Answer:
Slope is rise over run. so, if you have a line of best fit, you go from one point to the next. Up 1 would be 1 down one would be -1. right 1 would also be 1, left one is -1. After you get the rise over run (Say it's 5/4) then you divide rise over run. 1.25 is the slope of this one. post this question with a picture of a graph and i'll gladly help

Solve the inequality and write the solution in set-builder notation. r - 8 <= 7
So on solving the provided question, we can say that inequality equation will be as follows r - 8 <= 7 r<=15 or r >= -15
What is inequality?An inequality in mathematics is a relationship between two expressions or values that is not equal. Thus, imbalance leads to inequality. An inequality creates the link between two values that are not equal in mathematics. Egality is distinct from inequality. When two values are not equal, most commonly use the not equal sign (). Different inequalities are used to contrast values, no matter how little or large. Many simple inequalities may be resolved by modifying the two sides until the variables are all that remain. But a number of things contribute to inequality: Negative values on both sides are divided or added. Trade off the left and right.

In the equation y = $7.20x + $790, "y" represents Select one: A. variable costs/unit. B. total fixed costs. C. total costs. D. none of the above
In the equation y = $7.20x + $790, "y" represents the total cost. An equation is a mathematical statement that shows the relationship between two or more variables. In this equation, there are two variables - "x" and "y". The variable "x" represents the number of units produced or sold, while "y" represents the total cost.
The coefficient of "x" in the equation, which is 7.20, represents the variable cost per unit. This means that for each unit produced or sold, there is an additional cost of $7.20. The constant term, which is $790, represents the total fixed costs. Fixed costs are those costs that do not vary with the number of units produced or sold.To find the total cost of producing or selling a certain number of units, we can plug in the value of "x" into the equation and solve for "y". For example, if we want to find the total cost of producing 100 units, we can substitute x=100 into the equation:
y = $7.20(100) + $790
y = $720 + $790
y = $1510
Therefore, the total cost of producing 100 units is $1510. In summary, "y" represents the total cost in the given equation, which is determined by both fixed and variable costs.
In the equation y = $7.20x + $790, "y" represents option C: total costs. This equation has two components: "$7.20x" represents the variable costs per unit, where x is the number of units, and "$790" represents the total fixed costs. By adding these two components together, you get the total costs (y) for producing x units.

Matrix is\(a = [2512-60-29]\). Now, we need to find c, d, and c−1 such that a=cdc−1. For this, we can use the concept of matrix multiplication.
In order to multiply two matrices A and B, the number of columns in A must be equal to the number of rows in B.
Therefore, we can separate the matrix a into two matrices c and d such that \(a=cdc-1\) as follows: \(c = [ 2 1 - 1 2 ] , d = [ 5 0 0 -3 ]\) and \(c^-1 = [ 2 1 1 2 ]\) .

a teacher is experimenting with computer-based instruction. in which situation could the teacher use a hypothesis test for a population mean? she gives each student a pretest. then she teaches a lesson using a computer program. afterwards, she gives each student a posttest. the teacher wants to see if the difference in scores will show an improvement.
In this situation, the teacher could use a hypothesis test for a population means to determine if the computer-based instruction led to a statistically significant improvement in the student's test scores. The population in this case would be the entire class of students, and the mean would represent the average difference in test scores between the pretest and posttest.
The teacher can use a hypothesis test for a population means in the following situation:
1. Determine the population: The teacher's population consists of all the students who participated in the experiment.
2. Calculate the mean pretest score: The teacher will compute the average score of all the students' pretest results.
3. Implement computer-based instruction: The teacher teaches a lesson using a computer program.
4. Conduct a posttest: After the lesson, the teacher administers a posttest to each student.
5. Calculate the mean post-test score: The teacher will compute the average score of all the students' post-test results.
6. Formulate a null hypothesis: The null hypothesis states that there is no significant difference between the pretest and posttest mean scores. In other words, computer-based instruction did not have a significant impact on the students' performance.
7. Conduct a hypothesis test for a population mean: The teacher will use a statistical test, such as a t-test, to compare the pretest and posttest mean scores. This test will determine whether there is a significant difference between the two means that suggests the computer-based instruction had a positive effect on the student's performance.
8. Interpret the results: If the hypothesis test shows a significant difference between the pretest and posttest mean scores, the teacher can conclude that the computer-based instruction likely had a positive impact on the students' learning. Otherwise, the null hypothesis cannot be rejected, and the teacher may need to explore other instructional methods or factors that could have influenced the results.

