The volume of the actual shoe store that Mai's company plans to build is 280,000 ft³.
Based on the given information, Mai created a scale model with a ratio of 1:20. If the volume of the model is 35 ft³, we can find the volume of the actual shoe store by using the ratio.
Since the ratio of the dimensions is 1:20, the ratio of the volumes will be (1:20)³, which is 1:8000. Therefore, to find the volume of the actual shoe store, we can multiply the volume of the model by 8000:
Volume of the actual shoe store = 35 ft³ × 8000 = 280,000 ft³
So, the volume of the actual shoe store that Mai's company plans to build is 280,000 ft³.

the standard deviation of a probability distribution must be:
The standard deviation of a probability distribution must be a non-negative value. It represents the measure of the dispersion or spread of the data in the distribution. The standard deviation quantifies how much the values in the distribution deviate from the mean.
Mathematically, the standard deviation (σ) is calculated as the square root of the variance (σ^2) of the probability distribution. The variance is obtained by calculating the average of the squared differences between each data point and the mean, weighted by their respective probabilities.
The standard deviation provides important information about the shape and characteristics of the distribution. A smaller standard deviation indicates that the data points are closer to the mean, resulting in a more concentrated or less dispersed distribution. Conversely, a larger standard deviation indicates that the data points are more spread out from the mean, resulting in a wider or more dispersed distribution.
The standard deviation of a probability distribution must be a non-negative value and is a measure of the dispersion or spread of the data in the distribution.

When planting a garden, you can choose from five types of tomatoes, two types of peppers, and four types of squash. If you choose only one crop from each category, how many possible garden combinations can you make?
When building a computer, you need to make several choices, such as type of storage, level of memory, and type of processor. You can choose from three types of storage, six levels of storage, and four types of processor. Calculate the number of combinations that you have if these are the only three choices you need to make.
There are 72 possible combinations for the computer choices.For the garden combinations, since you are choosing one crop from each category, you can use the concept of multiplication to determine the total number of combinations.
Number of tomato choices = 5
Number of pepper choices = 2
Number of squash choices = 4
Total number of garden combinations = Number of tomato choices * Number of pepper choices * Number of squash choices
Total number of garden combinations = 5 * 2 * 4 = 40
Therefore, there are 40 possible garden combinations you can make.
For the computer combinations, using the same concept of multiplication:
Number of storage choices = 3
Number of memory level choices = 6
Number of processor choices = 4
Total number of computer combinations = Number of storage choices * Number of memory level choices * Number of processor choices
Total number of computer combinations = 3 * 6 * 4 = 72

Perform the indicated operation. Assume that no denominator is 0. ( x² - x / x -1 ) ( x+1 / x)
To perform the indicated operation, we need to multiply the two fractions: (x² - x)/(x - 1) and (x + 1)/x. To multiply fractions, we multiply the numerators together and the denominators together. Let's multiply the numerators first:
(x² - x) * (x + 1) = x³ + x² - x² - x = x³ - x
Now, let's multiply the denominators:
(x - 1) * x = x² - x
Therefore, the result of the multiplication is:
(x³ - x)/(x² - x)
This expression cannot be further simplified, so the final answer is (x³ - x)/(x² - x).

A clown's face on a balloon is 4 in. tall when the balloon holds 108 in.³ of air. How
much air must the balloon hold for the face to be 8 in. tall?
Assuming the shape of the balloon remains the same, the volume of the balloon is directly proportional to the cube of its height. Therefore, we can use the following proportion:
(air volume)₁ / (height)₁³ = (air volume)₂ / (height)₂³
where:
(air volume)₁ = 108 in.³ (when the height is 4 in.)
(height)₁ = 4 in.
(height)₂ = 8 in.
We can solve for (air volume)₂ as follows:
(air volume)₂ = (air volume)₁ × (height)₂³ / (height)₁³
(air volume)₂ = 108 in.³ × (8 in.)³ / (4 in.)³
(air volume)₂ = 108 in.³ × 64 / 64
(air volume)₂ = 108 in.³
Therefore, the balloon must hold 108 in.³ of air for the clown's face to be 8 in. tall.

QUICKKK!!!! how can you proof or check a point is a solution to a system of two linear equations?
To check to see if a point is a solution to a system of two linear equations, you can plug the points into each equation. If the solution point causes the equation toequal itself, it is correct.
To solve the system of linear equations 3 x minus 2 y = 4 and 9 x minus 6 y = 12 by using the linear combination method, Henry decided that he should first multiply the first equation by –3 and then add the two equations together to eliminate the x-terms. When he did so, he also eliminated the y-terms and got the equation 0 = 0, so he thought that the system of equations must have an infinite number of solutions. To check his answer, he graphed the equations 3 x minus 2 y = 4 and 9 x minus 6 y = 12 with his graphing calculator, but he could only see one line. Why is this?
Henry could only see one line since both lines had the same slope, which means that the graphs of both equations will be identical and hence overlap.
Identify the linear equation?Linear equations in a system 3x + 2y = 4, and 9x + 6y = 12
We must demonstrate why Henry could only make out one line when he plotted the equations 3x-2y=4 and 9x-6y=12 on a graph.
Take the provided linear equation system into consideration.
3x - 2y = 4 ................(1)
9x - 6y = 12 ..................(2)
Due to the fact that equation (2) is a multiple of equation (1), 3 (3x - 2y = 4) = 9x - 6y = 12
The slopes of the provided equations are also same.
Difference with regard to x for equation (1) yields,
additional to equation (2),
With regard to x, we can differentiate to get,
The graphs of both equations will overlap since both lines have the same slope and hence have the same appearance on the graph.

Let x be the age of the person. When the person was born, their parents opened an investment account in their name and deposited $500 into the account.
Let A be the value of the investment account when the person is x years old.
The interest rate is 10% compounded monthly. Then, the monthly interest rate is
\(:r = (10/12)/100 = 0.0083333333\)
The account has earned interest for 12 * x months.
Hence, we have:
\(A = 500(1 + r)^(12x)\)
Now, we can solve for x.
A = 36911.22.
Hence:\(36911.22 = 500(1 + r)^(12x)\)
Take the natural logarithm of both sides to solve for x.
\(ln(36911.22/500) = 12x ln(1 + r)ln(36911.22/500) = 12x(0.0083333333)ln(36911.22/500) = 0.0083333333x\)

The average rate of population growth between 2013 and 2015 is 0.35 million per year. If the population continues to grow at this rate what year will it reach 40 million?
Answer:
2021.
Step-by-step explanation:
The average growth rate between 2013 and 2015 was 0.35. That means it was 0.35/2 = 0.175 per year.
To find in how many years it will reach 40 million:
(40 - 39.1)/0.175 = 5.14
As we can see, it will take 5.14 years for the population to increase from 39.1 to 40 millions.
That means, in 5 years the population will not reach 40 million, but until the end of the 6th year, the population will reach.
That means the population will reach 40 million in 2021 (2015 + 6).

If events A and B are mutually exclusive, with probabilities 0.23 and 0.32 respectively, what is the probability that one, the other, or both events occur, i.e. Pr{A or B}
The probability that one, the other, or both events occur is 0.55.
We have,
If events A and B are mutually exclusive, they cannot occur simultaneously.
Therefore, the probability of both events occurring is 0.
To calculate the probability that one, the other, or both events occur (Pr{A or B}), we can add the individual probabilities of events A and B.
Pr{A or B} = Pr{A} + Pr{B} = 0.23 + 0.32 = 0.55
Therefore,
The probability that one, the other, or both events occur is 0.55.
