When rolling a number cube numbered 1 to 6, how would you describe the chances of rolling a number greater than or equal to 3 ve

Andrew [12]

Answer:

A. more likely to roll a number greater than or equal to 3

Step-by-step explanation:

Take a look at the probabilities for each:

Greater than or equal to 3:

You can roll a 3, 4, 5, or 6

Less than 3:

You can roll a 1 or a 2.

To find probability, divide how many ways there are to get what you want by the number of total ways to get something at all.

For freater than or equal to 3:

You can roll a 3, 4, 5, or 6 to fulfill this, so 4 things that you want.

You could roll a 1, 2, 3, 4, 5, or 6 on this number cube, so 6 possibilities.

Divide 4 by 6, and you get 2/3.

For less than 3:

You can roll a 1 or a 2 to fulfill this, so 2 things you want.

Divide by 6 (again) total possibilities, and you get 1/3.

2/3 is more than 1/3, so the first possibility is more likely than the second.

Do anyone know how to do this?

kykrilka [37]

Answer:

1.) x=4

2.) x=14

Step-by-step explanation:

FOR #1:

1.) In order to solve the parallelogram, you must know that each opposite sides must equal...

so KL=JM and KJ=LM

2.) To solve for "x", you must substitute

$KL= 7x-2\\JM=12x-22$

so it should end up with...

$7x-2=12x-22$

3.) Solve the equation with some algebra

$7x-2=12x-22\\-5x=-20\\x=4$

FOR #2:

1.) In order for a square, rectangle, parallelogram, (or any shape with four sides), it must equal to 360°. And you just have two given angles, which equal to 180, so that means the unknown equals to 180...So in this case you should have

$(3x+5)+(9x-17)+180=360$

as your equation...

2.) Solve with algebra

$(3x+5)+(9x-17)+180=360$

$3x+5+9x-17=180\\12x-12=180\\(\frac{1}{12}) 12x=168 (\frac{1}{12})\\x=14$

<u><em>multiplied</em></u>

PLEASE I NEED ANSWER ASAP

mafiozo [28]

Answer:

42°

Step-by-step explanation:

$(7x - 2) \degree = (6x + 18) \degree\\ ..(exterior \: alternate \: \angle s) \\ 7x - 2 = 6x + 18 \\ 7x - 6x = 18 + 2 \\ x = 20 \\ \\ (7x - 2) \degree + \angle \: 1 = 180 \degree \\..(straight \: line \: \angle s) \\ (7 \times 20 - 2) \degree+ \angle \: 1 = 180 \degree \\ 138 \degree+ \angle \: 1 = 180 \degree \\ \angle \: 1 = 180 \degree - 138 \degree \\ \angle \: 1 = 42\degree$
