Answer:

4.9%

Step-by-step explanation:

There are a total of 20 marbles.

The probability that the first marble is green is 8/20.

The probability that the second marble is green is 7/19.

The probability that the third marble is green is 6/18.

The total probability is:

P = (8/20) (7/19) (6/18)

P ≈ 0.049

The probability is 4.9%.

What is the slope of a line that contains the points (-2,2) and (3,4)
vlada-n [284]

Answer:

The slope of the line that passes through these two points is 2/5

hope this helps ;)

Step-by-step explanation:

to find the slope (m) use the slope formula

m= y2-y1 / x2-x1

*plug in your points*

m= 4-2 / 3- -2    note here the <u>3- -2</u> changes to <u>3+2</u>

solve for m

m= 2/ 5  

slope= 2/5

It takes two apples to make an apple pie. If a chef bought nine apples, the last pie
defon

Hey!

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

If a chef bought 9 apples and each pie takes 2 apples then all we have to do is divide.

9 / 2 = 4.5

4 full pies can be made with 9 apples.

4 x 2 = 8 (apples were used to make 4 pies.)

9 - 8 = 1 (apple remaining)

If one pie needs 2 apples, subtract.

2 - 1 = 1 (pies the chef needs to make the last one)

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

Answer: The last pie would need 1 more apple.

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

Hope This Helped! Good Luck!
