The probability that x=9 for a Poisson distribution with μ=9 is 0.126.

The probability that x=9 for a Poisson distribution with μ=9 can be found using the formula P(x) = (e^-μ * μ^x) / x!.

Let's first understand what is Poisson ratio:

In mathematics, Poisson's ratio is a measure of the deformation of a material in response to an applied force. Specifically, it is the ratio of the relative contraction or compression of the material perpendicular to the direction of the applied force, to the relative extension or stretching of the material in the direction of the applied force.

Step 1: Plug in the values for x and μ into the formula.
P(9) = (e^-9 * 9^9) / 9!

Step 2: Simplify the equation.
P(9) = (0.00012341 * 387420489) / 362880

Step 3: Calculate the final probability.
P(9) = 0.126

The new price of the van is $10,640.

Percentage is a measure of frequency that is used to determine the value of a number as a number out of 100. The sign that is used to represent percentage is %. Percentage is a measure of frequency.

The price of the van would decline by the suggested percentage decrease.

New price of the van = initial price - value of the 5%

Value of the 5% = 5% x 11,200 = $560

Price of the van = 11,200 - $560 = $10,640

Alternatively, New price of the van = old price x (1 - percent decrease)

$11,200 x ( 100 - 5%)

$11,200 x 95%

$11,200 x 0.95

To find the probability that first E and then F results, we need to multiply the probability of E by the probability of F given that E has occurred. The probability of E is 1/5.

Since E and F are independent, the probability of F given that E has occurred is simply the probability of F, which is 2/3.

So, the probability of first E and then F results is:

P(E and F) = P(E) * P(F|E) = (1/5) * (2/3) = 2/15

Therefore, the probability that in a compound experiment, first E and then F results is 2/15.

Given that event E has probability 1/5 and event F has probability 2/3, and both events are independent, we can find the probability of E happening first and then F happening in a compound experiment by multiplying the probabilities of the individual events.

Step 1: Identify the probability of event E: P(E) = 1/5
Step 2: Identify the probability of event F: P(F) = 2/3
Step 3: Since events E and F are independent, we multiply their probabilities to find the probability of both events happening sequentially: P(E and F) = P(E) * P(F)

So, P(E and F) = (1/5) * (2/3) = 2/15

The probability of event E happening first and then event F happening in a compound experiment is 2/15.

Step-by-step explanation:

I just used a pyramid calculator online and inputed the base and height.

The distance from the top of the pyramid, to each vertex of the base would be 10.5 unit.

If ABC is a triangle with AC as the hypotenuse and angle B with 90 degrees then we have:

\(|AC|^2 = |AB|^2 + |BC|^2\)

where |AB| = length of line segment AB. (AB and BC are rest of the two sides of that triangle ABC, AC being the hypotenuse).

A right square pyramid has an altitude of 10 and each side of the base is 6. we need to find the slant height of the pyramid.

From the Pythagoras' theorem

\(|AC|^2 = |AB|^2 + |BC|^2\)

\(s^2 = h^2 + (b/2)^2\\\\s^2 = 10^2 + (6/2)^2\\\\s^2 = 100 + 9\\\\s^2 = 109\\\\s = \sqrt109\\\\s = 10.5\)

Thus, the distance from the top of the pyramid, to each vertex of the base would be 10.5 unit.

Explanation:

The first term is 4 because of the notation \(a_1 = 4\)

To get the second term, we'll use the recursive equation \(a_n = 5(a_{n-1})-1\) which basically says \(\text{nth term} = 5*(\text{previous term})-1\). To get the second term, we'll multiply the first term by 5, then subtract off 1.

2nd term = 5*(1st term) - 1

2nd term = 5*4 - 1

2nd term = 19

This means \(a_2 = 19\)

We repeat this process again to find the third term \(a_3\)

\(a_n = 5*(a_{n-1})-1\\\\a_3 = 5*(a_{3-1})-1\\\\a_3 = 5*(a_{2})-1\\\\a_3 = 5*(19)-1\\\\a_3 = 95-1\\\\a_3 = \boldsymbol{94}\\\\\)

The type of model selection method that the scientist should use is a stepwise regression.

In statistics, stepwise regression is a method of fitting regression models in which the selection of predictive variables is done automatically. Each step considers a variable for addition to or subtraction from the set of explanatory variables based on some predetermined criterion.

To determine which predictors are significant in the model to predict movie success, we should use the step-wise regression method which is a model selection method.

Stepwise regression is a method for testing the statistical significance of each independent variable in a linear regression model iteratively. The forward selection method begins with nothing and gradually adds each new variable, testing for statistical significance along the way.

The underlying goal of stepwise regression is to identify a set of independent variables that significantly influence the dependent variable through a series of tests (e.g., F-tests, t-tests). Stepwise regression has the following advantages: The ability to manage a large number of potential predictor variables while fine-tuning the model to select the best predictor variables from among the available options. It is faster than other methods of automatic model selection.

We have a sample of x=weights with the following data:

• Min = 107

• Q1(x) = 197

• Median(x) = 264

• Q3(x) = 312

• Max(x) = 426

1) The percent of the chicks weight more than 197, this is the value of the Q1. The quartile 1 represent the value of x that the 25% of the sample has a value less o equal to that.

So the percent of chicks that have a weight greater than 197 is 75%.

2) For the weight more than 264, correspond to the Median, so the 50% of sample has a weight lower or equal 264, and the other 50% has a weight greater or equal to 264.

So, the percent is 50%.

3) The weight of 312 correspond with Q3, so the 75% of the sample has a weight less or equal to 312, and the other 35% has a weight greater than 312.

So, the percent is 25%.

4) The weigth are the percentil Q1 and Q3, respectively. So the percent of chicks that have a weigth between 197 and 312 is 75%-25% = 50%

The mass of the water can be determined using the formula for heat transfer, which states that heat transferred (in calories) is equal to the mass of the substance (in grams) multiplied by the specific heat capacity of the substance (in calories/gram°C) multiplied by the change in temperature (in °C). By rearranging the formula, we can find that the mass of water is equal to the heat transferred divided by the product of the specific heat capacity and the temperature change.

Given:

Initial temperature (T1) = 45°C

Final temperature (T2) = 25°C

Heat transferred (Q) = 20 calories

Specific heat capacity of water (C) = 1 calorie/gram°C

We can use the formula for heat transfer:

Q = m * C * ΔT

Where:

Q is the heat transferred,

m is the mass of the substance,

C is the specific heat capacity of the substance, and

ΔT is the change in temperature.

Rearranging the formula, we have:

m = Q / (C * ΔT)

Substituting the given values:

m = 20 calories / (1 calorie/gram°C * (45°C - 25°C))

Simplifying the equation:

m = 20 calories / (1 calorie/gram°C * 20°C)

m = 20 grams

Therefore, the mass of water is 20 grams.

The probability of not getting a diamond card is \(\frac{3}{4}\) .

What is probability ?

 The area of mathematics known as probability deals with numerical descriptions of how likely it is for an event to happen or for a claim to be true. A number between 0 and 1 is the probability of an event, where, broadly speaking, 0 denotes the event's impossibility and 1 denotes its certainty.

The total number of outcomes of a deck of 52 cards are 52.

Since, there are 13 cards of diamond in a deck of 52 cards, therefore, the total number of favourable outcome that it is not a diamond is ,

=> 52-13= 39.

Therefore, probability P of not getting a diamond card is:

P= \(\frac{39}{52}\) = \(\frac{3}{4}\)
