A bag contains 8 blue marbles 5 red marbles and 2 orange marbles , Carolina picks a marble from the bag at random and returns it to the bag and makes a second random selection . What is the probability that two blue marbles were selected

Answers

Initial total number of marbles: 8 + 5 + 2 = 15
Initial number of blue marbles: 8

First pick:
p(blue marble) = 8/15

Since the marble from the first pick is returned to the bag, the bag still contains 8 blue marbles and a total of 15 marbles.

Second pick:
p(blue marble) = 8/15

Overall:
p(blue marble followed by blue marble) =
= p(blue marble) * p(blue marble)
= 8/15 * 8/15

I really need help with this question3. Solve n^2+ n-12 by factoring. *
n= 6, n=-2
n=4, n= -3
n=-6, n= 2
n=-4, n=3

Answers

Answer:

n = -4     n=3

Step-by-step explanation:

n^2+ n-12

What 2 numbers multiply to -12 and add to 1

4*-3 = -12

4-3 =1

(n+4) (n+3) =0

Using the zero product property

n+4 = 0   n-3 =0

n = -4     n=3

Two equations are given below:m + 4n = 8
m = n − 2

What is the solution to the set of equations in the form (m, n)?

(4, 6)

(2, 4)

(0, 2)

(6, 8)

Answers

Good morning Brainiac


m=n-2

m+4n=8

We need to solve m=n-2 for m

Substitute n-2 for m in m+4n=8

m+4n=8

n-2+4n=8

5n-2=8

Add 2

5n-2+2=8+2

5n=10

Now divide both sides by 5 so we can find the value for n

5n/5=10/5

n=2

Now substitute 2 for n in m=n-2

m=n-2

m=2-2

m=0
