A bag contains 5 blue marbles, 2 black marbles, and 3 red marbles. A marble is randomly drawn from the bag.
The probibly of not drawing a black marhle is_
The probability of drawing a red marble is_

Question 1:  4/5 or %80

Question 2:  7/10 or %70

Step-by-step explanation:

Step 1:  Find the total amount of marbles

5 + 2 + 3

10

Step 2:  Find the probability of not drawing a black marble

Add the total amount of marbles that are not black

5 + 3

8

Now find the probability:  

8/10

4/5 or %80

 4/5 or %80

Step 3:  Find the probability of not drawing a red marble

Add the total amount of marbles that are not red

5 + 2

7

Now find the probability:

7/10 or %70

 7/10 or %70

555.99.

step-by-step explanation:

hope this

step-by-step explanation:

let

we know that

the y-intercept is the y-coordinate of the point when the value of x is equal to zero

so

the y-coordinate of the point a is the y-intercept

the answer part a) is

the value of y-intercept is

part b) find the slope m

we know that

the value of the slope is equal to

substitute the values

therefore

the answer part b) is

the value of the slope is equal to

the general answer is

the slope is

the value of y-intercept is
