If you want the X intercept put zero on the y. If you want to find Y intercept put zero on the X

1.5x-0=10.2

5x=10.2

X=2.04

2.9(0)+3y=-18.3

3y=-18.3

Y=-6.1

3. 6(0)-4y=-12

-4y=-12

Y=3

6x-4(0)= -12

6x=-12

X=-2

To find the x-intercept, substitute in 0 for y and solve for x. To find the y-intercept, substitute in 0 for and solve for y. x-intercept(s): (2,0) y-intercept(s): (0,−10)

A Fair coin is tossed and a marble is chosen from the bag whose contents are shown below. what is the probability of the coin La

Vera_Pavlovna [14]

Answer:

P(Coin landing heads and blue marble is randomly selected) = 3/20.

Step-by-step explanation:

In this question, two events simultaneously take place. First, all the probabilities have to be identified. It is mentioned that the coin is a fair coin, therefore the probabilities of all the outcomes associated with the coin tossing will be equal. Therefore:

P(Coin landing heads) = 1/2.

P(Coin landing tails) = 1/2.

There are a total of 3 blue + 4 green + 3 red = 10 marbles in the bag. Therefore:

P(Selected marble is blue) = 3/10.

P(Selected marble is green) = 4/10.

P(Selected marble is red) = 3/10.

Assuming that both the events are independent, the probabilities of both the events can safely be multiplied. Therefore:

P(Coin landing heads and blue marble is randomly selected) = 1/2 * 3*10 = 3/20.

Therefore, the answer is 3/20!!!
