This is what I got.
You have to find the common denominator in order to minus them:)
Answer:
the last one
Step-by-step explanation:
The probability you will draw a blue marble on your first draw and then draw a blue marble on your second draw is 0.063.
<h3>What is probability?</h3>
It is defined as the ratio of the number of favorable outcomes to the total number of outcomes, in other words, the probability is the number that shows the happening of the event.
Total marbles = 20
Number of blue marbles = 5
P(blue) = 5/20
P(blue∩blue) = P(blue)×P(blue)
= (5/20)(5/20)
= 25/400
= 1/16
= 0.0625 ≈ 0.063
Thus, the probability you will draw a blue marble on your first draw and then draw a blue marble on your second draw is 0.063.

Answer:
y = 4
Step-by-step explanation:
equate these two equations, obtaining 2x+2 = x^2+3. Solving this for x, we get:
x^2 - 2x - 2 + 3 = 0, or x^2 - 2x + 1 = 0. This is equivalent to (x - 1)^2 = 0. There's a double root here: x = 1 and x = 1.
Since Y=2x+2, y = 2(1) + 2, or y = 4, when x = 1.
The y-coordinate of the solution is y = 4.
The more plot point the better but you must have at least three points, a labeled X-axis and Y-axis, and a table for the data to be organized into.