Derek can deposit $14,455.00 on each birthday beginning with his 27.00 th and ending with his 68.00 th. What will the rate on the retirement account need to be for him to have $3,793,695.00 in it when he retires? Answer format: Percentage Round to: 2 decimal places (Example: 9.24%,% sign required. Wil accept decimal format rounded to 4 decimal places (ex: 0.0924))
To have $3,793,695.00 in his retirement account when he retires, Derek would need the rate on the account to be approximately 5.89%.
To calculate the required rate on Derek's retirement account, we can use the formula for the future value (FV) of an annuity:
\(FV = P * [(1 + r)^n - 1] / r\)
Where:
FV is the desired future value
P is the amount deposited on each birthday
r is the interest rate per period
n is the total number of periods (number of birthdays)
In this case, the desired future value (FV) is $3,793,695.00, the amount deposited on each birthday (P) is $14,455.00, and the total number of periods (n) is the difference between Derek's final and initial birthday, which is 68 - 27 = 41.
We need to solve for the interest rate (r). Rearranging the formula:
\(r = [(FV / P) / [(1 + r)^n - 1]]\)
Substituting the given values, we have:
\(r = [(3,793,695.00 / 14,455.00) / [(1 + r)^{41} - 1]]\)
We can use numerical methods or trial and error to find the value of r that satisfies the equation. By using these methods, the approximate value of r is found to be 0.0589 or 5.89%.
Therefore, Derek would need the rate on his retirement account to be approximately 5.89% for him to have $3,793,695.00 in it when he retires.

What is the annual interest rate (APR) required for $22,500 to accumulate to $50,000 in 14 years with interest compounded semi-annually?
An annual interest rate (APR) of approximately 6.35% would be required for $22,500 to accumulate to $50,000 in 14 years with interest compounded semi-annually.
To determine the annual interest rate (APR) required for $22,500 to accumulate to $50,000 in 14 years with interest compounded semi-annually, we can use the formula for compound interest:
A = P(1 + r/n)^(nt)
Where:
A = the final amount ($50,000)
P = the principal amount ($22,500)
r = the annual interest rate (APR)
n = the number of times interest is compounded per year (2 for semi-annual compounding)
t = the number of years (14)
We can rearrange the formula to solve for r:
r = ( (A/P)^(1/(nt)) ) - 1
Substituting the given values into the formula, we have:
r = ( (50000/22500)^(1/(2*14)) ) - 1
r ≈ 0.0635
To express the annual interest rate as a percentage, we can multiply by 100:
r ≈ 6.35%
Therefore, an annual interest rate (APR) of approximately 6.35% would be required for $22,500 to accumulate to $50,000 in 14 years with interest compounded semi-annually.

The mean time to failure for an electrical component is given by;
M = ∫3 (1-0.37 t)¹.² dt
Determine the mean time to failure.
The mean time to failure, based on the given integral ≈ 2.180.
To determine the mean time to failure, we need to evaluate the integral:
M = ∫3 (1 - 0.37t)^1.2 dt
Let's calculate the integral:
M = ∫3 (1 - 0.37t)^1.2 dt
Using the power rule for integration, we can rewrite the integrand:
M = ∫3 (1 - 0.37t)^(6/5) dt
Now, let's integrate using the power rule:
M = [(-5/6)(1 - 0.37t)^(6/5+1)] / (6/5+1) + C
Simplifying the expression:
M = [-5/6(1 - 0.37t)^(11/5)] / (11/5) + C
M = (-5/6)(1 - 0.37t)^(11/5) * (5/11) + C
Now, we need to evaluate the integral from 0 to 3:
M = [(-5/6)(1 - 0.37*3)^(11/5) * (5/11)] - [(-5/6)(1 - 0.37*0)^(11/5) * (5/11)]
Simplifying further:
M = [(-5/6)(1 - 1.11)^(11/5) * (5/11)] - [(-5/6)(1 - 0)^(11/5) * (5/11)]
M = [(-5/6)(-0.11)^(11/5) * (5/11)] - [(-5/6)(1)^(11/5) * (5/11)]
M = [(-5/6)(-0.11)^(11/5) * (5/11)] - [(-5/6)(1) * (5/11)]
M = [-5/6(-0.11)^(11/5)] - [-5/6(5/11)]
M = [-5/6(-0.11)^(11/5)] + [25/66]
Finally, we can calculate the mean time to failure by evaluating the expression:
M ≈ 2.180

mrs hough is building a raised garden next to her 13.5 ft fence so she only needs fencing to go around the other 3 sides. if the area of the garden is 121.5 sw ft how much fencing does she need
Mrs. Hough would need 31.5 feet of fencing for the other three sides of the garden.
To calculate the amount of fencing needed for Mrs. Hough's raised garden, we first need to determine the dimensions of the garden.
Since the garden is next to a 13.5 ft fence, we know that one side of the garden is 13.5 ft.
Let's assume the other two sides of the garden have lengths x and y.
The area of the garden is given as 121.5 sq ft, so we have the equation:
x × y = 121.5
To find the dimensions of the garden, we can solve this equation. One possible solution is x = 9 ft and y = 13.5 ft.
Therefore, the dimensions of the garden are 9 ft by 13.5 ft.
Now, to calculate the amount of fencing needed, we add up the lengths of the three sides (excluding the side next to the fence):
Fencing needed = x + y + x = 9 ft + 13.5 ft + 9 ft = 31.5 ft
Mrs. Hough would need 31.5 feet of fencing for the other three sides of the garden.
