Caley has a bag that contains 9 blue marbles and 13 yellow marbles. She selects a marble at random, and then, without replacing the first one, selects another marble at random. What is the probability that Caley selects a blue marble and then a yellow marble? Round your answer to the nearest percent. P(blue and yellow) ≈ %

Answers

Answer 1
Answer: The answer would be 24%.

You need to multiply the probabilities of each of those circumstances occurring separately (9/22 for choosing a blue one and 13/22 for choosing a yellow one) in  order to find the probability of them happening in a row.

9/22 * 13/22 * 100% ~ 24%

How do you graph y-2x=2

Answers

turn it into y=mx+b form so it is y=2x+2 the b=2 so y intercept is (0,2) and the slope is 2, do a rise of two and a run of 1 and then connect the dots

To determine if an ordered pair is a solution to a system of linear equations in two variables, __________.A.
substitute the coordinates of the ordered pair into either equation to see if it produces a true statement
B.
substitute the coordinates of the ordered pair in both equations to see if it produces a true statement for each
C.
substitute the coordinates of the ordered pair in the first equation to see if it produces a true statement
D.
substitute the coordinates of the ordered pair in the second equation to see if it produces a true statement

Answers

Answer:

B

Step-by-step explanation:

When an ordered pair is a solution to a system of equations in two variables, it must mean that when you plug in the ordered pair into both equations, it must come out true (this is literally the definition of a solution to a system of equation). Technically, A is also facts, but B is a "more inclusive" facts so that's your answer. Hope this helps! :)

How do I reduce a fraction to its lowest term?

Answers

Step-by-step explanation:

Well, to reduce a fraction to lowest terms, divide the numerator and denominator by their Greatest Common Factor. This is also called simplifying the fraction.

To find the Greatest Common Factor, you must:

1. List the prime factors of each number.

2. Multiply those factors both numbers have in common. If there are no common prime factors, the GCF is 1.
