The investment's expected return is 5.95%.

The expected return of an investment is calculated by multiplying the probabilities of each possible return by their respective returns and summing them up. In this case, Gautney Enterprises has provided the probabilities and returns for the investment. By applying the formula, we find that the expected return is 5.95%.

To calculate the standard deviation, we need to determine the variance first. The variance is computed by taking the difference between each possible return and the expected return, squaring those differences, multiplying them by their respective probabilities, and summing them up. Once we have the variance, the standard deviation is simply the square root of the variance. The standard deviation measures the degree of risk associated with an investment.

In this scenario, the expected return of the investment is 5.95%, but we need to consider the standard deviation as well to assess the risk. If the standard deviation is high, it indicates a greater level of uncertainty and potential volatility in returns. A low standard deviation implies a more stable investment.

Without the specific values for each return and their respective probabilities, we cannot calculate the exact standard deviation. However, Gautney Enterprises should compare the calculated expected return and the associated standard deviation to their risk tolerance and investment objectives. If the expected return meets their desired level of return and the standard deviation aligns with their risk appetite, they may consider investing in this security.

Answer: 21.21 meters

Step-by-step explanation:

Hi, to answer this, first we have to calculate the circumference (C) of the wheel:

C = π x diameter

Replacing with the values given:

C = π x 45 = 141.37 cm

Then we multiply it by the number of revolutions:

141.37 x 15 = 2,120.6 cm

Since  

1 cm = 0.01 m

2,120.6 x 0.01 = 21.21 meters

To test the hypothesis of mean differences in artificially sweetened drink consumption among BMI groups, assuming a normal distribution, the researcher might use a one-way ANOVA.

The one-way ANOVA compares the means of three or more independent groups and determines if there are statistically significant differences among them. In this case, the BMI groups (normal weight, overweight, and obese) represent the independent groups, and the number of artificially sweetened drinks consumed is the dependent variable. By conducting a one-way ANOVA, the researcher can assess if there are significant differences in mean consumption among the BMI groups and draw conclusions regarding their hypothesis.

Step-by-step explanation:

Dodie's triangular plot with 160 rose plants will have 12 rows.

To solve it,

Assigning a variable to the number of rows we want to find. Assume that this variable is "n".

Since there are 5 more plants in each row than in the previous row,

We can use an arithmetic sequence to represent the number of plants in each row.

Specifically, the first row will have 1 plant, and the second row will have

1 + 5 = 6 plants, the third row will have 1 + 5 + 5 = 11 plants, and so on.

The formula for an arithmetic sequence is,

an = a1 + (n-1)d

Where an is the nth term of the sequence,

a1 is the first term,

And d is a common difference.

Using this formula, we can write an expression for the total number of plants in all n rows,

160 = n/2 (2 + (n-1)5)

Simplifying this equation, we get,

160 = 2.5n² + 2.5n - 5

Now we can solve for n using the quadratic formula,

n = (-2.5 ± √(2.5²+ 4(2.5)(165)))/(2(2.5))

After simplifying this equation, we get two solutions,

n = -13.2 and n = 12.2.

Since we can't have a negative number of rows, we'll take the positive solution, n = 12.2.

Now, since we can't have a fraction of a row, we'll round down to the nearest integer.

Therefore, Dodie's plot will have 12 rows.

Answer:

Step-by-step explanation:

The markup value over the each order of cookies is 300%. Thus option B is correct.

According to the statement

we have given that the James costs $4 to make an order of dozen cookies and selling prices is $16 and we have to calculate the markup on the order of cookies.

So, For this purpose, we know that the

Markup formula calculates the amount or percentage of profits derived by the company over the product's cost price.

The formula to calculate markup is :

Markup = (selling cost - production cost / production cost) *100

So, Substitute the formula in it then

Markup = (selling cost - production cost / production cost) *100

Here selling cost = $16 and production cost is $4

So,

Markup = (selling cost - production cost / production cost) *100

Markup = (16 - 4 / 4) *100

Markup = 3 *100

Markup = 300%.

So, The markup value over the each order of cookies is 300%. Thus option B is correct.

C) The sum of the first 2 terms after the fourth term.

Probability that both the person own the dog is equal to 0.0225.

The likelihood that an event will occur is measured by probability. It is difficult to provide a complete prediction for many events. Using it, we are only able to estimate the likelihood that an event will occur, or the chance that it will. Between 0 and 1, where 1 denotes a certain event and 0 denotes an impossibility, is the range of probabilities.

Let event A denotes that a person own dog,

P(A) = 15% =15/100 = 0.15

If we pick two people at Random then Probability that they both own dog

= P(A)*P(A)

= 0.15 * 0.15

The input and the output of a function are key components in understanding how a function operates. The input refers to the value or values that are given to the function as an argument, while the output refers to the result or results that the function returns after processing the input.

In other words, the input is what you provide to the function, and the output is what you get in return. The input can be a single value or a set of values, depending on the requirements of the function. The output can also be a single value or a collection of values, again depending on the function's purpose.

It's important to note that the input and output of a function are not always the same. The function may perform calculations or transformations on the input, and the output may be different from the input. This transformation is what gives functions their ability to perform specific tasks and solve problems.

In summary, the input is what you give to a function, and the output is what you get in return after the function processes the input.

Step-by-step explanation:

The length of crossbar that Sasha need to complete the kite is equal to √8 units.

By critically observing the image of the kite shown below, we can logically deduce that the crossbar and the two (2) given lengths formed a right-angled triangle as illustrated by the right angle symbol between the two given sides.

In order to determined, we would have to apply Pythagorean's theorem. Mathematically, Pythagorean's theorem is given by this mathematical expression:

a² + b² = c²

Where:

a, b, and c represents the side lengths of a right-angled triangle.

Substituting the given parameters into Pythagorean's theorem, we have the following;

Situation can be modeled by a linear function, A situation that involves a constant rate of change can be modeled by a linear function.

A linear function is a mathematical representation of a relationship between two variables that forms a straight line when plotted on a graph. It is characterized by a constant rate of change between the variables.

In a linear function, the dependent variable (y) changes at a constant rate for every unit change in the independent variable (x). This means that as x increases or decreases by a fixed amount, y also changes by a consistent amount.

Situations that exhibit a constant rate of change can be effectively modeled by linear functions.

Examples include scenarios such as distance traveled over time at a constant speed, the growth of a bank account with a fixed interest rate, or the cost of an item per unit.

In these cases, the relationship between the variables can be represented accurately using a linear equation or function.
