P(X = 7), λ = 6: The Poisson probability of X = 7, with a parameter (λ) value of 6, is 0.1446. P(X = 11), λ = 12: The Poisson probability of X = 11, with a parameter (λ) value of 12, is 0.0946. P(X = 6), λ = 8: The Poisson probability of X = 6, with a parameter (λ) value of 8, is 0.1206.

The Poisson probability is used to calculate the probability of a certain number of events occurring in a fixed interval of time or space, given the average rate of occurrence (parameter λ). The formula for Poisson probability is P(X = k) = (e^-λ * λ^k) / k!, where X is the random variable representing the number of events and k is the desired number of events.

To calculate the Poisson probabilities in this case, we substitute the given values of λ and k into the formula. For example, for the first case (a), we have λ = 6 and k = 7: P(X = 7) = (e^-6 * 6^7) / 7!

Using a calculator, we can evaluate this expression to find that the probability is approximately 0.1446. Similarly, for case (b) with λ = 12 and k = 11, and for case (c) with λ = 8 and k = 6, we can apply the same formula to find the respective Poisson probabilities.

The null and alternative hypothesis for testing to see if there is a relatonsip between age and opinion for the question asked by gallup is Divorce Opinions and Gender I.

We introduce the results of a

May 2010 Gallup poll of 1029 US adults. When asked if they view divorce as “morally acceptable”,

71% of the men and 67% of the women in the sample responded yes. In the test for a difference in

proportions, a randomization distribution gives a p-value of 0.165. Does this indicate a significant

Solution

If we use a 5% significance level, the p-value of 0.165 is not less than α = 0.05 so we would not

reject H0 : pf = pm. This means the data do not show significant evidence of a difference in the

proportions of men and women that view divorce as “morally acceptable”

Solution

(a) The p-value (0.003) is small so the decision is to reject H0 and conclude that the mean recall

for sleep (¯xs = 15.25) is different from the mean recall for caffeine (¯xc = 12.25). Since the mean

Answer:

Scale factor = \(\frac{1}{2}\)

Step-by-step explanation:

Perimeter of the actual flag = 22 in.

Perimeter of the scale drawing of the flag = 11 in.

Since, perimeter of a triangle = Sum of all three sides of the given triangle

Therefore, scale factor of the drawing

= \(\frac{\text{Measure of the side of drawing}}{\text{Measure of the side of actual}}\) = \(\frac{\text{Perimeter of drawing}}{\text{Perimeter of actual}}\)

= \(\frac{11}{22}\)

= \(\frac{1}{2}\)

Therefore, scale factor of the drawing will be \(\frac{1}{2}\).                                        

Each side of the scaled triangle will be half of the actual triangle.

Answer:

Let <DEF= x°

<CDE= 2x°

<BAF= 90°

The sum of interior angle of hexagon= 720°

\(90 + 145 + 115 + 2x + x + 160 = 720 \\ 510 + 3x = 720 \\3x + 510 = 720 \\ 3x + 510 - 510 = 720 - 510 \\ 3x = 210 \\ \frac{3x}{x} = \frac{210}{3} \\ x = 70 \: degree\)

m > 8 is an inequality used to calculate the number of articles Mustafa could have written.

Let's assume that Mustafa has written m articles for the school newspaper.

Then, according to the given information:

Heloise has written 1/4 as many articles as Mustafa has, which means she has written 1/4 × m = m/4 articles.

Gia has written 3/2 as many articles as Mustafa has, which means she has written 3/2 × m = 3m/2 articles.

The combined total of articles written by all three is more than 22, so we can write:

m/4 + 3m/2 + m > 22

Simplifying and solving for m:

11m/4 > 22

m > 22 × 4/11

m > 8

Therefore, m > 8 is an inequality used to calculate the number of articles Mustafa could have written.

the jensen measure of performance evaluation for sooner stock fund will be 2.6%.

What is the percentage?

A percentage that represents a tenth of a quantity. One percent, denoted by the symbol 1%, is equal to one-hundredth of something; hence, 100 percent denotes the full thing, and 200 percent designates twice the amount specified. A portion per hundred is what the percentage denotes. The percentage refers to one in a hundred. The % sign is used to denote it.

the risk-free return during the sample period was 3%.

performance evaluation for sooner stock fund.

Expected return of Sooner Stock Fund = E(Rp) = 20%

Beta of stock = 1.8

risk free rate Rf = 3%

Market Return Rm = 11%

So, Jensen measure alpha = E(Rp) - Rf - beta*(Rm - Rf) = 20 - 3 - 1.8*(11-8) = 2.6%

Hence the Jensen measure of performance evaluation for the sooner stock fund will be 2.6%.

Function f(x) = ax\(e^{(bx^{2} )}\)to be well-defined, there are no specific restrictions on a and b, both a and b have any real numbers.

Function is equal to,

f(x) = ax\(e^{(bx^{2} )}\)

To determine the values of a and b for which the function f(x) = ax\(e^{(bx^{2} )}\) is well-defined,

Consider the conditions that ensure the function remains finite and defined for all values of x.

For the function f(x) = ax\(e^{(bx^{2} )}\) to be well-defined,

The exponential term \(e^{(bx^{2} )}\) must be defined for all real values of x.

The product ax must also be defined for all real values of x.

Let us examine these conditions,

Exponential term,

The exponential function \(e^{(bx^{2} )}\) is always defined for any real value of x.

There are no restrictions on the values of b that would make the exponential term undefined.

Product term,

The product ax must be defined for all real values of x.

This means that both a and x must be real numbers, and their product must be finite.

There are no restrictions on the values of a that would make the product term undefined.

Therefore, for function f(x) = ax\(e^{(bx^{2} )}\)  is well defined there are no specific restrictions on values of a and b, both a and b can be any real numbers.

The height of lighthouse is 72.54

Given,

In the question:

To see the figure:

To find the height of lighthouse.

Now, According to the question:

In Triangle ABD

tan 20° = \(\frac{h}{20 + x}\)

0.36  = \(\frac{h}{20 + x}\)

=> (20 + x)0.36 = h

=> 0.72 + 0.36x = h

=> x = \(\frac{h - 72}{0.36}\) .....(1)

In Triangle ABC

tan 34° = h/x

=> 0.67 = \(\frac{h}{\frac{h-72}{0.36} }\)

=> 0.67 = 0.36/h - 72

=> 0.67 (h - 72) = 0.36

=> h - 72 = 0.54

=> h = 0.54 + 72

=> h = 72.54

Hence, The height of lighthouse is 72.54
