Ellen takes a multiple-choice quiz that has 4 questions, with 3 answer choices for each question. What is the probability that she will get exactly 1 answer correct by guessing? Probabilities should be entered as fractions in simplest form, decimals rounded to the nearest thousandth, or percents rounded to the nearest tenth.

Answers

Answer: The probability is  32/81, or  0.395 in decimal form

Step-by-step explanation:

Each question has 3 answers.

one of the answers is correct, and 2 are incorrect.

Then the probability of selecting at random the correct answer, is equal to the quotient between the number of correct answers and the total number of answers, this is:

p = 1/3.

Then the probability of answering wrong is:

q = 1 - 1/3 = 2/3.

Now, we want to find the probability of answering exactly one question correctly.

Let's suppose that Ellen answers correctly the first question, and incorrectly the other 3.

then we have the probability 1/3 one time, and the probability 2/3 3 times.

And as we know, the joint probability will be equal to the product of the individual probabilities, this is:

P = (1/3)*(2/3)*(2/3)*(2/3).

But this is for the case where only the first one is answered correctly, we also have the cases where:

the 2nd is the only one answered correctly

the 3rd is the only one answered correctly

the 4th is the only one answered correctly.

Then we have 4 permutations, which means that the actual probability of answering only on question correctly is:

P' = 4*P = 4*(1/3)*(2/3)*(2/3)*(2/3) = (4*2*2*2)/(3*3*3*3) = 32/81 = 0.395

Answer:

x=7

Step-by-step explanation:

This problem uses vertical angles! I'm sure you know this but just in case I will explain. Whenever there are two angles that are across from each other in a junction of two straight lines, they are perfectly equal! In this problem, the angles 6x-7 and 4x+7 are the same angle, so those equations have to have the same answer. In order to solve it, you need to write the equations like this:

6x-7=4x+7

From there you can solve for x. I will write my process here:

2x-7=7

2x=14

x=7

Just writing those vertical angle equations as equalities of each other should give you the answers you are looking for!

The linear equation that represents the length of the candle will be L = - t + 7. And the slope will be - 1 inch per hour.

What is a linear equation?

A connection between a number of variables results in a linear model when a graph is displayed. The variable will have a degree of one.

The linear equation is given as,

y = mx + c

Where m is the slope of the line and c is the y-intercept of the line.

Ashley just lit a new candle and then let it burn all the way down to nothing.

Let L represent the length of the candle remaining unburned, in inches, t hours after the candle was lit.

The slope is calculated as,

m = (0 - 7) / (7 - 0)

m = - 1 inch per hour

Then the linear equation is given as,

L = - t + 7

The linear equation that represents the length of the candle will be L = - t + 7. And the slope will be - 1 inch per hour.

Write equivalent fractions for 2/3 and 3/5 using 15 as the common denominator.

Answers

The denominators of two or more fractions must have a common factor, and the calculation can be defined as follows:

Common denominator:

The common denominator should be determined if the denominators are different. Creating a commonality that is the product of the two different denominators is by far the most straightforward means of achieving this. To use it, divide each fraction's numerators by the opposing denominator.

              [tex]\to[/tex] [tex]\frac{2}{3} - \frac{3}{5}\\\\[/tex]

              [tex]\to[/tex] [tex]\frac{10-9}{15}\\\\[/tex]

              [tex]\to[/tex] [tex]\frac{10}{15} - \frac{9}{15}\\\\[/tex]

So, the common denominator value by using the 15 is equal to

 [tex]\to \frac{2}{3} : \frac{10}{15} : \frac{3}{5}: \frac{9}{15}[/tex]

The sum of the first (n) terms of the sequence is given by the formula (given below) . If this sequence is a geometric progression, find q. If this sequence is an Arithmetic progression, find d​

Answers

Answer:

We have established the following sequence

6, 12, 18,...

The given is the Arithmetic sequence with the nth term

[tex]a_n=6n[/tex]

d = 6 is a common difference.

Step-by-step explanation:

Given the formula

Sₙ = 3n² + 3n

Put n = 1 to determine the sum of the first term

S₁ = 3(1)² + 3(1)

S₁ = 3 + 3

S₁ = 6

As the sum of the first term includes the only first term, so

a₁ = 6

Put n = 2 to determine the sum of the two terms

Sₙ = 3n² + 3n

S₂ = 3n² + 3n

S₂ = 3(2)² + 3(2)

S₂ = 12 + 6

S₂ = 18

as

S₂ = a₁ + a₂

substituting S₂ = 18, a₁ = 6

18 = 6 + a₂

12 = a₂

so

a₂ = 12

Put n = 3 to determine the sum of the two terms

Sₙ = 3n² + 3n

S₃ = 3(3)² + 3(3)

S₃ = 27 + 9

S₃ =36

as

S₃ = a₁ + a₂ + a₃

substitutingS₃ =36, a₁ = 6, a₂ = 12

36 = 6+12+a₃

a₃ = 36-6-12

a₃ = 18

Thus,

a₁ = 6

a₂ = 12

a₃ = 18

Therefore, the sequence becomes

a₁, a₂, a₃,...

6, 12, 18,...

Let us check the common difference 'd' between the adjacent terms

d = 12 - 6 = 6

d = 18 - 12 = 6

As the common difference 'd' between adjacent terms is the same, therefore the sequence is Arithmetic.

Thus,

d = 6

Furthermore, the nth term of the Arithmetic sequence can be defined as

[tex]a_n=a_1+\left(n-1\right)d[/tex]

substituting d = 6 and a₁ = 6

[tex]a_n=6\left(n-1\right)+6[/tex]

[tex]a_n=6n[/tex]

A freezer can be bought on hire purchase by making a desposiy of 15% of the cash price which is $2975 the interest which is 20% of the outstanding balance is charged the amount payable is paid in 12 monthly instalements.Calculate the freezer

Answers

Answer: See explanation

Step-by-step explanation:

a. The deposit

= 15% × $2975

= 15/100 × $2975

= 0.15 × $2975

= $446.25

b. The hire purchase price

Outstanding balance = $2975 - $446.25 = $2528.75

20% of outstanding balance

= 20% × $2528.75

= 0.2 × $2528.75

= $505.75

Hire purchase price

= $2975 + $505.75

= $3480.75

c. The difference the hire purchase price and cash price

= $3480.75 - $2975

= $505.75

d. The difference as a percentage of the cash price.

= ($505.75 / $2975) × 100

= 0.17 × 100

= 17%

The graph that shows the solutions to the inequality is the last graph.

How to solve the given inequality?

Here we have the inequality:

-3.55g ≤ -28.4

To solve this, we need to isolate g, we can divide both sides by -3.55

g ≤ -28.4/-3.55 = 8

g ≤ 8

Then we must have a black dot at x = 8, and we shade the region to the left of it, meaning that the correct graph is the last one.

Rosencrantz and Guildenstern Are Dead follows the "off-stage" exploits of two minor characters from Hamlet, Rosencrantz and Guildenstern. While the two main characters in Stoppard's play occasionally make brief appearances in "Hamlet," as scripted in Shakespeare's original tragedy, the majority of the play takes place in other parts of the castle where Hamlet is set. While "off stage" in this way, the characters resemble the main characters in the absurdist Waiting for Godot. As in Beckett's play, Rosencrantz and Guildenstern pass the time by impersonating other characters, engaging in word play, and remaining silent for long periods of time. These same two characters were also featured in a parody of Hamlet, the short comic play by W. S. Gilbert entitled Rosencrantz and Guildenstern.
