Jason wants to know the percentage of M & M's that are green. He chooses a sample of 30 M & M's from a bag, and 3 of them are green. What is the margin of error of his experiment (round to 4 decimal places)? .1074 .1074 .9845 .9845 .1235 .1235 .8824

Answers

Answer:

The margin of error of his experiment is of 0.1074.

Step-by-step explanation:

In a sample with a number n of people surveyed with a probability of a success of [tex]\pi[/tex], and a confidence level of [tex]1-\alpha[/tex], we have the following confidence interval of proportions.

[tex]\pi \pm z\sqrt{\frac{\pi(1-\pi)}{n}}[/tex]

In which

z is the z-score that has a p-value of [tex]1 - \frac{\alpha}{2}[/tex].

The margin of error is of:

[tex]M = z\sqrt{\frac{\pi(1-\pi)}{n}}[/tex]

30 M & M's from a bag, and 3 of them are green.

This means that [tex]n = 30, \pi = \frac{3}{30} = 0.1[/tex]

Standard 95% confidence level

So [tex]\alpha = 0.05[/tex], z is the value of Z that has a p-value of [tex]1 - \frac{0.05}{2} = 0.975[/tex], so [tex]Z = 1.96[/tex].

Margin of error:

[tex]M = z\sqrt{\frac{\pi(1-\pi)}{n}}[/tex]

[tex]M = 1.96\sqrt{\frac{0.1*0.9}{30}}[/tex]

[tex]M = 0.1074[/tex]

The margin of error of his experiment is of 0.1074.

Write the slop form of an equation of the line thet passes throughtl (4-3)and(2,1

Answers

Answer:

y+2x-5= 0

Step-by-step explanation:

Applying,

(y-y₁) = m(x-x₁)............... Equation 1

Where m = slope

But,

m = (y₂-y₁)/(x₂-x₁)

Given: y₁ = -3, y₂ = 1, x₁ = 4, x₂ = 2

m = (1+3)/(2-4)

m = 4/-2

m = -2

Substituting into equation 1

(y+3) = -2(x-4)

y+3 = -2x+8

y = -2x+8-3

y = -2x+5

y = 5-2x

y+2x-5 = 0

This is a right triangle. To find the third side of a right triangle. Use the Pythagorean Theorem.
a^2+b^2=c^2
a and b are the legs, c is the hypotenuse.
a^2+7^2=16^2
a^2+49=256
Subtract 49 from both sides:
a^2=207
Square foot:
a=14.38749457 in.
Round to nearest tenth:
14.4 in

Answer:

a = 14.4

Step-by-step explanation:

It's a right angled triangle. so it has to follow Pythagoras Theorem

according to it square of hypotenuse = sum of squares of other two sides

[tex]16 {}^{2} = {x}^{2} + 7 {}^{2} \\ 256 = x {}^{2} + 49 \\ 256 - 49 = x {}^{2} \\ 207 = x {}^{2} \\ x = \sqrt{207 } \\ x = 14.387 \\ x = 14.4[/tex]

The local amusement park was interested in the average wait time at their most popular roller coaster at the peak park time (2 p.m.). They selected 13 patrons and had them get in line between 2 and 3 p.m. Each was given a stopwatch to record the time they spent in line. The times recorded were as follows (in minutes): 118, 124, 108, 116, 99, 120, 148, 118, 119, 121, 45, 130, 118. What is the mode

Answers

Answer:

118

Step-by-step explanation:

Mode refers to a value that appears most frequently in a data set.

For example the mode in the data set below is 3 :

1, 2,3 4,3,3,9,10

3 is the mode because it appears 3 times while others appear once in the data set while the other values appear only once.

Mode is a measure of central tendency

118 appears 3 times while others appear once so it is the mode

What is the length of BC? Please include how you got it :)

Answers

Answer:

BC = 24

Step-by-step explanation:

We know that triangles CAB and CED are similar because all three of their angles are the same. Thus, we know that the side lengths of these triangles have to be proportional to each other. You would match side BC with side DC and sides AC with EC.

AC/EC = BC/DC

30/10 = (32-x)/x

3 = (32-x)/x

Then using algebraic properties, solve for x.

3x = 32 - x

4x = 32

x = 8.

