Nia's original class average was 89%. After increasing it by 3%, she now has a 92% in her math class.
1. Let's assume Nia's original class average was X.
2. She increased her class average by 3%, which can be represented as X + (3/100)X.
3. According to the question, X + (3/100)X = 92.
4. Simplifying the equation, we have (103/100)X = 92.
5. To find X, we divide both sides of the equation by (103/100): X = (92 * 100) / 103.
6. Calculating the value, X ≈ 89.32.
7. Therefore, Nia's original class average was approximately 89.32%.
8. After increasing it by 3%, her new class average is 89.32% + (3/100) * 89.32% ≈ 92%.
Note: The values have been rounded for simplicity.

The mid point of the line segment is (-2, 5 / 2).
How to find the mid point of a line segment?The midpoint of a line segment is a point that lies exactly halfway between two points.
Therefore, let's find the mid point of the line segment indicated above.
Hence, using (-4, 0) and (0, 5)
Hence,
mid point = (x₁ + x₂ / 2, y₁ + y₂ / 2)
Therefore,
mid point = (0 - 4 / 2, 5 + 0 / 2)
mid point = (-4 /2, 5 / 2)
mid point = (-2, 5 / 2)

The number 3.97 is very close to the whole number 4. Therefore, the difference of 4.3 - 3.97 is about 0.33. So, the difference of 4.3 - 3.97 is less than 1.
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.

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.

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).

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.
