The domain and range of the inverse of the function f(x) = 0.5x need to be determined. The domain and range of the inverse function g(x) = 2x are both all real numbers.
To find the domain and range of the inverse of a function, we can swap the roles of x and y in the original function and then solve for y.
The original function is f(x) = 0.5x. Swapping x and y, we get x = 0.5y. Solving this equation for y, we multiply both sides by 2, giving us y = 2x.
The domain of the inverse function, denoted as g(x), is the set of all possible x-values. In this case, the domain of g(x) is the same as the range of the original function f(x). The range of f(x) is all real numbers, so the domain of g(x) is also all real numbers.
Similarly, the range of the inverse function is the set of all possible y-values. In this case, the range of g(x) is the same as the domain of the original function f(x). The domain of f(x) is all real numbers, so the range of g(x) is also all real numbers.
Therefore, the domain and range of the inverse function g(x) = 2x are both all real numbers.

Solve for n. 2n+3/4n = 3/4
Answer: n=3/11
Step-by-step explanation:
1. You want to simplify both sides of the equation.
2n+3/4n=3/4.
(2n+3/4n)=3/4 (combine like terms).
11/4n=3/4.
2. Multiply both sides using 4/11.
(4/11)x(11/4n)=(4/11)x(3/4)
3. You get your answer which is n=3/11.

Step-by-step explanation:
determine Sn given the series: 45 - 56 + 67 - 78 + 89
- 100 + ..... - 342
The given series is an alternating series with a pattern of adding and subtracting consecutive terms. To determine Sn, we need to find the sum of the first n terms of the series. Therefore, the sum of the series is -13,365.
In the given series, each term is obtained by adding 11 to the previous term and then changing its sign. We can observe that the first term is positive (45), the second term is negative (-56), the third term is positive (67), and so on.
To find Sn, we need to determine the number of terms in the series and then calculate the sum. The series ends with -342, so we need to find the position of -342 in the series.
To do this, we can subtract 45 from -342 and divide the result by 11 to find the number of terms. (-342 - 45) / 11 = -297 / 11 = -27. Therefore, the series consists of 27 terms.
To find the sum of the first 27 terms, we can use the formula for the sum of an arithmetic series: Sn = (n/2)(a + l), where n is the number of terms, a is the first term, and l is the last term.
Using the formula, we can calculate Sn as follows: Sn = (27/2)(45 - 342) = (27/2)(-297) = -13,365.
Therefore, the sum of the series is -13,365.

For a hypothesis test using the single-factor ANOVA formula:
The obtained overall F ratio = MS between treatments divided by MS within treatments.
Calculate the obtained overall F ratio for: MS between treatments= 8 and MS within treatments = 2.
Then describe the null hypothesis decision for = .05, df numerator: 3, and df denominator: 4.
Reject of fail to reject null hypothesis?
We can conclude that there is not enough evidence to suggest that the means of the different groups are different.
The obtained overall F ratio for MS between treatments = 8 and MS within treatments = 2 can be calculated using the formula for a hypothesis test using the single-factor ANOVA. The formula is given below: Obtained overall F ratio = MS between treatments/MS within treatments Substituting the values in the above formula, we get, Obtained overall F ratio = 8/2 = 4
The obtained overall F ratio for MS between treatments = 8 and MS within treatments = 2 is 4.Now, let's describe the null hypothesis decision for α = .05, df numerator: 3, and df denominator: 4.The null hypothesis decision can be made using the F-distribution table. Using the table, the critical value of F is 9.49.
Therefore, if the obtained overall F ratio is greater than 9.49, then we reject the null hypothesis. If the obtained overall F ratio is less than or equal to 9.49, then we fail to reject the null hypothesis.Obtained overall F ratio = 4 is less than the critical value of F, i.e., 9.49.Therefore, the null hypothesis is not rejected at α = .05, df numerator: 3, and df denominator: 4.

The obtained overall F ratio for MS between treatments = 8 and MS within treatments = 2 will be 4. The null hypothesis decision for α = 0.05, df numerator: 3, and df denominator: 4 is Fail to reject null hypothesis.
Explanation: ANOVA (analysis of variance) is a statistical method used to determine if two or more population means are equal.
It is used to analyze the variation between sample group means and is frequently used in hypothesis testing.
Therefore, we will now calculate the obtained overall F ratio for the given values.
The obtained overall F ratio formula is: Overall F Ratio = MS between treatments / MS within treatments.
Given, MS between treatments = 8 and MS within treatments = 2.
Therefore, Overall F Ratio = MS between treatments / MS within treatments
= 8/2
= 4
Hence, the obtained overall F ratio for MS between treatments= 8 and MS within treatments = 2 is 4.
The null hypothesis decision for α = 0.05, df numerator: 3, and df denominator: 4 is Fail to reject null hypothesis.
The test statistic value, F, is 3.71. The p-value is greater than 0.05. Therefore, we fail to reject the null hypothesis.

5 x 2 y = 5 3 x - y = 14 which of the following equations is not a result of solving the system of equations by addition?
The equation "6x + y = 29" is not a result of solving the given system of equations by addition.
To solve a system of equations by addition, we aim to eliminate one variable by adding the equations together. Let's analyze the given system of equations:
Equation 1: 5x + 2y = 5
Equation 2: 3x - y = 14
To eliminate the y variable, we can multiply Equation 2 by 2 and add it to Equation 1:
2(3x - y) = 2(14)
6x - 2y = 28
Adding this modified Equation 2 to Equation 1, we get:
(5x + 2y) + (6x - 2y) = 5 + 28
11x = 33
x = 3
Substituting the value of x into either of the original equations, we find that y = -1. Therefore, the solution to the system of equations is x = 3 and y = -1.
Now, let's verify the options to see which equation is not a result of solving the system by addition:
A) 11x = 33 - This equation is derived from adding the two equations together.
B) 6x + y = 29 - This equation is derived from substituting the values of x and y into one of the original equations.
C) 2y = 2 - This equation is derived from isolating the variable y in Equation 1.
D) x = 3 - This equation is derived from solving for x.
Thus, the equation "6x + y = 29" is not a result of solving the system of equations by addition.

Remember: The farther the number is to the right, the smaller it becomes.
Ex. 0.10 is greater than 0.100 since the number is shorter and closer to the ones/whole number spot.

Thomas loaned $6,250 to Cameron at a simple interest rate of 4.12% p.a. for 2 years and 6 months. Calculate the amount of interest charged at the end of the term. Round to the nearest cent
The amount of interest charged at the end of the term is approximately $644.75.
To calculate the amount of interest charged at the end of the term, we can use the simple interest formula:
Interest = Principal * Rate * Time
Principal = $6,250
Rate = 4.12% = 0.0412 (decimal form)
Time = 2 years + 6 months = 2.5 years
Plugging in these values into the formula, we have:
Interest = $6,250 * 0.0412 * 2.5
Calculating this expression:
Interest = $6,250 * 0.0412 * 2.5 = $644.75
Therefore, the amount of interest charged at the end of the term is $644.75 (rounded to the nearest cent).
