Answer 1

Answer:

The answer is D $3.35

Step-by-step explanation:

[tex]2.35 + .25x = 1.75 + .40x \\ 2.35 = 1.75 + .40x - .25x \\ 2.35 = 1.75 + .15x \\ 2.35 - 1.75 = .15x \\ .60 = .15x \\ \frac{.60}{.15} = x \\ x = 4[/tex]

[tex]2.35 + .25(4) = 2.35 + 1 = 3.35[/tex]

There are 15 tiles in a bag. Of these, 7 are purple, 5 are black and the rest are white.
Event A = drawing a white tile on the first draw
Event B = drawing a purple tile on the second draw
If two tiles are drawn from the bag one after the other and not replaced, what is P(B|A) expressed in simplest form?

A. 1/5
B. 1/3
C. 7/15
D. 1/2

Answers

Answer: C.

Step-by-step explanation: If I am wong I am sorry !

Probability of drawing two tiles from the bag one after the other and not replaced that is P(B/A) is equals to [tex]\frac{1}{2}[/tex].

What is probability?

" Probability is defined as the ratio of number of favourable outcomes to the total number of outcomes."

Formula used

Conditional probability ' P(B/A)' = P(A∩B) / P(A)

According to the question,

Total number of tiles = 15

Number of while tiles  represented by 'A' = 3

Number of purple tiles represented by 'B' = 7

Number of black tiles= 5

Total number of outcomes = 15 × 14

                                              = 210

Favourable outcome for A = 3 × 14

                                            = 42

Favourable outcomes for A∩B = 3 × 7

                                                   = 21

Probability of A

'P(A)' =  [tex]\frac{42}{210}[/tex]

Probability of A∩B

'P(A∩B)' = [tex]\frac{21}{210}[/tex]

Substitute the value in the conditional probability we get,

Probability for P(B/A) = [tex]\frac{\frac{21}{210}}{\frac{42}{210} }[/tex]

                                     = [tex]\frac{1}{2}[/tex]

Hence, Option(D) is the correct answer.

There are 130 people in a sport centre.

68 people use the swimming pool.
60 people use the track.
25 people use the gym and the pool.
30 people use the pool and the track.
19 people use the gym and the track.
6 people use all three facilities.
A person is selected at random.
What is the probability that this person doesn't use any facility?

Answers

The probability that this person does not make use of the facility is 7/130

How to solve for the probability

61+68+60 - 25-28-19 + 6

= 123

The total number of person in the sport center is given as 130

We have 130 - 123 = 7

This means that there are a total of 7 persons that do not make use of this facility.

Hence the probability of a person not using the facility is 7/130

Answer: 8.3

Explanation:

The mean is the average of a data set; it is the number that falls directly in the middle of the data set.

The formula to find the average is: a=sum of terms/ number of terms.

Therefore, we just add up all the values in the data set and divide by how many numbers there are.

3+9+10+10+4+10+10+10/8 = 8.25. We added up all the numbers and then divided by how many numbers there were, which was 8.

8.25 rounded to the nearest tenth is 8.3.


Your answer is 8.3
