A house painter decides how many cans of paint to buy based on the total surface area of the house. The table below shows the surface area, o, in square meters, and the
number of cans of paint, P, used for three different houses

The expression that has the element of A*B*B is Option A - (b,2,3)

Sets are groups of clearly defined objects or elements in mathematics. A set is denoted by a capital letter, and the cardinal number of a set is enclosed in a curly bracket to indicate how many members there are in a finite set.

The "elements" of a set are the objects that make up the collection. Sets are equal if and only if they have the same elements, therefore a = A denotes that 'a' is one of A's elements. For sets, repetition and order are irrelevant.

Given, A={a.b} and B=[1,2,3]

Since the required expression was supposed to have the element of A*B*B the correct option would be A since it has elements b from A, 2 from B, and 3 from B, fulfilling all the required elements.

Step-by-step explanation:

Ricardo has the greatest amount of personal control over his savings. So, correct option is A.

Savings refer to the money he has already set aside or accumulated for college. He has complete control over how much he saves and how he spends it.

Scholarships, grants, and work-study programs are external sources of funding that Ricardo can apply for and receive, but he may not have complete control over the amount of money he receives.

Scholarships and grants are typically awarded based on academic achievement, financial need, or other criteria that are beyond his control. Work-study programs may limit the number of hours he can work or the type of work he can do, and the amount of money he can earn may also be limited.

In contrast, Ricardo can decide how much money he wants to save for college and how he wants to allocate that money towards his expenses. He can also choose to invest his savings in a way that can earn interest or returns, which can help him maximize his savings. Therefore, his personal control over his savings gives him the most flexibility and independence in paying for his college expenses.

So, correct option is A.

The number of cups will be equal to 496.

The sequence in which every next number is the addition of the constant quantity in the series is termed as the arithmatic progression

Here we have the data:-

The bottom row has 61 cups

If there are 16 total rows

The number of the cups will be calculated as:-

\(S_n=\dfrac{n(a_1+a_n)}{2}\)

Here a1 is first term 1

an is last term 2

n is the total number of the rows

By putting the values in the question we will get:-

\(S_n=\dfrac{16(1+61)}{2}=\dfrac{16\times 62}{2}=496\ cups\)

Answer:

Step-by-step explanation:

It's the only combination left

The standard deviation for the given data set is approximately 7.68 (rounded to two decimal places).

To find the standard deviation for the given data, we can follow these steps:

Understanding the process

1. Calculate the mean (average) of the data set.

2. Subtract the mean from each data point and square the result.

3. Calculate the mean of the squared differences.

4. Take the square root of the mean to obtain the standard deviation.

Calculating the standard deviation

1. Find the mean of the data set:

  Mean = (14 + 7 + 2 + 1 + 0 + 21) / 6 = 45 / 6 = 7.5

2. Subtract the mean from each data point and square the result:

  (14 - 7.5)^2 = 45.0625

  (7 - 7.5)^2 = 0.25

  (2 - 7.5)^2 = 30.25

  (1 - 7.5)^2 = 42.25

  (0 - 7.5)^2 = 56.25

  (21 - 7.5)^2 = 184.5

3. Calculate the mean of the squared differences:

  Mean of squared differences = (45.0625 + 0.25 + 30.25 + 42.25 + 56.25 + 184.5) / 6 = 58.7708

4. Take the square root of the mean to obtain the standard deviation:

  Standard deviation = sqrt(58.7708) ≈ 7.68

Therefore, the standard deviation for the given data set is approximately 7.68 (rounded to two decimal places). The standard deviation measures the spread or dispersion of the data points around the mean. In this case, it indicates how much the individual data points deviate from the average value of 7.5. A larger standard deviation suggests a greater variability in the data, while a smaller standard deviation indicates a more clustered or homogeneous data set.

Subtract 6x from both sides to isolate y which is also called subtraction property of equality.

so 5y = -6x -15

Now you divide both sides by 5 which is called division property of equality.

You now have y = -6/5x - 3

y= -6/5x -3 is the slope intercept form of the standard form equation of 6x + 5y = -15.

Answer:

Part A

a. There is not sufficient sample evidence to conclude that the full-time placement rate is now less than 87% because the p-value is greater than 0.05

Part B

\(\hat Y\) = 17.9·(x) + 1.6

Part C

The teen pregnancy rate in Florida is 6.54

Step-by-step explanation:

The percentage of graduates that find full-time employment in their fields within the first year of graduation = 87%

The significant level of the hypothesis test = 5% = 0.05

The p-value = 0.07

Given that the testing conditions are met, we have;

The p-value is larger than the significant level of 0.05, therefore, it cannot be concluded that there is significant difference between the two rates

Therefore;

There is not enough statistical evidence available to come to a conclusion that the placement rate of full-time students has reduced below the given 87% because from the statistics, the p-value is larger than 0.05.

Part B

Number of Pages, x; 7, 12, 4, 14, 25, 30

Cost, y; 128, 213, 75, 250, 446, 540

The regression analysis formula is;

Y = a + b·X

We have;

\(b = \dfrac{N\sum XY - \left (\sum X \right )\left (\sum Y \right )}{N\sum X^{2} - \left (\sum X \right )^{2}}\)

∴ b = (6×34602-92×1652)/(6×1930 - 92²) ≈ 17.852

\(a = \dfrac{\sum Y - b\sum X}{N}\)

a = (1652 - 17.852 × 92)/6 ≈ 1.6

∴ Y ≈ 17.9·(x) + 1.6

Part C

The given regression model is y = 4.3 + 1.4(x)

Therefore, at x = 1.6, we get;

y = 4.3 + 1.4 × 1.6 = 6.54

The suggests that the teen pregnancy rate in Florida is 6.54.
