This can be modeled as a Poisson distribution. The mean number of patients admitted per day is 2.5, so the Poisson parameter λ = 2.5. The probability that the hospital will not have enough beds on any given day is the probability that more than 1 patients will be admitted, which is given by:

P(X > 1) = 1 - P(X <= 1)

= 1 - (P(X = 0) + P(X = 1))

= 1 - (e^-2.5 * 0 + e^-2.5 / 1!)

= 1 - e^-2.5 * (1 + 2.5)

This is the probability that the hospital will not have enough beds to accommodate its newly admitted patients on any given day.

AnswerStep-by-step explanation:

.99 is right, you already know.

So first,

8 Down arrow 2

means sqrt8

The 8 goes inside the sqrt and the 2 goes outside (its called an index) but we like never write that 2. Its just a normal square root. If you are using a calculator (I think practically, you must use a calculator) you can find sqrt8. Then

take

sqrt8 UpArrow 6

means (sqrt8)^6

this is 8^3 or on the calculator 512.

Next,

512 SideArrow 500

means 500/512

this is .9765625

Lastly,

.9765625 DownArrow 4

means

4throot(.9765625)

Your calculator might have a 4throot button, but you can use 1/4 power instead because all roots can be written like fraction powers.

When .9765625 is in your calculator screen you can just use the ^ button or x^y button to raise it to the 1/4 power. (Use .25 for 1/4 or use parenthesis on the (1/4) )

(.9765625)^.25

Answer: Observational

Step-by-step explanation:

If it is a experiment then you can conclude that a variable caused a response

In statistics, correlation refers to the degree to which two variables are related or associated with each other. When the correlation between two variables is close to 1.0, it indicates a strong positive relationship between them. However, it is important to note that this strong correlation does not necessarily imply a cause-and-effect relationship between the two variables, especially in a study where certain conditions may not be met.

A study is a systematic investigation aimed at acquiring knowledge and understanding of a particular phenomenon or subject matter. In order to establish a causal relationship between two variables, certain conditions need to be met, such as the establishment of a temporal sequence, a clear association between the variables, and the elimination of any confounding variables that may influence the outcome. These conditions are essential for any study seeking to establish a cause-and-effect relationship between variables.

In the absence of these conditions, even if the correlation between two variables is close to 1.0, it cannot be concluded that the explanatory variable causes changes in the response variable. This is because correlation does not imply causation. Correlation simply indicates the strength of the association between two variables, but it does not provide information about the direction or the underlying mechanisms of the relationship.

For instance, consider a study examining the relationship between smoking and lung cancer. The study finds a strong positive correlation between smoking and lung cancer, indicating that smokers are more likely to develop lung cancer than non-smokers. However, this correlation alone does not necessarily prove that smoking causes lung cancer. There may be other factors such as air pollution, family history, or genetics that could influence the development of lung cancer.

In summary, the correlation between two variables is a measure of the strength of the association between them. A high correlation does not necessarily imply a cause-and-effect relationship between the variables, especially in a study where certain conditions may not be met. It is important to consider these conditions and rule out other factors that could influence the outcome before drawing any conclusions about the causal relationship between two variables.

The value of a is given as follows:

a = 12.

We have two parallel lines that are cut by a transversal, and the two angles are between the parallel lines and on the same side of the transversal, meaning that they are consecutive interior angles.

Consecutive interior angles are supplementary, meaning that the sum of their measures is of 180º, hence the value of a can be found as follows:

The solution to the system of equations in this problem is given as follows:

The system of equations for this problem is defined as follows:

From the first equation, we have that:

ab^6 = 42

a = 42/(b^6)

a = 42b^(-6).

Replacing on the second equation, we have that the value of b is obtained as follows:

15 = 42b^(-6) x b^9

15 = 42b³

b = (15/42)^(1/3)

b = 0.71.

Here we have to determine the total surface area (TSA)of the wheel of cheese.

Since the cheese is a cylinder shaped thing.

The formula for the total surface area (TSA) of the wheel:

TSA = 2πr (r + h)

Substituting the values of the variables into the formula, we have

Answer:

a ) $11.5

b.) 10 million gallons

Step-by-step explanation:

a.) Since it's asking for p if x = 20, we can plug 20 into the original equation

[tex]0.2(20) + 4p = 50[/tex]

0.2 times 20 is 4

4 + 4p = 50. Next we would subtract 4 from each side giving us

4p = 46. Lastly, divide each side by 4

p = 11.5

b.) If the p, also known as p increases by 50 cents, that means it goes from 11.5 to 12.

Now we plug in 12 to p and look for x, the opposite

[tex]0.2x + 4(12) = 50[/tex]

4 times 12 is 48, making it

0.2x + 48 = 50. This is where we subtract 48

0.2x = 2. and lastly, divide by 0.2, making...

x = 10

So demand decreased by 10 million because 20-10=10

The interval of continuity of the function is continuous given y = 2 (x + 4 ) 2 + 8 is (-∞, ∞).

A function is continuous at a point if the function value exists and is finite at that point, and the limit of the function as the input approaches that point from the left and right side is equal to the function value at that point. In other words, the function has no sudden jumps or discontinuities at that point.

In the case of the function y = 2(x + 4)² + 8, the function is defined and continuous for all real numbers x. There are no values of x for which the function is undefined or has a discontinuity, so the function is continuous for all values of x, meaning that the interval of continuity is (-∞, ∞).

An area is total space occupied by two-dimensional or flat surfaces. In other words we can say that it is a number of unit squares present in a closed figure. We use various units for measurement of area like, cm², m², ft², mm².

Perimeter is a mathematical term, which means total outer boundary of a figure, we define it only for two dimensional figures.

Perimeter = Sum of length of the all the sides

The room is into rectangle shape,

Base area of room = length x width

                               =  11 x 11

Perimeter of base of the room = Sum of lengths and widths