Lastly, plug in 8 for the x in BC, 32 - 8, so the length of BC is 24

Answer:

B

Step-by-step explanation:

Δ CBA and Δ CDE are similar triangles, then the ratios of corresponding sides are equal, that is

[tex]\frac{CB}{CD}[/tex] = [tex]\frac{CA}{CE}[/tex] , substitute values

[tex]\frac{32-x}{x}[/tex] = [tex]\frac{30}{10}[/tex] = 3 ( multiply both sides by x )

32 - x = 3x ( add x to both sides )

32 = 4x ( divide both sides by 4 )

8 = x

Then

BC = 32 - x = 32 - 8 = 24 → B

Find all angles, 0≤θ<360, that satisfy the equation below, to the nearest 10th of a degree. 4tan^2 θ+tanθ=−4tanθ−1

Answers

Answer:

135 and 315degrees

Step-by-step explanation:

Given the expression

4tan²θ+tanθ=−4tanθ−1

Equate to zero

4tan²θ+tanθ+4tanθ+1 = 0

4tan²θ+5tanθ+1 = 0

Let x = tanθ

4x²+5x+1 = 0

Factorize;

4x²+4x+x+1 = 0

4x(x+1)+1(x+1) = 0

4x+1 = 0 and x+1 = 0

4x = -1 and x = -1

x = -1/4 and -1

Since x = tanθ

-1 =tanθ

θ = arctan(-1)

θ = -45degrees

Since tan is negative in the 2nd and fourth quadrant;

In the second quadrant

θ = 180 - 45 = 135degrees

In the fourth quadrant;

θ = 360 - 45 = 315degrees

Hence the required angles are 135 and 315degrees

Which of the following actions may Congress take to advance civil rights? Overview In this assignment, you will gain more practice with designing a program. Specifically, you will create pseudocode for a higher/lower game. This will give you practice designing a more complex program and allow you to see more of the benefits that designing before coding can offer. The higher/lower game will combine different programming constructs that you have been learning about, such as input and output, decision branching, and a loop. IT 140 Higher/Lower Game Sample Output Overview Maria has asked you to create a program that prompts the user to enter the lower bound and the upper hound. You have decided to write pseudocode to design the program before actually developing the code. When run, the program should ask the user to guess a number. If the number guessed is lower than the random number, the program should print out a message like "Nope, too low." if the number guessed is higher than the random number, print out a message like "Nope, too high." If the number guessed is the same as the random number, print out a message like "You got it!" Higher/Lower Game Description Your friend Maria has come to you and said that she has been playing the higher/lower game with her three-year-old daughter Bella. Maria tells Bella that she is thinking of a number between 1 and 10, and then Bella tries to guess the number. When Bella guesses a number, Maria tells her whether the number she is thinking of is higher or lower or if Bella guessed it. The game continues until Bella guesses the right number. As much as Maria likes playing the game with Bella, Bella is very excited to play the game all the time, Maria thought it would be great if you could create a program that allows Bella to play the game as much as she wants. Note: The output messages you include in your pseudocode may differ slightly from these samples. Sample Output Below is one sample output of the program, with the user input demonstrated by bold font. Prompt For this assignment, you will be designing pseudocode for a higher/lower game program. The higher/lower game program uses similar constructs to the game you will design and develop in Projects One and TWO. Welcome to the higher/lower game, Bella! Enter the lower bound: 10 Enter the upper bound: 30 Great, now guess a number between 10 and 30: 20 Nope, too low Guess another number: 25 Nope, too high Guess another number: 23 You got it! Below is another sample output of your program, with the user input demonstrated by bold font 1. Review the Higher/Lower Game Sample Output for more detailed examples of this game. As you read, consider the following questions: What are the different steps needed in this program? How can you break them down in a way that a computer can understand? What information would you need from the user at each point (inputs)? What information would you output to the user at each point? When might it be a good idea to use 'F' and "IF ELSE' statements? When might it be a good idea to use loop? 2. Create pseudocode that logically outlines each step of the game program so that it meets the following functionality: Prompts the user to input the lower bound and upper bound. Include input validation to ensure that the lower bound is less than the upper bound. - Generates a random number between the lower and upper bounds Prompts the user to input a guess between the lower and upper bounds. Include input validation to ensure that the user only enters values between the lower and upper bound. Prints an output statement based on the puessed number. Be sure to account for each of the following situations through the use of decision branching . What should the computer output if the user guesses a number that is too low? . What should the computer output if the user guesses a number that is too high? - What should the computer output if the user guesses the right number? Loops so that the game continues prompting the user for a new number until the user guesses the correct number. Welcome to the higher/lower game, Bella! Enter the lower bound: 10 Enter the upper bound: 5 The lower bound must be less than the upper bound. Enter the lower bound: 10 Enter the upper bound: 20 Great, now guess a number between 10 and 20: 25 Nope, too high Guess another number: 15 Nope, too low. Guess another number: 17 You got it!
