containing fractions.

Step-by-step explanation:

Let's assume total cost of the game is $Y,

We know that three-fourths of Y is $24.

so we get the following mathematical equation

3/4 x Y= 24

Multiplying with 4/3 on both sides of the equation,we get

(4/3) x (3/4) x Y= 24 x (4/3)

since (4/3 x 3/4 =1), we get the equation

Y=24 x (4/3) =96/3 =32

Therefore, the cost of the game is $32

https://brainly.com/question/30340082

Answer: The total cost of the game is $32.

Step-by-step explanation:

Let's assume the total cost of the game is represented by the variable "x".

Given information says that, Hans has saved $24, which is three-fourths (3/4) of the total cost of the game. We can set up the following equation:

3/4 * x = $24

To find the value of "x," we can solve this equation:

3/4 * x = $24

To isolate "x," we can multiply both sides of the equation by the reciprocal of 3/4, which is 4/3:

x = ($24) * (4/3)

x = $32

Therefore, the total cost  is $32.
