Answer:

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.

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?

Answers

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.

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)

Perform the following test of hypothesis. H0: μ 10.70, H1: μ # 10.70, n = 47, t = 12.234, = H0 is
"

Answers

Based on the given information, we have sufficient evidence to conclude that the population mean (μ) is not equal to 10.70.

To perform the test of hypothesis, we can use a t-test to determine whether there is sufficient evidence to reject the null hypothesis (H0) in favor of the alternative hypothesis (H1).

The given hypotheses are:

H0: μ = 10.70 (null hypothesis)

H1: μ ≠ 10.70 (alternative hypothesis)

The sample size is n = 47, and the test statistic is t = 12.234.

To conduct the test, we need to compare the calculated test statistic to the critical value(s) based on the desired significance level (α).

The steps to perform the hypothesis test are as follows:

Step 1: Set the significance level (α)

Let's assume a significance level of α = 0.05. This means we want to be 95% confident in our decision.

Step 2: Determine the critical value(s)

Since the alternative hypothesis is two-sided (μ ≠ 10.70), we need to find the critical values for a two-tailed t-test.

Since n = 47, we have n - 1 = 46 degrees of freedom (df). Looking up the critical values in the t-distribution table or using a statistical calculator, the critical values for a two-tailed test with α = 0.05 and df = 46 are approximately ±2.013.

Step 3: Calculate the p-value

The p-value is the probability of obtaining a test statistic as extreme as the one observed (t = 12.234), assuming the null hypothesis is true.

Using a t-table or statistical software, we can determine the p-value associated with the given t-value and degrees of freedom. The p-value turns out to be very small (p < 0.001).

Step 4: Make a decision

If the p-value is less than the significance level (α), we reject the null hypothesis. Otherwise, we fail to reject the null hypothesis.

Since the p-value is smaller than α (p < 0.001), we reject the null hypothesis (H0).

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

Answers

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).

write the equation of a function whose parent function, f(x) = x 8, is shifted 2 units to the right.

Answers

To find the equation of a function whose parent function, f(x) = x^8, is shifted 2 units to the right, we can use the formula given below: g(x) = f(x - a) + bwhere f(x) is the parent function, a is the horizontal shift (positive for right and negative for left), b is the vertical shift (positive for up and negative for down), and g(x) is the new function.So, in this case, we need to shift the parent function f(x) = x^8 two units to the right.

This means that a = 2 and b = 0 (since there is no vertical shift).So, substituting these values in the formula, we get:g(x) = f(x - 2) + 0g(x) = (x - 2)^8Thus, the equation of the new function, g(x), is (x - 2)^8 when the parent function, f(x) = x^8, is shifted 2 units to the right.

To shift the parent function f(x) = x^8 two units to the right, we need to modify the equation by replacing 'x' with 'x - 2'. This will shift the graph horizontally to the right by 2 units.

Therefore, the equation of the shifted function, let's call it g(x), becomes:

g(x) = (x - 2)^8

To shift the parent function, f(x) = x^8, two units to the right, we can use the transformation equation:

g(x) = f(x - h)

where h represents the horizontal shift. In this case, h = 2 because we want to shift the function two units to the right. Substituting the values into the equation, we get:

g(x) = (x - 2)^8

Therefore, the equation of the function after shifting the parent function, f(x) = x^8, two units to the right is g(x) = (x - 2)^8.

The given parent function is f(x) = x 8. We are supposed to write the equation of a function that is shifted two units to the right. It can be done by taking a new function g(x) and writing it as g(x) = f(x − 2).

Therefore, the equation of the new function g(x) is g(x) = (x − 2)8.

Step-by-step explanation: The given parent function is f(x) = x 8. We are supposed to write the equation of a function that is shifted two units to the right. It can be done by taking a new function g(x) and writing it as g(x) = f(x − 2).

The value of f(x) = x 8

Write it as follows:

when x is 0, 0 8 = 0 and

when x is 1, 1 8 = 8.

Now, we can write the equation for g(x) by using f(x) = x 8.

We have g(x) = f(x − 2)

= (x − 2)8.

Therefore, the equation of the new function g(x) is g(x) = (x − 2)8.

Then describe the null hypothesis decision for = .05, df numerator: 3, and df denominator: 4.

Reject of fail to reject null hypothesis?

Answers

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.
