Answer:

a

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

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

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

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

b

  [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:

Option (3)

Step-by-step explanation:

If the two ratios are equivalent then the value of the ratios will be equal.

[tex]\frac{x_1}{y_1}=\frac{x_2}{y_2}[/tex]

Option (1)

[tex]\frac{11}{12}=\frac{44}{46}[/tex]

Simplified form of the fraction [tex]\frac{44}{46}[/tex] is,

[tex]\frac{44}{46}=\frac{22}{23}\times \frac{2}{2}=\frac{22}{23}[/tex]

Therefore, [tex]\frac{11}{12}=\frac{22}{23}[/tex]

Which is not true,

Therefore, option (1) doesn't show the equivalent ratio.

Option (2)

[tex]\frac{36}{40}=\frac{4}{9}[/tex]

Simplified form of [tex]\frac{36}{40}[/tex] is,

[tex]\frac{36}{40}=\frac{9}{10}\times \frac{4}{4}=\frac{9}{10}[/tex]

Therefore, [tex]\frac{4}{9}= \frac{9}{10}[/tex]

Which is not true.

Therefore, option (2) doesn't show the equivalent ratio.

Option (3)

[tex]\frac{1.5}{3}=\frac{12}{24}[/tex]

Since simplified form of [tex]\frac{1.5}{3}[/tex] is,

[tex]\frac{1.5}{3}=0.5[/tex]

And simplified form of [tex]\frac{12}{24}[/tex] is,

[tex]\frac{12}{24}=0.5[/tex]

Therefore, [tex]\frac{1.5}{3}=\frac{12}{24}=0.5[/tex]

Option (3) shows the equivalent ratios.

Option (4)

[tex]\frac{8}{12}=\frac{4}{24}[/tex]

Since, [tex]\frac{8}{12}=\frac{2}{3}\times \frac{4}{4}=\frac{2}{3}[/tex]

And [tex]\frac{4}{24}=\frac{1}{6}\times \frac{4}{4}=\frac{1}{6}[/tex]

But [tex]\frac{2}{3}\neq \frac{1}{6}[/tex]

Therefore, equation in this option doesn't show the equivalent ratios.

Answer:

1. 6 to 2 and 9 to 3

2. Any ratio that is not equivalent to 3 to 1. For example, 4 to 11.

Answer: Eric earned $7

Step-by-step explanation:

Let's define:

R = money that Robert earned.

E = Money that Eric earned.

Now we want to find how much money did Eric earn.

We know that:

R = $10 = 2*E - $4

Whit this equation, we can find the value of E. So we must isolate the variable E in one side of the equation:

2*E = $10 + $4 = $14

E = $14/2 = $7

Eric earned $7

Answer:

y = |-x-1| + 8.

Step-by-step explanation:

A reflection across the y axis gives the equation y = |-x -1| + 7.

Then a translation up 1 unit gives the equation y = |-x-1| + 8.

Answer:

H - Triangle Z, Triangle X, Triangle Y

Step-by-step explanation:

Triangle X area = rad(66.5) cm^3 ≈ 8.155cm^3

Triangle Y area = 8.15cm^3

Triangle Z area = (17.5/2)cm^3 = 8.75cm^3

8.75cm^3 > 8.155cm^3 > 8.15cm^3

Therefore:

Triangle Z area > Triangle X area > Triangle Y area

The solution to the radical expression √36 is 6.

A radical expression is a mathematical expression that contains a radical symbol (√), which represents the square root (or nth root) of a number or variable. The radical symbol is typically followed by a number or expression inside a set of parentheses, which indicates what is being rooted.

The square root of 36 is a number that, when multiplied by itself, equals 36. In this case, we know that the number is 6, because 6 x 6 = 36.
