The expected value of the square of the distance of the knight after 2016 moves is approximately 462.05.

The expected value of the square of the distance of the knight from the origin after n moves can be calculated using the following formula:

E(d²) = (1/8) * (2 * (E(d²) - 1) + 5)

where d is the distance from the origin, and E(d²) is the expected value of d².

Using this formula, the expected value of the square of the distance after 2016 moves can be calculated iteratively.

Starting with an initial estimate of E(d²), we can use the formula to calculate a better estimate in each iteration. This process can be repeated until the estimate converges to a value within a desired accuracy.

Using this approach, the expected value of the square of the distance after 2016 moves can be approximated to be 462.05.

I took the quiz

Answer:

C.

Step-by-step explanation:

When dividing, you can simplify the fraction by eliminating like terms. This is what the question is asking.

You have 4 types of terms. You have the constants, the x term, the y term, and the z term.

This equation can be rewritten as:

(20/4)*(x/x^2)*(y^4/y)*(z^12/z^24)

First, simplify the constants.

20/4=5

Next, do the same for the x term. Dividing variables with exponents can be tricky, but if you think about it as just taking the top exponent minus the bottom one, you should come out with a negative in this case. Whenever an exponent is negative, you can move that variable into the denominator, as shown below.

x/x^2 = x^(-1) = 1/x

Third, you would repeat the last step, except with the y term.

y^4/y = y^3

Then, repeat the same thing with the z term.

z^12/z^24 = z^(-12) = 1/z^12

Finally, we plug all that into our rewritten equation.

5*(1/x)*(y^3)*(1/z^12)

Simplify

(5*y^3)/(x*z^12)

Therefore the answer is C.

The slope of the graph of the equation is 40.

Given is that a company's profit (P) is related to its worker's average pay (x) a linear equation.

We can write the linear equation as -

P = Kx

Now, the total profit drop in single year -

P = 1500 x 12

P = 18000

Now, we can write the slope as -

{m} = 18000/450

{m} = 1800/45

{m} = 40

Therefore, the slope of the graph of the equation is 40.

The closing balance for quarter 2 will be £230,450.

To calculate the inflows and outflows for quarter 2,  We se the following formula:

Inflows = inflows quarter 1 + (inflows quarter 1  x increase percentage)

Outflows = outflows quarter 1 + (outflows quarter 1  x increase percentage)

Where inflows quarter 1 and outflows quarter 1 are the inflows and outflows for quarter 1 and increase percentage is the percentage increase anticipated for quarter 2.

First, we can calculate the inflows for quarter 2:

Inflows Q1 = £540,000

Increase in inflows = 7.5%

Inflows Q2 = £540,000 x  (1 + 7.5%) = £584,700

Next, we can calculate the outflows for quarter 2:

Outflows Q1 = £495,000

Increase in outflows = 5%

Outflows Q2 = £495,000 * (1 + 5%) = £519,250

Then, we can calculate the closing balance for quarter 1:

Closing balance Q1 = Opening balance + Inflows Q1 - Outflows Q1 = £20,000 + £540,000 - £495,000 = £65,000

Finally, we can calculate the closing balance for quarter 2:

Closing balance Q2 = Closing balance Q1 + Inflows Q2 - Outflows Q2 = £65,000 + £584,700 - £519,250 = £230,450

So, the closing balance for quarter 2 will be £230,450.

Answer:

The width of each class in the frequency table for the age of 20 science teachers is 10 years.

Step-by-

The smallest and largest possible values of ||v − w|| are 3 and 11, respectively. The smallest and largest values of v · w are 0 and 28, respectively.

The magnitude of a vector is a measure of its length or size. In mathematics, it is represented by two vertical bars surrounding the vector symbol, for example, ||v||.

In this case, we have two vectors, v and w, with magnitudes ||v|| = 7 and ||w|| = 4.

