Line AB is Perpendicular to line BC. A=(-3,2) and C=(2,7). Which of the following could be the coordinates of B? Select all that
Llana [10]

Answer:

The answer would be Choice F; (-3,7)

Step-by-step explanation:

  1. Plot the two guaranteed given points
  2. A, (-3,2) and C, (2,7)
  3. Find the point where the x and y would share and then form a right angle. This is called being Perpendicular.
  4. So, take the <em>x</em> of A, and the <em>y</em> of C and you have the coordinates of B.

Using the table for many repetitions of the experiment of tossing a coin 10 times, what is the mean number of heads in 50 repeti
PtichkaEL [24]
When there are 1000 repetitions, the mean will be 5.002.

The charts that you have list the number of total heads when you flip the coin 10 times in each trial.

Multiply the total of each by the number number of heads for that category and divide by 1000.

1 x 0
8 x 1
43 x 2
117 x 3
2017 x 4
248 x 5
203 x 6
121 x 7
45 x 8
6 x 9
1 x 10

If you add up those products and divide by 1000, you have 5.002.

Using the law of large numbers, the experiment with 1000 rolls will be the closest to the theoretical amount.

<u>Step 1: Define</u>

Point (40, 3000)

Point (60, 4000)

<u>Step 2: Find slope </u><em><u>m</u></em>

  1. Substitute:                    m=\frac{4000-3000}{60-40}
  2. Subtract:                       m=\frac{1000}{20}
  3. Divide:                          m=50
