There are a total of 8 balls 

The probability of drawing a white ball is 4/8 on the first draw.
If you replace the ball then the probability will still be 4/8 for a white ball, since these events are independent of each other you multiply 4/8 x 4/8 = 16/64 or 1/4 then the probability of drawing at least 1 red ball with replacement is 1 - 1/4 = 3/4

Now without replacement:
the probability of drawing a white ball is 4/8 since you don't replace the ball then the probability of drawing a white ball the second time is 3/7 again multiply these two probabilities: 4/8 x 3/7 = 12/56 the the probability of drawing at least 1 red ball is 1- 12/56 = 44/56 or 11/14

The graph shows the system y=2x+1 y=2x^2+1 Which ordered pairs are solutions of the system?
zhenek [66]
Hey!


To solve this problem, we would really have to graph both equations.

<em>OPEN THE FIRST IMAGE</em>

The first image I provided was the image of this equation graphed: <span>y=2x+1

<em>OPEN THE SECOND IMAGE</em>

The second image I provided was the image of this equation graphed: </span><span>y=2x^2+1


<em>PLEASE DO NOT LOOK AT THE THIRD IMAGE YET!</em>


The first image has two points. One at ( -0.5, 0 ) and the other at ( 0, 1 ).

The second image has only one point, which is at ( 0, 1 ).

<em>OPEN THE THIRD IMAGE</em>

Now, when both are combined we see that they intersect at two points, which are ( 0, 1 ) and ( 1, 3 ).

So, our answer is...

<em>The ordered pairs that are the solution to the system are</em>  </span><span>( 0,1 ) and ( 1,3 ).

Hope this helped!
