You are a travel agent and wish to estimate, with a 95% confidence, the proportion of vacationers who plan to travel outside the United States in the next 12 months. Your estimate must be accurate within 3% of the true proportion. a) no preliminary estimate is available. Find the minimum sample size needed. b) find the minimum sample size needed, using a prior study that found that 26% of the respondents said they planned to travel outside the United States in the next 12 months.

Answers

The minimum sample size needed is 193.

What do you mean by preliminary estimate?

A preliminary estimate, also known as a preliminary budget or a rough estimate, is an early approximation of the cost or resources required for a project, program, or activity. It is made before a more detailed and accurate assessment is completed and is used to help make initial decisions and allocate resources.

A preliminary estimate is typically made based on available information and expert judgment, and it can be subject to revision as more information becomes available. It is an important tool for project planning, as it helps to establish a baseline for the cost or resource requirements of a project and provides a basis for making decisions about the feasibility and scope of the project.

A preliminary estimate can also be used to secure funding, establish project schedules, and identify potential risks and challenges. It is important to note that a preliminary estimate is not a final or binding commitment, and that the actual cost or resource requirements of a project may differ from the preliminary estimate.

a) No preliminary estimate is available:

The formula for minimum sample size for estimating a proportion with a margin of error and a given level of confidence is:

n = (Z² × p × (1 - p)) / E²

Where:

Z = the Z-score that corresponds to the desired level of confidence (95% confidence corresponds to a Z-score of 1.96)

p = estimated proportion (since no preliminary estimate is available, a commonly used value is 0.5)

E = desired margin of error (3%)

Plugging in the values, we get:

n = (1.96² × 0.5 × (1 - 0.5)) / (0.03²) = 384

So, the minimum sample size needed is 384.

b) Using a prior study that found 26% of the respondents said they planned to travel outside the US:

Plugging in the prior estimate of p = 0.26 and the same Z and E values as above, we get:

n = (1.96² × 0.26 × (1 - 0.26)) / (0.03²) = 193

So, the minimum sample size needed is 193.

Mantago wants to borrow $10,000 to buy a used car. He examined his budget and decides that he can affors a payment of $200 a month. If his bank offers him an APR of 7. 5%, how long should he borrow the money so he can afford his monthly payment?

Answers

Mantago should borrow the money for 72.7 months or approximately 6 years,

We can use the following formula to determine the loan length:

Loan length = Loan amount / (Monthly payment - Monthly interest payment)

We must first determine the monthly interest payment, which may be done by applying the following formula:

Monthly interest payment = (APR / 12) * Loan amount

Plugging in the values:

Monthly interest payment = (7.5 / 12) * $10,000 = $62.5

The values can now be entered into the calculation to determine the length of the loan:

Loan length = $10,000 / ($200 - $62.5) = $10,000 / $137.5 = 72.7 months

Therefore, Mantago should borrow the money for 72.7 months, or approximately 6 years, in order to afford the monthly payment of $200.

(2 points) conditional probability. a fair coin is tossed twice. (a) (1 point) what is the probability of two heads if we know that the first toss is a head? (b) (1 point) what is the probability of two heads if we know that at least one toss is a head?

Answers

If we know that the first toss is a head, the probability of two heads is 1/2. The probability of two heads if we know that at least one toss is a head is 2/3.

(a) If we know that the first toss is a head, the probability of two heads is 1/2 because the second toss is still independent and has a 50% chance of being either heads or tails.

(b) If we know that at least one toss is a head, the probability of two heads can be found by adding up the probability of getting two heads on the first and second tosses and then getting heads on the first and tails on the second toss. This can be represented as:

P(two heads | at least one head) = P(two heads) / P(at least one head) = (P(heads on first and heads on second) + P(heads on first and tails on second)) / (1 - P(tails on first and tails on second))

Since each toss has a 50% chance of being heads, the probability of getting two heads on the first and second tosses is 0.5 × 0.5 = 0.25. The probability of getting heads on the first and tails on the second is also 0.5 × 0.5 = 0.25. And the probability of getting tails on both tosses is 0.5 × 0.5 = 0.25.

Therefore, the answer is:

P(two heads | at least one head) = (0.25 + 0.25) / (1 - 0.25) = 0.5 / 0.75 = 2/3

So the probability of two heads, if we know that at least one toss is a head, is 2/3.

Ratio, Proportion ar d) 15 workers were employed to complete a piece of work in 36 d .how many more workers should be added to comelete the work in 30 days​

Answers

The required number of workers need to  to add 4 more workers to complete the work in 30 days.

How we find the number of workers?

To determine how many more workers are needed to complete the work in 30 days, we first need to calculate the daily work rate for 15 workers.

If 15 workers can complete the work in 36 days, then their daily work rate is =15 workers * 1 day/36 days

= 15/36 workers per day.

Next, we need to determine how much work needs to be done in 30 days.

This can be calculated by multiplying the daily work rate by the number of days:

15/36 workers per day * 30 days

= 10.5 workers.

Since we can't have fractional workers, we round up to 11 workers.

So, we need

11 - 15 = -4 more workers to complete the work in 30 days.

Since we cannot have negative workers, we actually need to add 4 more workers to complete the work in 30 days.

solve the following systems of linear equations using substitution

4x - 2y = 20 and x - 4y = -16

Answers

Answer:

The solution to this system of linear equations is (x, y) = (8, 6)

Step-by-step explanation:

We can solve this system of linear equations using substitution. To start, we'll isolate one of the variables in one of the equations, then substitute that expression into the other equation.