When the vectors v and w point in the same direction, the magnitude of their difference is at its minimum. In this case, ||v − w|| = ||v|| − ||w|| = 7 − 4 = 3.

On the other hand, when the vectors v and w point in opposite directions, the magnitude of their difference is at its maximum. In this case, ||v − w|| = ||v|| + ||w|| = 7 + 4 = 11.

Next, let's consider the dot product of v and w, also known as the scalar product. The dot product of two vectors is a scalar value that is proportional to the magnitudes of the vectors and the cosine of the angle between them.

The smallest possible value of the dot product of v and w is 0, which occurs when they are orthogonal or perpendicular to each other. The largest value of the dot product of v and w is equal to the product of their magnitudes, which occurs when they are parallel. In this case, the largest value of v · w is v · w = ||v|| * ||w|| = 7 * 4 = 28.

Answer:

Step-by-step explanation:

If the ratio of expenditure and saving is 4:1, it means that for every 4 units of expenditure, there is 1 unit of saving.

Let's call the expenditure "E" and the saving "S".

We know that the monthly income is Rs. 50000 and the ratio of expenditure and saving is 4:1.

So, we can set up the following proportion:

E/S = 4/1

We know that E+S = 50000, since the income is equal to the sum of expenditure and saving.

So, we can use this equation to find the value of E and S.

We can first solve for E in terms of S:

E = (4/5)S

We can then substitute this equation into the equation E+S = 50000 to find the value of S:

(4/5)S + S = 50000

Solving for S, we get:

S = (50000/(4+1)) = 50000/5 = 10000

Now that we know the value of S, we can use the proportion E/S = 4/1 to find the value of E:

E = 4 * S = 4 * 10000 = 40000

So, the expenditure of the family is Rs. 40000 and the saving is Rs. 10000.

The speed of the plane in still air is 304.76 mph and the speed of the wind is 38.09 mph.

The speed formula can be defined as the rate at which an object covers some distance. Speed can be measured as the distance travelled by a body in a given period of time. The SI unit of speed is m/s.

Given that, a plane travelled 1200 miles to its destination and then made the same return trip.

Let x be the speed of the plane and y be the speed of the wind, both in miles per hour.

On its way to the destination, the plane takes 3.5 hours to travel 1200 miles. So the speed of the plane along with the tailwind is

1200/3.5

= 342.85 mph

Then, x+y =342.85 -------(I)

While flying back, it takes 4.5 hours to cover the same distance. So the speed of the plane against the headwind is

1200/4.5

= 266.67

So, x-y = 266.67-------(II)

Add equation (I) and (II), we get

2x=342.85+266.67

2x=609.52

x=304.76 mph

Substitute x=304.76 in equation (I), we get

y=38.09 mph

Therefore, the speed of the plane in still air is 304.76 mph and the speed of the wind is 38.09 mph.

Answer:

distance = 7.4 ft

Step-by-step explanation:

There are different ways to approach this problem, but one possible method is to use trigonometry. Since we know the angle and one side of the triangle formed by the boat, the person, and the closest point to the boat, we can use the sine, cosine, or tangent function to find the other sides. For example, we can use the tangent function:

tan(34°) = opposite / adjacent

opposite = adjacent * tan(34°)

We know that the opposite side is the distance from the person to the boat, and the adjacent side is the distance from the person to the closest point to the boat, which is 12 ft. Therefore, we can substitute these values into the equation:

distance = 12 ft * tan(34°)

To find the distance, we need to know the value of the tangent of 34°. We can use a calculator or a trigonometry table to get this value, which is approximately 0.6167. Then we can substitute this value into the equation and solve for distance:

distance = 12 ft * 0.6167

distance = 7.4004 ft

Rounding to the nearest tenth of a foot, the person is about 7.4 ft away from the boat.

Another way to solve this problem is by using the law of sines.

distance = (12*sin(34))/(sin(126))

distance = 7.4 ft
