Write an equation in point-slope form for the line through the given point with the given slope.
Lilit [14]

The correct answer is D) y + 1 = 4/3(x - 9)

In order to find this, simply take the point and the slope and plug into the base form of point-slope form.

y - y1 = m(x - x1)

Use the slope for m and the point for (x1, y1)

y + 1 = 4/3(x - 9)

When constructing a perpendicular bisector why must the compass opening be greater than 1/2.
muminat

It is critical to open a compass with over half the way in order for the arcs formed to meet for perpendicular bisector.

<h3>What is perpendicular bisector?</h3>

A perpendicular bisector would be a line that cuts a line segment in half and forms a 90-degree angle at the intersection point. In other words, a perpendicular bisector separates a line segment now at midpoint, forming a 90-degree angle.

Now, consider an example;

When you wish to build a perpendicular line on a line segment, like line AB, you do the following;

  1. Set the compass on a radius more than half the length of the line AB.
  2. Using A as your center, draw an arc above and below line AB.
  3. With the same radius and B as our center, draw additional arcs on top or below line AB to join a first arcs on the both side of the line.
  4. Join the two arc intersections to cut line AB at M.

A line AB appears to be bisected perpendicularly as a result. The arcs would not have met if the compass is opened less than half way down line AB.

Looking at the means of these samples, which value is most likely to be the mean of the population from which the samples were t
eduard

Answer:

We are given the below data:

Sample Number              Sample Mean

1                                                 11.8

2                                                 12.5

3                                                 15.1

4                                                 14.3

5                                                 13.0  

6                                                 12.9

7                                                 10.2  

8                                                 11.5

9                                                 12.9

10                                                15.4

Now the most likely mean of the population can be found by finding the mean of given sample means. It is given below:

Mean = \frac{11.8+12.5+15.1+14.3+13.0+12.9+10.2+11.5+12.9+15.4}{10}

               =12.96

Therefore, the most likely mean of the population from which the samples were taken is 12.96
