The expected value or the average number of times a customer visits the store, given the probability distribution of X, is 1.4.

To find the expected value of X, we need to multiply each possible value of X by its corresponding probability and then sum up the products. In this case, we have:

E(X) = (0 x 0.1) + (1 x 0.4) + (2 x 0.4) + (3 x 0.1)

= 0 + 0.4 + 0.8 + 0.3

= 1.4

Therefore, the expected value or the average number of times a customer visits the store in a one week period is 1.4. This means that if we were to observe a large number of customers over a long period of time, we would expect the average number of visits per customer to be approximately 1.4.

The statement Count = Count + 2 assigns the value of the Count variable to itself, incremented by two. Therefore, the answer to the question is B) 25.

We are given the initial value of the Count as 23. The statement Count = Count + 2 assigns the value of the Count variable to itself, incremented by two.

This implies that the value of Count is 23+2= 25 after the statement is executed.

In other words, the right-hand side of the equals sign is evaluated before the value is assigned to the left-hand side of the equals sign.

In this case, the right-hand side is Count + 2, which is equal to 23+2= 25.

The value 25 is then assigned to the variable Count on the left-hand side of the equals sign.

As a result, the value of Count after executing the statement Count = Count + 2 is 25.

Thus, option B) 25 is the correct answer to the given question.

The decimal 5.09 converts to the mixed number 5 & 9/100

This is because the 9 is in the hundredths place.

If you need to convert to an improper fraction, then use the formula

a & b/c = (a*c + b)/c

So,

5 & 9/100 = (5*100+9)/100

5 & 9/100 = (500+9)/100

5 & 9/100 = 509/100

Use triangle bisect or theorem.

Set up proportion:

X/ 2.25 = 4/3

Cross multiply:

3x = 9

Divide both sides by 3:

X = 3

The Risk Matrix lists the relative probability of a risk occurring and the relative impact of the risk occurring.

The Risk Matrix is a tool commonly used in risk management to assess and prioritize risks based on their likelihood of occurrence and potential impact.

It typically consists of a two-dimensional grid, with one axis representing the likelihood of the risk occurring, and the other axis representing the potential impact of the risk.

Each cell in the grid represents a specific level of risk, and is typically color-coded or labeled to indicate the severity of the risk. By using a Risk Matrix.

Organizations can prioritize their risk management efforts by focusing on the risks that are most likely to occur and have the greatest potential impact.

The minimum number of neckless needed to sell to make a profit is 18 thus option (A) is correct.

A difference between two values indicates whether one is smaller, larger, or basically not similar to the other.

In other words, inequality is just the opposite of equality for example 2 =2 then it is equal but if I say 3 =6 then it is wrong the correct expression is 3 < 6.

As per the given,

12n > 135 + 4.50n

In order to make a profit and solve inequality,

12n - 4.50n > 135

7.5n > 135

n > 18

Thus, it needed to sell more than 18 to make a profit.

Step-by-step explanation:

To determine which set of data most likely has a mean closest to 29.5, we need to analyze the shape and position of the histograms in relation to the value 29.5.

Looking at the histograms described:

The first histogram ranges from 9 to 48, and the upward trend starts from 1 and ends at 33, followed by a downward trend. This histogram suggests that there may be values lower than 29.5, which would bring the mean below 29.5.

The second histogram ranges from 15 to 48, with an upward trend from 1 to 30 and then a downward trend. Similar to the first histogram, it suggests the possibility of values lower than 29.5, indicating a mean below 29.5.

The third histogram ranges from 12 to 56, and the upward trend starts from 1 and ends at 32, followed by a downward trend. This histogram covers a wider range but still suggests the possibility of values below 29.5, indicating a mean below 29.5.

The fourth histogram ranges from 15 to 54 and exhibits multiple trends. While it has fluctuations, it covers a wider range and includes both upward and downward trends. This histogram suggests the possibility of values above and below 29.5, potentially resulting in a mean closer to 29.5.

Based on the descriptions, the fourth histogram, with its more varied trends and wider range, is most likely to have a mean closest to 29.5.

To find the equation of the tangent line to the curve y = tan²(2x) at x = π/4, we need to determine the slope of the tangent line at that point and then use the point-slope form of a line to write the equation.

First, let's find the derivative of y with respect to x. Using the chain rule, we have:

dy/dx = 2tan(2x) sec²(2x).

Now, let's substitute x = π/4 into the derivative:

dy/dx = 2tan(2(π/4)) * sec²(2(π/4))

      = 2tan(π/2) * sec²(π/2)

      = 2(∞) * 1

      = ∞.

The derivative at x = π/4 is undefined, indicating that the tangent line at that point is vertical. Therefore, the equation of the tangent line is x = π/4. Note that the equation y = 2/tan(2x) (sec²(2x) + 1/2) is not the equation of the tangent line, but rather the equation of the curve itself. The tangent line, in this case, is vertical.

Answer:

Step-by-step explanation:

Square A:

Area = 225 square feet

side *side = 225

        Side =√225

                 \(=\sqrt{15*15}\)

   Side of square A = 15 ft

Square B:

Area = 400 square feet

Side =√400

       = \(\sqrt{20*20}\)

Side of square B = 20 ft

Use Pythagorean theorem for finding the side of Square C.

Side of square A is the altitude ;  side of square B is the base and side of square C will be the hypotenuse

hypotenuse² = base² + altitude²

                      = 15² + 20²

                       = 225 + 400

                       = 625

hypotenuse = \(\sqrt{625} =\sqrt{25*25}\) = 25 ft

Area of square C = 625 square ft

In short,

Area of square C = area of square B + area of square A

                             = 400 + 225

                             = 625 square ft

A very simple way to know the number of possible combinations in a binary number is given by the next formula:

Now, we should remember that an hexadecimal number contain 16 different digits, from 0 to F. Therefore

Thus, we will need 4 hexadecimal numbers to achieve the same values as a 16-bit number.

The area of the square is the square of its side:

And the area of the rectangle is the product of its lengths by its height:

So, the probability is the area of the square divided by the area of the rectangle:

f(x) = a·(x + 1)·(x - 3)

f(2) = a·(2 + 1)·(2 - 3) = a·3·(-1) = -3·a = -6 --> a = 2

f(x) = 2·(x + 1)·(x - 3)

f(x) = 2·(x^2 - 3·x + x - 3)

f(x) = 2·(x^2 - 2·x - 3)
