Arthur is interested in the effects of sleep deprivation usage on number of calories consumed. He asks a group of 20 college students to spend the night in the sleep lab under one of these conditions: no sleep, 2 hours of sleep, 4 hours of sleep, 6 hours of sleep, or 8 hours of sleep. Arthur measures how many calories are consumed by the students in the sleep lab, which is stocked with various food items. After collecting these data, Arthur performs an ANOVA and finds that he can reject the null hypothesis. On the basis of this, what does Arthur know

Answers

Answer:

Arthur knows that there is a difference among the groups somewhere, but he does not know where

Step-by-step explanation:

An ANOVA test is a test to find out whether the results of an experiment or a survey are significant or not. ANOVA test helps the researcher or the experimenter to decide whether they reject the null hypothesis or accept the alternate hypothesis in the experiment. In ANOVA test, the experimenter wants to find if there is a difference between them or not.

In the context, Arthur is doing a study and he wishes to find out effect of a sleep deprivation on the number of the calories that people consumed. He collects some data from his subject group from the sleep lab and after running the ANOVA test, he finds out that he can reject the null hypothesis. So on this basis, Arthur knows that there is some basic difference among the members of the group somewhere, but he does not know where actually the difference is.

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.

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).

determine Sn given the series: 45 - 56 + 67 - 78 + 89
- 100 + ..... - 342

Answers

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.

Solve for n. 2n+3/4n = 3/4

Answers

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.

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.

How would each of these franchise taxes affect the firm's long-run supply curve? The Federal Motor Carrier Safety Administration (FMCSA) along with state transportation agencies in 38 states administer interstate trucking licenses through a Single State Registration System. However, the registration process is complex, time consuming, and expensive. There are many fees and costly regulations that a trucker or firm must meet to operate. For example, for a large truck, the annual federal interstate registration fee can exceed $8,000. These largely lump-sum costswhich are not related to the number of miles drivenhave increased substantially in recent years. What effect do these new fixed costs have on the trucking market price and quantity? Are individual firms providing more or fewer trucking services? Does the number of firms in the market rise or fall? The Challenge Solution suggests the market price will increase and the market quantity will decrease.
