Step-by-step explanation:

There are 1440 ways for 8 people to be seated in a round table if persons A and B must sit next to each other with no rules about their respective position.

There are a few steps to figuring out how many ways 8 people can be seated in a round table if persons A and B must sit next to each other.

Step 1: Consider persons A and B as one unit.

By considering both person A and B as one person, that there are now 7 available chairs to be seated around the table.

Step 2: Calculate the number of ways to arrange these 7 units around the table.

Since it is a round table, the number of ways is (7-1)! = 6! = 720.

Step 3: Consider the fact that person A and B can be arranged in 2 different ways within their unit (either A is on the left and B is on the right, or vice versa).

We have no rules about the sequence of person A and B's sits, then we can consider that they can choose 2 more options about their own position. This means that the total number of ways to seat the 8 people is 720 * 2 = 1440.

So, the answer is that there are 1440 ways for 8 people to be seated in a round table if persons A and B must sit next to each other.

Answer:

The difference is 4/6

2 1/6 - 1 3/6 = 4/6

The point estimate of the difference in the population mean exercised between underclassmen and upperclassmen is 0.16.


To find the point estimate of the difference in the population mean exercised between underclassmen and upperclassmen, you need to subtract the sample mean of underclassmen from the sample mean of upperclassmen.

Sample mean of upperclassmen = 0.76
Sample mean of underclassmen = 0.60

Point estimate = Sample mean of upperclassmen - Sample mean of underclassmen
Point estimate = 0.76 - 0.60
Point estimate = 0.16


The point estimate of the difference in the population mean exercised between underclassmen and upperclassmen is 0.16, which indicates that on average, upperclassmen exercised 0.16 hours more than underclassmen in the past 24 hours.

Answer:

\( \huge{ \bold{ \boxed{ \tt{n = 2}}}}\)

Step-by-step explanation:

\( \text{ - 4n + 14 = - 2(n - 5)}\)

Distribute -2 through the parentheses

\( \text{↦ - 4n + 14 = - 2n + 10}\)

Move 2n to right hand side and change it's sign

\( \text{↦ \: - 4n + 2n + 14 = 10}\)

Move 14 to right hand side and change it's sign

\( \text{↦ \: - 4n + 2n = 10 - 14}\)

Combine like terms

\( \text{↦ \: - 2n = 10 - 14}\)

Remember : The negative and positive integers are always subtracted but posses the sign of bigger integer.

\( \text{↦ \: - 2n = - 4}\)

Divide both sides by -2

\( \rm{↦ \: \frac{ - 2n}{ - 2} = \frac{ - 4}{ - 2}} \)

\( \text{↦ \: n = 2}\)

The value of n is 2 .

Answer: 164.32 miles

Step-by-step explanation:

Given that:

Weekly coverage :

Miles biked to the river = 0.86 miles

Miles biked along the river back home =. 2.3 miles

Total miles biked weekly:

(0.86 + 2.3) miles = 3.16 miles weekly

Number of weeks per year = 52

Miles biked yearly : (number of weeks per year * miles biked weekly)

= 52 * 3.16 miles

= 164.32 miles

Mrs endo will bike about 164.32 miles in a year.

Use the property of determinant det(AB) = det(A)det(B) and the fact that A and A' have the same transpose to show that det(AAT) = (det(A))^2, and then use the fact that AAT is similar to A'A to conclude that they have the same characteristic polynomial. Option C is the correct answer.

Start with det(AAT). Use the formula det(AB) = (det A)(det B) to write det(AAT) = (det A)(det A). Then use the formula AAT = EI.

We can show that A and A' have the same characteristic polynomial by showing that they have the same eigenvalues.

Let λ be an eigenvalue of A with corresponding eigenvector x. Then we have:

Ax = λx

Multiplying both sides by A' on the left, we get:

A'Ax = A'λx

Using the fact that A'A = AA' = I, we can simplify this expression to:

x = λA'x

This shows that λ is also an eigenvalue of A' with corresponding eigenvector A'x. Therefore, A and A' have the same set of eigenvalues, which means that they have the same characteristic polynomial.

To prove this using determinants, we start with det(AAT). Using the property det(AB) = (det A)(det B), we can write:

det(AAT) = det(A)det(AT)

Since det(AT) = det(A) (which can be shown using the fact that det(AT) = det(A) and the property det(AB) = det(A)det(B)), we can simplify this expression to:

det(AAT) = (det A)^2

Using the fact that AAT = EI, we can write:

det(AAT) = det(EI)

Since det(EI) = 1, we have:

(det A)^2 = 1

Taking the square root of both sides, we get:

det A = ±1

This means that A and A' have the same set of eigenvalues, which implies that they have the same characteristic polynomial.

