Answer: 20,020 ways

Step-by-step explanation:

Given : The number of faculty members = 11

The number of students =14

Total number of people are eligible to serve on the committee = 11+14=25

Now, the number of ways to form a committee consisting of 2 faculty members and 3 students is to be formed will be :-

^{11}C_{2}\times^{14}C_{3}

=\dfrac{11!}{2!9!}\times\dfrac{14!}{3!11!}=20020

Hence, The committee can be formed in 20,020 ways .

Which statement is always true?
Marina CMI [18]

Answer:

b) the product of two rational numbers rational

Step-by-step explanation:

A rational number can be defined as a number that has a numerator or a denominator. This means that a rational number exists as a fraction e.g 2/3, 6/7 e.t.c

An irrational number is a number that cannot exist as a fraction or as a ration between two numbers. Irrational number can be expressed in decimal format that continues and keeps continuing.

And example of an irrational number is : √2, √5, √7 e.t.c

We were given 4 options above.

a) the product of two irrational numbers is irrational

The product of two irrational number can give us both a rational number and an irrational number. For example,

√2 × √7 = √ 14 which is an irrational number.

√5 × √5 = √ 25 = 5 which is a rational number.

Therefore Option A is not always true as the product of two irrational number can given both irrational and rational numbers.

b) the product of two rational numbers rational

Option b is always true and this is correct. For example

5× 5 = 25 which is a rational number

5/6 × 1/2 = 5/12 which is a rational number.

c) the sum of two rational numbers is irrational.

Option c is a wrong or false option and statement. This is because the sum of two rational numbers would always give you a rational number and not an irrational number.

For example: 5+ 4 = 9 (rational number)

2/5 + 1/5 =3/5 ( rational number)

Hence option c is a wrong option

d) the sum of an irrational number and a rational number is rational

Option d is an incorrect option and statement.

This is because, the sum of an irrational number and a rational number gives us an irrational number.

For example: 2(rational number ) + √2 (Irrational number) = 3.4142135624(Irrational number)

From the above explanation , we can see and observe that the only correct option and statement that is ALWAYS true is :

Option b) "the product of two rational numbers rational"

in a certain game, a fair die is rolled and a player gains 20 points if the die shows a 6. if the die does not show a 6, the pla
BaLLatris [955]

The expected gain or loss is an illustration of mean and expected values.

The expected total gain is 83 points

The given parameters are:

  • Addition of 20 points for rolling a 6
  • Removal of 3 points for not rolling a 6

The probability of rolling a 6 in a fair die is 1/6.

The probability of not rolling a 6 in a fair die is 5/6.

So, the expected gain in each game is:

\mathbf{E(x) = 20 \times \frac 16 - 3 \times \frac 56}

\mathbf{E(x) = \frac{20}6 -  \frac{15}6}

Take LCM

\mathbf{E(x) = \frac{5}6}

\mathbf{E(x) = 0.83}

The number of games is 100.

So, the expected gain is:

\mathbf{Gain = 100 \times 0.83}

\mathbf{Gain = 83}

Hence, the expected total gain is 83 points

What is slope of the line -3y=8x -5?
professor190 [17]
When finding the slope of a line you need to get it into the form y=mx+b, m being your slope. So if you divide your entire problem by -3 to isolate your y, you get y=-8/3x+5/3. This means that -8/3 will be your slope.
