find the length of the line segment with end points (7,2) and (-4,2) explain how you arrived at your solution

Inga [223]

Answer:

<h2>11 units</h2>

Step-by-step explanation:

Method 1:

The formula of a distance between two points:

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

We have the points (7, 2) and (-4, 2). Substitute:

$d=\sqrt{(2-2)^2+(-4-7)^2}=\sqrt{0^2+(-11)^2}=\sqrt{11^2}=11$

Method 2:

Look at the picture. Mark points in the coordinate system.

Read the length of the segment.

2. Carol wants to find how many people in her town own a dog as a pet. She decides to survey

kaheart [24]

This is not a random sample since she is outside of a pet store and the probability of people owning a dog coming out of that store is very very high. If she went around the neighborhood and knocked on people’s door and asked if they had a dog or not would be random sample.