So, the correct option is C.

The train will arrive at its final destination at 2:57 P.M. in the afternoon.

The total distance of the trip is 221 miles and the train travels at an average speed of 34 miles per hour. Using the formula:

time = distance / speed

We can calculate the total time it will take for the train to complete the journey without stopping at stations:

time = 221 / 34 = 6.5 hours

However, the train stops at each of ten stations for four minutes each, so the total time spent stopping is 10 x 4 = 40 minutes, or 0.67 hours. Therefore, the total time the journey will take, including the stops, is:

total time = 6.5 + 0.67 = 7.17 hours

The train departs at 7:30 A.M., so we can add 7.17 hours to this time to find the arrival time:

7:30 A.M. + 7.17 hours = 2:57 P.M.

Therefore, the train will arrive at its final destination at 2:57 P.M. in the afternoon.

sketch of the line 4x + 3y = 11, slope (-4/3),  y-intercept of the line y = 11/3

Step 1: Convert the equation to slope-intercept form (y = mx + b) by solving for y:

3y = -4x + 11

y = (-4/3)x + 11/3

Step 2: Identify the slope and y-intercept:

From the equation in slope-intercept form, we can see that the slope (m) is -4/3 and the y-intercept (b) is 11/3.

Step 3: Plot the y-intercept:

On the y-axis, mark a point at y = 11/3 (approximately 3.67). This is the y-intercept of the line.

Step 4: Use the slope to find additional points:

Using the slope of -4/3, we can find other points on the line. The slope represents the change in y for every 1 unit change in x. So, starting from the y-intercept, we can move down 4 units and to the right 3 units to find the next point, and continue this pattern to find more points.

Step 5: Connect the points:

Once you have a few points on the line, you can connect them with a straight line. Make sure the line extends beyond the plotted points to show that it continues indefinitely.

The resulting line should have a negative slope (-4/3) and be slanting downward from left to right.

The maximum area would be a square with 4 identical sides.

36/4 = 9

Each side would be 9 feet long.

Area = 9 x 9 = 81 square feet

Answer: 81 square feet

To solve the congruence 4x ≡ 5 (mod 9), we need to find the inverse of 4 modulo 9, which we found in part (a) of exercise 5 to be 7.

Multiplying both sides of the congruence by the inverse of 4, we get:

4x * 7 ≡ 5 * 7 (mod 9)

28x ≡ 35 (mod 9)

Since 28 ≡ 1 (mod 9), we can simplify the left side of the congruence:

x ≡ 35 (mod 9)

Now we need to find the smallest non-negative integer solution for x. We can do this by repeatedly subtracting 9 from 35 until we get a number less than 9:

35 - 9 = 26
26 - 9 = 17
17 - 9 = 8

So x ≡ 8 (mod 9) is the smallest non-negative integer solution to the congruence 4x ≡ 5 (mod 9) using the inverse of 4 modulo 9 found in part (a) of exercise 5.

There are 9 shaded tenths and 18 shaded hundredths. Regroup 10 hundredths into 1 tenth to get 10 tenths and 8 hundredths. Then regroup the 10 tenths in one whole, giving you 1 whole and 8 hundredths. The product is 1.08.

Another way to get the answer is to count the total number of shaded hundredths. There are 108 hundredths. Regroup 100 of them as one whole, giving you 1 whole and 8 hundredths.

Answer: y = 2.4

Step-by-step explanation: Lets plug in 2.4 for the value y;

y = 2.4

y x 5 = 12

2.4 x 5 = 12

You can find y by dividing 12 by 5 which equals 2.4

We can plot these points on a graph with x on the horizontal axis and y on the vertical axis. Once we plot these points, we can draw a straight line passing through both points.

To calculate the slope of this line, we can use the formula:
slope = (change in y) / (change in x)
In this case, the change in y is $2000 - $1600 = $400, and the change in x is 10 - 8 = 2.
Therefore, the slope of the line is: slope = $400 / 2 = $200 per hour

This means that for every additional hour it takes the painting company to finish the house, the total cost of painting the house increases by $200. In summary, we can draw a line representing the relationship between x and y using the two points provided, and calculate the slope of the line to be $200 per hour.
