The probability that that arrow will land on the part labelled C after the first spin would be = 1/5.

To calculate the probability of the chosen event, the formula for probability should be used which is given as follows:

Probability = possible outcome/ sample space

Where possible outcome = 2

sample space = A,B,B,B,C,C,D,D,D,E = 10

Therefore the probability that the arrow will land on the part labelled C after the first spin = 2/10 = 1/5.

The value of secβ = (-21√10)/60.

Given that

Cosecβ = 7/3

Cotβ = -(2[tex]\sqrt{10}[/tex])/3

Since,

Cosecβ  =  1/sinβ = 7/3

⇒ sinβ = 3/7

And Cotβ = -(2[tex]\sqrt{10}[/tex])/3

⇒ cosβ/sinβ =  -(2[tex]\sqrt{10}[/tex])/3

⇒ 1/cosβ = -3/[(2[tex]\sqrt{10}[/tex])sinβ]

⇒ secβ = -21/(6√10)

Hence,

⇒ secβ = (-21√10)/60

7 groups of 2/7 is equivalent to the whole, which is represented by the number 2.

When we have 7 groups of 2/7, we are essentially multiplying the fraction 2/7 by the whole number 7. To perform this operation, we can use the following formula:

a/b × c/d = ac/bd

where a, b, c, and d are any numbers, and a/b and c/d are two fractions.

In our case, a is 2, b is 7, c is 7, and d is 1. This is because we want to multiply 2/7 by 7 to get 7 groups of 2/7. Therefore, we can substitute these values into the formula:

2/7 × 7/1 = (2 × 7) / (7 × 1) = 14/7

The result is a fraction 14/7, which can be simplified to 2. This means that 7 groups of 2/7 is equal to 2. To simplify this further, we can say that if we divide a whole into 7 equal parts, each part is 2/7. If we have 7 of these parts, we have the whole.

By using the synthetic division we have find that the quotient of x³-4x²+7 divided by x-3 is x² - x - 3, with a remainder of 4.

To use synthetic division, we first need to set up the equation in the correct format. We write the coefficients of the polynomial equation in descending order, and then we include any missing coefficients as 0. In this case, the equation x^3-4x²+7 can be written as:

1x^3 - 4x² + 0x + 7

Next, we write the linear equation in the format (x-a), where "a" is the value being divided out of the polynomial equation. In this case, a = 3, so we write the linear equation as:

(x-3)

We start by copying the first coefficient (1) from the top row to the bottom row.

We then multiply this coefficient by the value of "a" (3) and write the result (3) under the next coefficient (which is -4).

We add these two values together to get -1, which we write under the 0 coefficient.

We then repeat this process by multiplying -1 by 3 to get -3, which we write under the last coefficient (which is 7). We add these two values together to get 4.

Our synthetic division table should look like this:

3 | 1 -4 0 7 | 3 -1 -3

-----------------------------

   | 1 -1 -3 4

The bottom row of the table shows the coefficients of the quotient, which are 1, -1, and -3. These coefficients form the quotient of the division, which can be written as:

x² - x - 3

The last number in the bottom row of the table (4) is the remainder of the division. This means that our original equation x³-4x²+7, when divided by x-3, has a remainder of 4.

The  greater rate of change is 12.5, which is the rate of change of the first function.

The rate of change of a linear function is the slope of the line, which is represented by the coefficient of x in the equation y = mx + b. Therefore, the rate of change of the first function y = 12.5x + 2 is 12.5.

To find the rate of change of the second function, we can use any two points on the table and use the formula:

rate of change = (change in y) / (change in x)

Let's use the points (-3, -28.5) and (3, 37.5):

rate of change = (37.5 - (-28.5)) / (3 - (-3))

rate of change = 66 / 6

[tex]P = (d - 4r)^2 / d^2[/tex]
Here,
d = diameter of the circle
r = square side length
For the given case,
d = 4 and r = 3.
Then,
P = (4 - 4×3)² / 4²
P = (4 - 12)²/ 4²
P = 0.06

Answer:

Step-by-step explanation:

The area of the square is given as 1134 m². Let's assume that the side length of the square is "s". Then, we can write the area of the square as s² = 1134. Solving for "s", we get s = √1134. The perimeter of the square is given by P = 4s. Substituting the value of "s", we get P = 4√1134. To simplify this expression, we can factor out the perfect square factor of 36 from 1134, which gives us 1134 = 36 x 31. Therefore, P = 4√(36 x 31) = 4 x 6√31 = 24√31. Hence, the perimeter of the square is 24√31 m.

The required graph has been attached below that represents the inverse equation f(x) = 4x-1.

To graph the inverse equation f(x) = 4x - 1, we can follow these steps:

Replace f(x) with y:

y = 4x - 1

Switch the x and y variables: x = 4y - 1

Solve for y:

y = (x + 1) / 4

The graph of the original function f(x) = 4x - 1 is a line with a slope of 4 and a y-intercept of -1.

The graph of the inverse function is the reflection of this line over the line y = x, which means that the x and y coordinates of each point are swapped.

To plot points for the inverse function, we can choose some values of x and find the corresponding values of y using the equation y = (x + 1) / 4. For example:

x y

-3 -1/4

-2 0

-1 1/4

0 1/4

1 1/2

2 3/4

Therefore, the graph of the inverse equation f(x) = 4x - 1 is a line that passes through the points (-3, -1/4), (-2, 0), (-1, 1/4), (0, 1/4), (1, 1/2), (2, 3/4), and (3, 1).

The standard deviation of the given data is approximately 3.08.

To find the standard deviation of the given data (5, 6, 8, 13), we first need to find the mean (X) of the data.

Mean (X) = (5 + 6 + 8 + 13) / 4 = 32 / 4 = 8

Next, we calculate the deviations from the mean for each data point:

Deviation from the mean = Data point - Mean

For 5: 5 - 8 = -3

For 6: 6 - 8 = -2

For 8: 8 - 8 = 0

For 13: 13 - 8 = 5

Then, we square each deviation:

(-3)^2 = 9

(-2)^2 = 4

0^2 = 0

5^2 = 25

Next, we calculate the sum of the squared deviations:

Sum of squared deviations = 9 + 4 + 0 + 25 = 38

To find the variance, we divide the sum of squared deviations by the number of data points:

Variance = Sum of squared deviations / Number of data points = 38 / 4 = 9.5

Finally, we take the square root of the variance to find the standard deviation:

Standard deviation = √Variance = √9.5 ≈ 3.08

Therefore, the standard deviation of the given data is approximately 3.08.
