Answer:

165

Step-by-step explanation:

In 165 ways i can select 3 books to bring on vacation from a group of 11 books.

A combination is when you choose data from a group without any order or sequence. If the group of data is relatively lesser, you can calculate the number of possible combinations.

According to the question

Select 3 books to bring on vacation from a group of 11 books.

By using combinations formula

[tex]^{n} C _{r}=\frac{n!}{r!(n-r)!}[/tex]

[tex]^{11} C_{3}[/tex] = [tex]\frac{11!}{3!(11-3)!}[/tex]

= [tex]\frac{11.(10)(9)(8!)}{3!.8!}[/tex]

Cancelling out 8! from denominator and numerator

= [tex]\frac{11(10)(9)}{3(2)(1)}[/tex]

= 165

Thus, In 165 ways i can select 3 books to bring on vacation from a group of 11 books.

Answer: -5 is equal to x

Step-by-step explanation:

This is since you just make y = 0 to solve, so

0=x+5

= -5=x

Answer:

x=-8 and y=2 / x=-5 and x=5

Step-by-step explanation:

put x as 0 to find y

y=1÷4x+2

y=1÷4×0+2

y=0+2

y=2

put y as 0 to find x

y=1÷4x+2

0=1÷4x+2

-2+0=1÷4x

-2=1÷4x

1÷4x=-2

1x=-2×4

x=-8

y=x+5

0=x+5

x=-5

y=0+5

y=5

Answer:

3x2+15x=18

Step 1: Subtract 18 from both sides.

3x2+15x−18=18−18

3x2+15x−18=0

Step 2: Factor left side of equation.

3(x−1)(x+6)=0

Step 3: Set factors equal to 0.

x−1=0 or x+6=0

x=1 or x=−6

Answer:

A

I worked them out myself so if their wrong uh please don't get mad I tried my best.

Step-by-step explanation:

3x (2) + 15x = 18                               3x (2) + 15x = 18

6x + 15x = 18                                     6x + 15x = 18  

-6x + -6x = 18                                            -18     -18

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

0 + 9x = 18                                            6x + -3 = 0

   ------  -------                                         -3 +  -3

      18  18                                           --------------------

          x = 2                                              -3 + 0

                                                                    X = -3

97 divided by 12

Based on the circumstances of the 100 workers and their union membership, the probabilities are:

Number of people with jobs in new companies:

= 14 + 10

= 24

There are 24 people who have found a new job and out of them, 14 are in a union. The probability here is therefore:
= 14 / 24

= 0.583

The number of people in a Union is:
= 39 + 14 + 6 + 2

= 61 people

Number of union people that have been unemployed is 2.

The probability here is therefore:

= 2 / 61

= 0.033.

Step-by-step explanation:

Answer: x= -2/3y+5/3

Step-by-step explanation:

Let's solve for x.

3x+2y−5=0

Step 1: Add -2y to both sides.

3x+2y−5+−2y=0+−2y

3x−5=−2y

Step 2: Add 5 to both sides.

3x−5+5=−2y+5

3x=−2y+5

Step 3: Divide both sides by 3.

3x/3=-2y+5/3

x= -2/3y+5/3

Answer:

500 students appeared in the examination.

Step-by-step explanation:

Each event represents a set in the Venn diagram, and we use it to find the desired values.

I am going to say that:

Event A: Passed in English.

Event B: Passed in Science.

80% passed in English

This means that [tex]P(A) = 0.8[/tex].

75% passed in Science

This means that [tex]P(B) = 0.75[/tex]

5% failed in both subjects.

This means that 100% - 5% = 95% passed at least one of these subjects, so [tex]P(A \cup B) = 0.95[/tex].

Proportion that passed both subjects:

This is [tex]P(A \cap B)[/tex]

These percentages are related by the following equation:

[tex]P(A \cap B) = P(A) + P(B) - P(A \cup B)[/tex]

So

[tex]P(A \cap B) = 0.8 + 0.75 - 0.95 = 0.6[/tex]

Number of students in class:

60% of the total number t passed both subjects. This is equals to 300. So

[tex]0.6t = 300[/tex]

[tex]t = \frac{300}{0.6}[/tex]

[tex]t = 500[/tex]

500 students appeared in the examination.

Answer:

1/3 = 0.3333 = 33.33% experimental probability of rolling a 9​.

Step-by-step explanation:

The experimental probability is given by the number of desired outcomes divided by the number of total outcomes, after a number of experiments is made.

In this question:

Cube rolled 78 times.

9 appeared 26 times

26/78 = 1/3 = 0.3333 = 33.33% experimental probability of rolling a 9​.
