Answer:

Step-by-step explanation:

The total number of marbles is 20

Question A

P(Red) = 4/20 = 1/5

P(yellow) = 9/20

P(Red then Yellow) = 1/5 * 9/20 = 9 / 100

Question B

P(B) = 6/20

P(B again) = 5/19 because you  have 1 less total plus 1 less blue.

P(B and B) = 6/20 * 5/19

P(B and B) = 30/ 380 = 3/38

Which of the following could be the graph of the line y = 3x - 2?
morpeh [17]

You didn't give a graph but I will visualize what it looks like for you.

The line is going through (0,-2) because that is the y-intercept.

The line has a slope of 3.

So, the line goes through:

(1,1)

(2,4)

(3,7)

(4,10)

(5,13)

Find the results combining these functions.
vodomira [7]
Given f(x) = x^2 + 6x + 9, g(x) = x^2 - 9:

(f+g)(x) = (x^2 + 6x+9)+(x^2-9) =2x^2+6x=2x(x+3), which is the second expression

(f-g)(x) = (x^2 + 6x+9)-(x^2-9) =6x+18=6(x+3), which is the first second expression

(fxg)(x) = (x^2+6x+9)(x^2-9) = (x^4-9x^2)+(6x^3-54x)+(9x^2-81)=x^4+6x^3-54x-81, which is the fourth expression

(f/g)(x) = (x^2+6x+9)/(x^2-9) = \frac{(x+3)^2}{(x+3)(x-3)} = \frac{x+3}{x-3}, which is the third expression
