Answer:

5

Step-by-step explanation:

Segments are named by their endpoints. Therefore, segment PQ will have endpoints P and Q. The length of the segment is equal to the distance between these points.

To find the distance between P and Q given their coordinates, use the distance formula:

d=\sqrt{(x_2-x_1)^2+(y_2-y_1)^2}

Let:

P(-2, 7)\implies (x_1, y_1),\\Q(1, 3)\implies (x_2, y_2)

The distance between these points is equal to:

d=\sqrt{(1-(-2))^2+(3-7)^2},\\d=\sqrt{3^2+(-4)^2},\\d=\sqrt{9+16},\\d=\sqrt{25},\\d=\boxed{5}

Answer:

5

Step-by-step explanation:

This problem gives one the following points on a line: (P(-2,7)), and (Q(1,3)). The problem asks one to find the distance between the two points. The formula to find the distance between two points on a coordinate point is the following,

D=\sqrt{(x_2-x_1)^2+(y_2-y_1)^2}

Substitute the given values in and solve for the distance;

D=\sqrt{(-2)-(1))^2+((7)-(3))^2}

Simplify,

D=\sqrt{(-2)-(1))^2+((7)-(3))^2}\\\\D=\sqrt{(-3)^2+(4)^2}\\\\D=\sqrt{9+16}\\\\D=\sqrt{25}\\\\D = 5

LekaFEV [45]

Answer: F. Parameter, because the data set of all 2000 students in a high school is a population.

Step-by-step explanation:

Parameters is a variable or measure that is calculated from the entire population of data while a statistic is done from a sample of the data.

The question notes that the poll was done on <u>all 2,000</u> students in a high school. This means that the poll is a Parameter because it was done on the entire population of the high school.

Answer:

(4,2)

Step-by-step explanation:

Just by looking at the graph, you can see that they intersect at (4,2). But just to check:

x - 2 = -0.5x + 4

1.5x = 6

x = 4

y = 4 - 2 = 2

A water skiing jump is 4.6m long. It rises 1.1m. What

The inclination to the nearest tenth of a degree exists 0.24146

<h3>What is the inclination to the nearest tenth of a degree?</h3>

The given scenario includes a right-angled triangle where the length of the ramp exists hypotenuse and the rise of ramp exists the perpendicular.

Given: H = 4.6 m and P = 1.1 m

We have to use the trigonometric ratios to find the angle. The ratio that has to be used should involve both perpendicular and hypotenuse

Let x be the angle then

sin x = P/H

sin x = 1.1/4.6

sin x = 0.23913

$$sin^{-1} x = 0.24146

The inclination to the nearest tenth of a degree exists 0.24146
