The solution is The perimeter of the sector is :30.5 cm

A perimeter is a closed path that encompasses, surrounds, or outlines either a two dimensional shape or a one-dimensional length. The perimeter of a circle or an ellipse is called its circumference. Calculating the perimeter has several practical applications.

here, we have,

Mathematically, we have the area of the sector as;

e/360 * pi * r^2

r is 8 cm

so we have

58 = e/360 * pi * 8^2

58/64 * 360/pi = e

e = 103.85

To get the perimeter,

we have length of the arc plus 2r

Length of the arc is;

e/360 * 2 * pi * r

add 2 r;

e/360 * 2 * pi * r + 2r

so we have

103.85/360 * 2 * pi * 8 + 2(8)

= 14.5 + 16

= 30.5 cm

Hence, The solution is The perimeter of the sector is :30.5 cm

Answer: The value of x from the diagram is 50 degrees.

Vertical angles are angles that meets at a point of intersection. From the given diagram 150 and 50+2x are vertical angles showing that they are equal to each other so:

50 + 2x = 150

2x = 150 - 50

2x = 100

Divide both sides by 2

2x/2 = 100/2

x = 50

Therefore the value of x from the diagram is 50 degrees.

Answer:

x = 50

Distance is defined as the amount or extent of displacement between two points. It is critical to understand that the distance between two sites does not equal the distance traveled between them. The distance traveled is the entire length of the journey traveled between two places. Distance is the length of an object's path, whereas displacement is the distance between where the thing started and where it ended up. Distance is defined as the whole length of an object's true path. The displacement of an object between two locations is the smallest straight line distance between those positions, directed from one to the other.

In a relation, each row of a table represents an ordered pair where the x-value is in the left column (also called the domain) and the y-value is in the right column (also called the range or codomain). The x-values represent the inputs to the relation, and the y-values represent the corresponding outputs.

A relation is a set of ordered pairs, where the first element of each pair comes from a set called the domain and the second element comes from a set called the range or codomain. In a table representing a relation, each row represents an ordered pair where the first element (the x-value) is from the domain and the second element (the y-value) is from the range or codomain.

For example, consider the relation R = {(1, 3), (2, 5), (3, 7)}. In a table representing R, the x column represents the first element of each ordered pair (i.e., the domain) and the y column represents the second element of each ordered pair (i.e., the range or codomain).

The first row of the table would be (1, 3), where 1 is the input (x-value) and 3 is the output (y-value) for the relation R. The second row of the table would be (2, 5), where 2 is the input (x-value) and 5 is the output (y-value) for the relation R. And so on for the rest of the rows in the table.

Therefore, each row of a table representing a relation does indeed represent an ordered pair, where the x column represents the input values and the y column represents the output values.

The difference in the variability in golf scores for players on the LPGA Tour and players on the PGA Tour can be calculated by subtracting the standard deviation for the LPGA Tour from the standard deviation for the PGA Tour.

The variability in golf scores for players on the LPGA Tour and the PGA Tour can be measured using the standard deviation. To calculate the standard deviation, the squared differences between each score and the mean score must be calculated and then averaged. Then, the square root of this average must be taken.

Formula:

Standard Deviation =√((x1–μ)2+(x2–μ)2+...+(xn–μ)2)/n

Where:

x1, x2, ..., xn are the individual observations

μ is the mean

n is the number of observations

In this case, the sample of tournament scores from LPGA events showed a standard deviation of strokes and the sample of tournament scores from the PGA Tour showed a standard deviation of strokes. The difference between the two standard deviations can then be calculated by subtracting the LPGA standard deviation from the PGA standard deviation.

Therefore, the difference in the variability in golf scores for players on the LPGA Tour and players on the PGA Tour can be calculated by subtracting the standard deviation for the LPGA Tour from the standard deviation for the PGA Tour.

It is not in control  because at least two of the  of the data points are more than 2 standard deviations from the mean are far apart.

18.3,18.4 > 18.2 Upper Control limit

14.9, > 15.4 Lower Control Limit

Step-by-step explanation:

Find the limits using μ ± 3σ  and μ ± 2σ

Using μ ± 3σ

Upper Control Limit = μ +  3σ = 16.8 + 3(0.7)= 16.8 + 2.1= 18.9

Lower Control Limit = μ - 3σ =16.8 - 3(0.7)= 16.8 - 2.1= 14.7

Using μ ± 2σ

Upper Control Limit = μ +  2σ = 16.8 + 2(0.7)= 16.8 + 1.4= 18.2

Lower Control Limit = μ - 2σ =16.8 - 2(0.7)= 16.8 - 1.4= 15.4

The data points are 17.3, 14.9, 18.3, 16.5, 16.1, 17.4, 18.4.

Rearranging these data points  14.9, 16.1, 16.5, 17.3, 17.4, 18.3,18.4.

We see from the above that it is out of control because the values jump above and below the mean.

The possible endpoints are (-3, 6) and (8, -5).

The distance between two points of a line is given as:

Distance = [tex]\sqrt{(x_2 - x_1)^2 + (y_2 - y_1)^2}[/tex]

We have,

The coordinates of the endpoints are (a, b) = [tex](x_1, y_1)[/tex] and (-3, -5) = [tex](x_2, y_x)[/tex].

The distance between the two endpoints is 11 units.

Now,

Distance = [tex]\sqrt{(x_2 - x_1)^2 + (y_2 - y_1)^2}[/tex]

11 = [tex]\sqrt{(-3 - a)^2 + (-5 - b)^2}[/tex]

Squaring both sides.

11² = (-3 - a)² + (-5 - b)²

121 = (-3 - a)² + (-5 - b)²

If we take a = -3 and b = 6

121 = (-3 + 3)² + (-5 - 6)²

121 = 0 + (-11)²

121 = 121

or

If we take a = 8 and b = -5

121 = (-3 - 8)² + (-5 + 5)²

121 = (-11)² + 0

121 = 121

Thus,

(-3, 6) and (8, -5) are the possible endpoints.

I have to flip the coin 16 times to say that I am 95% confident the coin is unfair.

This question can be answered using the binomial distribution. If we assume the coin is fair, then each flip of the coin has a 50% chance of coming up heads. We can use the binomial distribution to calculate the probability of getting heads at least 95% of the time.

For this calculation, we need to know the number of trials, n. We can use the formula: n = (1.96^2)/(p(1-p)) to calculate n for a 95% confidence level. In this case, p = 0.5, so n = 15.84. Since this is not a whole number, we can round up to 16 flips.
