Answer: $\frac{6}{2}$

Step-by-step explanation:

1. Use this $\frac{f(b)-f(a)}{b-a}$ to find the average rate of change

2. Average rate of change = $\frac{f(8)-f(6)}{8-6}$

3. $f(8) = - 4$ and $f(6) = -10$ (To find these you will need to look at the points on the graph. So the points (8,-4) and (6,-10))

4. Replace -4 to f(8) and -10 to f(6)

5. So it will look like $\frac{-4-(-10)}{8-6}$

6. Solve $\frac{6}{2}$

Use any model to solve the story problem. A single board is 1/12 meter thick. How many boards are there in a stack of boards tha

Colt1911 [192]

If a single board measures 1/12 of a meter then it would take 12 boards to make a meter. Since, the stack is 2 meters high. You would multiply 12 and 2 to get 24. There is 24 boards in the stack.

Using the concept of probability and the arrangements formula, there is a

0.002 = 0.2% probability that the first 8 people in line are teachers.

----------------------------------

A probability is the number of desired outcomes divided by the number of total outcomes.
The order in which they are positioned is important, and all people will be positioned, and thus, the arrangements formula is used to find the number of outcomes.

The number of possible arrangements from a set of n elements is given by:

$A_n = n!$

----------------------------------

The desired outcomes are:

First 8 people are teachers, in 8! possible ways.
Last 4 are students, in 4! possible ways.

Thus, $D = 8! \times 4!$

----------------------------------

For the total outcomes, number of arrangements of 12 people, thus:

$T = 12!$

The probability is:

$p = \frac{D}{T} = \frac{8! \times 4!}{12!} = 0.002$

0.002 = 0.2% probability that the first 8 people in line are teachers.

A farmer wants to use 200 feet of fencing for a chicken pen he wants the width of the pen to be 20 feet what is the length of th

Dominik [7]

The length should be 80 feet.
This is because the width is 20 since there are two sides for the width in pen, we have to add 20+20. This would equal 40. Then we need to subtract 40 from 200. 200-40 would be 160. Then since there are two sides for the length, we need to split that in half. 160÷2 would be 80. To double check, you can do 80+80, and that would still be 160. So the length of one side would be 80. But of course, this whole thing would only be right if the pen has four sides(but since I have seen many chicken pens, there were all rectangular)

12 and 35 Pythagorean theorem

Natali [406]

Answer:

Hypotenuse = 37

Step-by-step explanation:

Let the base is 12 and height is 35.

We can use Pythagorean theorem to find the third side (hypotenuse or the longest side). The Pythagoras theorem can be given by :

$H^2=b^2+h^2\\\\H^2=12^2+35^2\\\\H^2=1369\\\\H=\sqrt{1369} \\\\H=37$