Starting with the first equation, we'll isolate x:

4x - 2y = 20

4x = 20 + 2y

x = 5 + 0.5y

Next, we'll substitute this expression for x into the second equation:

x - 4y = -16

5 + 0.5y - 4y = -16

5 - 3.5y = -16

Adding 3.5y to both sides:

5 = 3.5y - 16

Adding 16 to both sides:

21 = 3.5y

Finally, dividing both sides by 3.5:

y = 6

So, the value of y is 6. To find x, we can substitute this value back into the expression we found earlier:

x = 5 + 0.5y

x = 5 + 0.5(6)

x = 5 + 3

x = 8

So, the solution to this system of linear equations is (x, y) = (8, 6).

Answer:

(8, 6)

Step-by-step explanation:

Given system of linear equations:

[tex]\begin{cases}4x - 2y = 20 \\x - 4y = -16\end{cases}[/tex]

Rearrange the second equation to isolate x:

[tex]\implies x=4y-16[/tex]

Substitute the found expression for x into the first equation and solve for y:

[tex]\implies 4(4y-16)-2y=20[/tex]

[tex]\implies 16y-64-2y=20[/tex]

[tex]\implies 14y-64=20[/tex]

[tex]\implies 14y=84[/tex]

[tex]\implies y=6[/tex]

Substitute the found value of y into the expression for x and solve for x:

[tex]\implies x=4(6)-16[/tex]

[tex]\implies x=24-16[/tex]

[tex]\implies x=8[/tex]

Therefore, the solution to the given system of linear equations is (8, 6).

y = a/b (x+c) (x-1)

Answers

The precise quadratic equation, according to the provided assertion, is y = (1/9)x² + (2/9)x - 1/3.

How is the quadratic function discovered?

Three elements decide a quadratic function of the formula f(x) = ax² + bx + c. A quadratic function can be determined by getting a, b, and c algebraically given three locations on the graph. In order to do this, a system of eqs with three unknowns must be solved.

To find the quadratic function that passes through the point (-8, 5) and has zeros at x = -3 and x = 1, we can start by using the factored form of a quadratic function:

y = a(x - r)(x - s)

where r and s are the zeros of the function. Substituting in the given zeros, we get:

y = a(x + 3)(x - 1)

To find the value of a, we can use the fact that the function passes through the point (-8, 5). Substituting these values into the equation, we get:

5 = a(-8 + 3)(-8 - 1)

Simplifying this expression, we get:

5 = a(-5)(-9)

5 = 45a

a = 1/9

Substituting this value of a into the equation we get:

y = (1/9)(x + 3)(x - 1)

Expanding the equation, we get:

y = (1/9)(x² + 2x - 3)

Multiplying both sides by 9 to eliminate the fraction, we get:

9y = x² + 2x - 3

So the quadratic function that passes through the point (-8, 5) and has zeros at x = -3 and x = 1 is:

9y = x² + 2x - 3

or

y = (1/9)x² + (2/9)x - 1/3.

By the Pythagorean theorem in a right angle triangle, the sum of the squares of sides will equal the square of the hypotenuse.

The altitude drawn on a hypotenuse will divide the triangle into two similar triangles

Here we have

Two right-angle triangle  

As we know in right angle triangle,

=> Hypotenuse² = Side² + Side²  

From the smaller right-angle triangle,

=> y² = (32)² + (24)²  

=> y² = 1024 + 576  

=> y² = 1600

=> y = 40    

Here the altitude drawn on the hypotenuse of the triangle divides the triangle into two similar triangles

Hence, the ratio of the corresponding angles in two triangles will be equal  

=> 32/x =  32/24  

=> 24(32) = 32(x)

=> x = 24

In 2nd largest triangle,  

=> z² = (32)² + (24)²

The ratio of length and width of floor of classroom will be same as the ratio of scale drawing. Therefore, representing the formula for ratio -

length/width (floor) = length/width (scale drawing)

32/28 = 16/width

Converting the original measurement to inches

1 foot = 12 inches

Length = 384 inches

Width = 336 inches

Rearranging the equation according to width of scale drawing

Width = (16 × 336)/384

Performing multiplication and division on Right Hand Side of the equation

Width = 14 inches

Thus, the width is 14 inches

Now, perimeter = 2(length + width)

Perimeter = 2 (16 + 14)

Perimeter = 2 × 30

Perimeter = 60 inches

Here's a dot plot for the number of losses for each season for the Minnesota Igloos:

 9  |  *

 10 |  *  *

 11 |  *  *  *

 12 |  *  *

Each dot represents a season, and the vertical axis represents the number of losses. The seasons with the same number of losses are stacked on top of each other.

Minnesota Igloos Loss Plot

To create the dot plot, I followed these steps:

I listed the unique values of the number of losses on the vertical axis, from the smallest value to the largest value.

For each value on the vertical axis, I placed a dot for each season with that number of losses.

I stacked the dots on top of each other for each value on the vertical axis that had more than one season with that number of losses.

By following these steps, I was able to visually represent the distribution of the number of losses for each season for the Minnesota Igloos in the form of a dot plot.

The cost of the camera in the first store is cheaper as the downpayment is the same for both stores but the monthly payment is cheaper in the first store.

What is a linear equation?

An equation of degree one is known as a linear equation.

A linear equation of two variables can be represented by ax + by = c.

The total cost for the first store is,

y = 10(12) + 60.

y = 120 + 60.

y = $160.

The total cost for the second store is,

y = 20(12) + 60.

y = 240 + 60.

y = $300.
