Step-by-step explanation:

Answer:

The given data can be written in the form of an AP, where n is the number of songs Hailey downloads

song_bill(n) = 14 + n(1.50)

Money Hailey has to pay after downloading 40 songs:

n = 40

song_bill(40) = 14 + 40(1.5)

song_bill(40) = 14  + 60

song_bill(40) = 74 dollars

Money Hailey has to pay after downloading ss songs:

n = ss

song_bill(ss) = 14 + ss(1.5)

song_bill(ss) = 14 + 1.5(ss) dollars

  [tex]P(A) =  \frac{1}{8}[/tex]

c

 [tex]P(B) = \frac{1}{4}[/tex]

d

[tex]P(C) = \frac{5}{16}[/tex]

Step-by-step explanation:

From the question we are told that

The number of True - False question is n = 4

The number of answers recorded are k = 4

Generally the outcomes in the sample space are 16 and they are listed below

[ FFFF] , [FFFT] , [FFTF] , [FFTT]

[FTFF] , [FTFT] , [FTTF], [FTTT]

[TFFF] , [TFFT] , [TFTF] , [TFTT]

[TTFF] , [TTFT],[TTTF] , [TTTT]

Generally from the list of the possible outcome we see that the number of outcome where the answers are the same is 2 i.e [TTTT] and [FFFF]

So the probability that all the answers are the same is mathematically represented as

[tex]P(A) = \frac{2}{16}[/tex]

=> [tex]P(A) = \frac{1}{8}[/tex]

Generally from the list of the possible outcome we see that the number of outcome where exactly one answer is true is 4 i.e [FFTF] , [FFFT],[TFFF] , [FTFF]

So the probability that exactly one of the four answers is "True." is mathematically represented as

[tex]P(B) = \frac{4}{16}[/tex]

=> [tex]P(B) = \frac{1}{4}[/tex]

Generally from the list of the possible outcome we see that the number of outcome where at most one of the four answers is true is 5 i.e [FTFF] , [FFFF] , [FFTF] , [FFFT] ,[TFFF]

So the probability that at most one of the four answers is mathematically represented as

[tex]P(C) = \frac{5}{16}[/tex]

The probabilities of all same, exactly one true, and most one of the four are true is 0.125, 0.25, and 0.3125 respectively.

Probability means possibility. It deals with the occurrence of a random event. The value of probability can only be from 0 to 1. Its basic meaning is something is likely to happen. It is the ratio of the favorable event to the total number of events.

A section of an exam contains four True-False questions.

A completed exam paper is selected at random, and the four answers are recorded.

Total event = 16

A.  The sample space will be shown in the table below.

[tex]\rm Sample \ space = 16 \ \begin{Bmatrix}FFFF & FFFT & FFTF & FFTT \\FTFF & FTFT & FTTF & FTTT \\TFFF & TFFT & TFTF & TFTT \\TTFF & TTFT & TTTF & TTTT\end{Bmatrix}[/tex]

B.  The probability that all the answers are the same will be.

Favorable event = 2 ={(TTTT, FFFF}

Then we have the probability,

[tex]\rm P(B) =\dfrac{2}{16} =\dfrac{1}{8} = 0.125[/tex]

C.  The probability that exactly one of the four answers is "True".

Favorable event = 4 {(FFFT, FFTF, FTFF, TFFF}

Then we have the probability,

[tex]\rm P(C) =\dfrac{4}{16} =\dfrac{1}{4} = 0.25[/tex]

D.  The probability that at most one of the four answers is "True".

Favorable event = 5 {(FFFF, FFFT, FFTF, FTFF, TFFF}

Then we have the probability,

[tex]\rm P(D) =\dfrac{5}{16} =0.3125[/tex]

Answer:

84 miles in 12 hour

Step-by-step explanation:

12/4 = 3

3*28=84

Answer:

84 miles.

Step-by-step explanation:

First, find the rate of miles travel per hour.  It is given that the boat covers 28 miles in 4 hours. Simply divide 28 with 4:

28/4 = 7

The boat covers 7 miles per hour.

Now, multiply 12 hours with 7:

12 hours x 7 miles per hour = 84 miles per 12 hours.

84 miles is your answer.

Answer:

5=148 and 8=32

Step-by-step explanation:

For this equation we know since the lines are parelle that they will produce the same angle degrees.

so 2,4,6,and 8 are all 32

if we subtract 180 (the dregree of a stright line) from 32 we get 148

so 148 is for 1,3,5, and 7

Answer:

Step-by-step explanation:

Given the simultaneous equation

4x-5y+16 =0  ....... 1

2x+y-6 =0  ...... 2

Let us solve to get the variable x and y:

The equation becomes

4x-5y =-16   ........ * 1

2x+y =6 ...... *2

Using Elimination method

Multiply eqn 1 by 1 and eqn 2 by 2

4x-5y =-16

4x+2y =12

Subtract resulting equation

-5y-2y = -16-12

-7y = -28

solve for y

-7y/-7 = -28/-7

y = 4

Substitute y = 4 into equation 2 to get x

2x+y =6

2x + 4 = 6

2x = 6-4

2x = 2

x = 2/2

x = 1

hence x is 1, y is 4
