An apartment complex rents an average of 2.3 new units per week. If the number of apartments rented each week has a Polsson distribution, then the probability of renting exactly three apartments in a week is ....

Answers

The probability of renting exactly three apartments in a week is approximately 0.2018 or 20.18%.

If the average number of units rented per week is 2.3 and the distribution is Poisson, then the parameter lambda is also equal to 2.3.

The probability of renting exactly three apartments in a week is given by the Poisson probability function:

\(P(X = 3) = (e^(-lambda) * lambda^x) / x!\)

Substituting the values, we get:

\(P(X = 3) = (e^(-2.3) * 2.3^3) / 3!\)

P(X = 3) = (0.09963 * 12.167) / 6

P(X = 3) = 0.2018

Therefore, the probability of renting exactly three apartments in a week is approximately 0.2018 or 20.18%.

The following table gives information on GPAs and starting salaries (rounded to the nearest thousand dollars) of seven recent col- lege graduates.

Starting salary 48 53 50 37 65 32 37
Construct a 98% confidence interval for the mean starting salary of recent college graduates with a GPA of 3.15. Construct a 98% predic- tion interval for the starting salary of a randomly selected recent college graduate with a GPA of 3.15.

Answers

We can be 98% confident that the true mean starting salary of recent college graduates with a GPA of 3.15 lies between $36,540 and $55,740.

We can be 98% confident that the starting salary of a randomly selected recent college graduate with a GPA of 3.15 lies between -$32,080 and $124,360.

First, we need to calculate the sample mean, which is the average starting salary of the seven college graduates given:

sample mean = (48 + 53 + 50 + 37 + 65 + 32 + 37) / 7 = 46.14 thousand dollars

Next, we need to calculate the standard error. The sample standard deviation is calculated as follows:

s = √[((48-46.14)² + (53-46.14)² + (50-46.14)² + (37-46.14)² + (65-46.14)² + (32-46.14)² + (37-46.14)²) / 6] = 11.36 thousand dollars

The square root of the sample size is calculated as:

√(7) = 2.65

So, the standard error is:

standard error = 11.36 / 2.65 = 4.28 thousand dollars

Finally, we need to find the t-value for a 98% confidence level and 6 degrees of freedom (sample size - 1). We can use a t-table or a calculator to find this value, which is approximately 2.447.

Now we can plug in all the values into the formula to get the confidence interval:

Confidence interval = 46.14 ± 2.447 * 4.28 = (36.54, 55.74)

The t-value and standard error are calculated in the same way as in the confidence interval, but we also need to calculate the sample standard deviation, which is the square root of the variance:

variance = [(48-46.14)² + (53-46.14)² + (50-46.14)² + (37-46.14)² + (65-46.14)² + (32-46.14)² + (37-46.14)²] / 6

= 1315.43 thousand dollars squared

sample standard deviation = √(variance) = 36.26 thousand dollars

Now we can plug in all the values into the formula to get the prediction interval:

Prediction interval = 46.14 ± 2.447 * 4.28 ± 2.447 * 36.26 = (-32.08, 124.36)

if a certain star emits radiation that has a peak wavelength of 670 nm, the temperature of the star is

Answers

The temperature of the star emitting radiation with a peak wavelength of 670 nm is approximately 4325.37 K.

To get the temperature of a star with a peak wavelength of 670 nm, you can use Wien's Law, which states: T = b / λ_max where T is the temperature of the star, b is Wien's constant (approximately 2.898 x 10^6 nm K), and λ_max is the peak wavelength.
In this case, the peak wavelength (λ_max) is 670 nm. To calculate the temperature (T) of the star, follow these steps:
Step:1. Plug in the values into Wien's Law equation: T = (2.898 x 10^6 nm K) / (670 nm)
Step:2. Divide the constant by the peak wavelength: T ≈ (2.898 x 10^6) / 670
Step:3. Perform the calculation: T ≈ 4325.37 K
So, the temperature of the star emitting radiation with a peak wavelength of 670 nm is approximately 4325.37 K.

We calculate the value of number by multiplying the place value and face value of the digit.

The value formula is:

Value = Place Value × Face Value

Place value is the value of the column in which the number is. Each column in a number holds a different place value.

For exa.,  consider a number 456. Here, the place value of the digit 5 is tens and the place value of 4 is hundreds.

Tobin and Espi are pulling their own duct-tape boats along the edge of the pond. Tobin pulls at 25∘, and does 1900 J of work, while Espi pulls at 45∘, and does 1100 J of work. Which one pulls with the most force?

Answers

The ratio of the forces is less than 1, we can conclude that Tobin exerts a greater force than Espi. Therefore, Tobin pulls with the most force between the two individuals.

To determine which individual pulls with the most force, we need to compare the magnitudes of the forces exerted by Tobin and Espi. The work done by each person is related to the magnitude of the force applied and the displacement of the boat.

The work done by a force can be calculated using the formula:

Work = Force * Displacement * cos(θ)

Where:

Work is the work done (given as 1900 J for Tobin and 1100 J for Espi)

Force is the magnitude of the force applied

Displacement is the distance the boat is pulled

θ is the angle between the force and the direction of displacement

Let's denote the force exerted by Tobin as F_Tobin and the force exerted by Espi as F_Espi. We can set up the following equations based on the given information:

1900 = F_Tobin * Displacement * cos(25°)   (Equation 1)

1100 = F_Espi * Displacement * cos(45°)    (Equation 2)

To compare the forces, we can divide Equation 2 by Equation 1:

1100 / 1900 = (F_Espi * Displacement * cos(45°)) / (F_Tobin * Displacement * cos(25°))

Simplifying the equation:

0.5789 = (F_Espi * cos(45°)) / (F_Tobin * cos(25°))

The displacements cancel out, and we can evaluate the cosine values:

0.5789 = (F_Espi * (√2/2)) / (F_Tobin * (√3/2))

Simplifying further:

0.5789 = (F_Espi * √2) / (F_Tobin * √3)

To find the ratio of the forces, we can rearrange the equation:

(F_Espi / F_Tobin) = (0.5789 * √3) / √2

Evaluating the right side of the equation gives approximately 0.8899.

Since the ratio of the forces is less than 1, we can conclude that Tobin exerts a greater force than Espi. Therefore, Tobin pulls with the most force between the two individuals.

The relative frequency for the 55 - 60 class is equal to 0.022.

What is a class width?

In a frequency distribution table, a class width simply refers to the difference between the maximum) and minimum boundaries of any class in a data set.

This ultimately implies that, all classes must all have the same width in a frequency distribution table.

First of all, we would determine the total frequency as follows:

Total frequency = 8 + 10 + 6 + 7 + 15

Total frequency = 46.

Mathematically, the relative frequency of a class width can be calculated by using this formula:

Relative frequency = class frequency/total frequency

Answers

Answer:

44

Step-by-step explanation:

First, let's sum up the ratio.

Sum the ratios = 6 + 2 + 3 = 11

We can make y the total number of boots sold together last month

If 24 pairs of boots were sold, then the equation would be

6/11 × y = 24

Cross multiply

6 × y = 24 × 11

6y = 264

y = 44

Therefore, total number of boots sold altogether last month were 44
