The correct answer for the exercise shown above is the first option and the las option, which are:

 <span>y = 3x + 20
 3x - y = -20
</span>
 The explanation is shown below:

 1. You have the folllowing expression given in the problem above:

 y-2=3(x+6)

 2. If you solve it for y, you have:

 y-2=3x+18
 y=3x+18+2
 y=3x+20

 3. And if you move the variables to the left member, you have:

 3x-y=-20

 Therefore, as you can see, the correct answer are the options mentioned above.

What is p (of four sevens in a row in a two dice toss)?
ivolga24 [154]

Answer:

P = 0.0008   (non rounded answer is 0.000771605)

Step-by-step explanation:

You first need to determine how many different ways you can roll a 7 using 2 dice.  You options are...

First Die    Second Die

  1                     6

  2                    5

  3                    4

  4                    3

  5                    2

  6                    1

There are six different ways to roll a 7.  If you do the same for all possible numbers, you will see that there are 36 total options when rolling two dice.  The first die has six options, and the second die also has 6 options.  6x6 = 36.  (This is the fundamental counting principal you have have leared in statistics)

So the chances of rolling a 7 one time with two dice is 1/6.  Since repeated rolling of dice is an independent event (any roll has no effect on the next roll), you multiply the probabilities of each event.

So the probability of rolling a 7 four times in a row is

(1/6)(1/6)(1/6)(1/6), which simplifies to 1/6^4, or 1/1296,

Probability is written in decimal form, and usually rounded to 4 decimal places.

1/1296 =   0.000771605,  or  0.0008 rounded to 4 decimals

The diameter of your circle is 26 m, just multiply your radius by 2

The circumference of the circle is about 81.68


The equation to finding the area is

pi x r x 2

3.14 times 13 times 2

The equation to finding the diameter

r x 2

radius times 2

The equation for finding circumference

pi x d

3.14 times 26

Let me know if im wrong, otherwise I want brainliest, PLEASE!!
