Based on the distribution of the points on the residual plot, where the points are randomly dispersed and shows no obvious trend or pattern, then we can conclude that a Least Square Regression model is appropriate for the data .

The graph of a residual plot is used to Analyse the the appropriateness of a linear regression to model a given data set. The residual values are plotted against the independent variable in other to make a residual plot of the data.

The arrangement of the points on the residual graph is key to making a decision on the model.

Therefore, since the residual plot produced shows a random distribution of the residual values, then the least square regression model is appropriate for the data.

Using the amount of Jim's money donated, we found that the percentage of a person's savings a company donate is 14%.

What is meant by percentage?

A percentage is a figure or ratio stated as a fraction of 100 in mathematics. Frequently, it is indicated with the percent sign, "%". If we need to calculate a percentage of a number, we should divide it by its entirety and then multiply it by 100. The percentage, therefore, refers to  parts per hundred. Per 100 is what the word per cent means. A dimensionless relationship between two numbers can be represented in a variety of ways, such as through ratios, fractions, and decimals.

Given, the money saved by Jim = $1250

Money donated by the company in Jim's name = $175

We are asked to find the percentage of a person's savings a company donate.

For this, we have to find what percentage of $1250 is $175.

Percentage = (Money donated / Total savings) * 100

                  = ( 175 / 1250) * 100 = 14%

Therefore the percentage of a person's savings a company donate is 14%.

A uniform random variable's density function is f(y) = 1 for y 1 and 0 otherwise. F(y) = 0 for y 0, F(y) = y for 0 y 1, and F(y) = 1 for y > 1 define the distribution function.

A uniform random variable's density function is f(y) = 1 for y 1 and 0 otherwise. Accordingly, the likelihood of any specific outcome of y is the same, and the likelihood of any range of outcomes is equal to the length of the range. F(y) = 0 for y 0, F(y) = y for 0 y 1, and F(y) = 1 for y > 1 define the distribution function. Accordingly, the length of the range multiplied by the likelihood of any specific occurrence yields the cumulative probability of any range of outcomes. Since the likelihood of any specific result in that range is 1 and the range's length is 0.5, for instance, the cumulative probability of 0 y 0.5 is 0.5. Since the likelihood of any given result within that range is still 1, but the range's length is 0.5, the cumulative probability of 0.5 y 1 is 0.75. The chance of any range of outcomes for y1 and y2 if they are independent random variables both having the uniform(0,1) distribution is just the sum of their respective cumulative probabilities.

Step-by-step explanation:

Let's solve the given questions step by step:

1. Determine the equation of f:

From the given information, we know that the turning point of f is (1, 4). The general form of a quadratic function is f(x) = ax^2 + bx + c. We are given that f(x) = a(x + p)^2 + q, so let's substitute the values:

f(x) = a(x + p)^2 + q

Since the turning point is (1, 4), we can substitute x = 1 and f(x) = 4 into the equation:

4 = a(1 + p)^2 + q

This gives us one equation involving a, p, and q.

2. Determine the equation of g:

The equation of g is given as g(x) = 0.3x + p1.

3. Determine the coordinates of the x-intercept of g:

The x-intercept is the point where the graph of g intersects the x-axis. At this point, the y-coordinate is 0.

Setting g(x) = 0, we can solve for x:

0 = 0.3x + p1

-0.3x = p1

x = -p1/0.3

Therefore, the x-intercept of g is (-p1/0.3, 0).

4. For which values of x will f(x) ≥ g(x)?

To determine the values of x where f(x) is greater than or equal to g(x), we need to compare their expressions.

f(x) = a(x + p)^2 + q

g(x) = 0.3x + p1

We need to find the values of x for which f(x) ≥ g(x):

a(x + p)^2 + q ≥ 0.3x + p1

Simplifying the equation will involve expanding the square and rearranging terms, but since the equation involves variables a, p, and q, we cannot determine the exact values without further information or constraints.

To summarize:

We have determined the equation of f in terms of a, p, and q, and the equation of g in terms of p1. We have also found the coordinates of the x-intercept of g. However, without additional information or constraints, we cannot determine the exact values of a, p, q, or p1, or the values of x for which f(x) ≥ g(x).

Answer:

\(beinggreat78~here~to~help~you~learn!\)

When doing short equations like this, you want to use P.E.M.D.A.S. That just means you want to use parentheses first, exponents second, multiply third, divide fourth, add fifth, and subtract last. In this case, since there are no parentheses, or subtraction, or exponents, we cross those three out, and make multiplication our top priority. But, what exactly does seven p mean? p is an assigned, substituted number. Sometimes people will use p instead of x as subs, but it really does not matter. So now that we have enough information, let's start.

\(7p=7 * number(In~this~case,~6)\)

\(7 * 6 = 42\)

The next step is to divide q(12) by three. Before adding, you want to divide, because it is your second-top-priority.

\(\frac{q}{3} = \frac{12}{3}~which~is~4\)

Lastly, add the quotient and the product together.

\(7p(42) + \frac{q}{3} (4) = 46\)

And we are done! The result is 46, so that means your answer is D! Yay!

Answer:

Step-by-step explanation:

1.

\(\frac{48}{8} + 2^{3} = 6 + 8 = 14\)

\(5 + 3^2 = 5 + 9 = 14\)

2.

\(9^{2} - 7^{2} = 81 - 63 = 18\)

\(\frac{20}{7-2} = \frac{20}{5} = 4\)

3.

\(\frac{150}{5^2} = \frac{150}{25} = 6\)

\(30 - 4^{2} - 12 = 30 - 16 - 12 = 30 - 28 = 2\)

4.

\(\frac{8 - 7}{2} - 12 = 0.5 - 12 = -11.5\)

\(22 - 2 * 3 = 22 - 6 = 16\)

Answer:

first and fourth

Step-by-step explanation:

Equate and compare both sides of the equations. If both sides are equal then the equation is true.

48 ÷ 8 + 2³ = 6 + 8 = 14

right side = 5 + 3² = 5 + 9 = 14

This is a true equation

---------------------------------------

9² - 7² = 81 - 49 = 32

right side = 20 ÷ (7 - 2) = 20 ÷ 5 = 4

This is not a true equation

---------------------------------------

\(\frac{150}{5^2}\) = \(\frac{150}{25}\) = 6

right side = 30 - 4² - 12 = 30 - 16 - 12 = 14 - 12 = 2

This is not a true equation

--------------------------------------------------

\(\frac{8(7)}{2}\) - 12 = \(\frac{56}{2}\) - 12 = 28 - 12 = 16

right side = 22 - 2 × 3 = 22 - 6 = 16

The direct labor cost included in the Preble Company's flexible budget for March is $819,000.

To find the direct labor cost included in the company's flexible budget for March, we shall estimate the actual direct labor cost incurred during the period.

Given:

Actual production and sales =n26,600 units

Actual direct labor rate = $13.00 per hour

Actual direct labor hours worked = 63,000 hours

Direct labor cost = Actual direct labor rate × Actual direct labor hours worked

Direct labor cost = $13.00/hour × 63,000 hours

Direct labor cost = $819,000

Hence, the direct labor cost included in the company's flexible budget for March would be $819,000.
