A bag contains: 5 red marbles
6 blue marbles
3 green marbles
4 black marbles
2 yellow markers
A marble will be drawn from the bag and replaced 100 times. What is a reasonable prediction for the number of times a green or black marble
will be drawn?
O 14
O 65
O 7
O 35

35 is the answer

Step-by-step explanation:

5+6+3+4+2=20

3+4=7

7/20=x/100

20·5=100

7·7=35

35/100

the polynomial is a perfect square trinomial of the form a^2-2ab+b^2:

option a. true

step-by-step explanation:

9x^2-12x+4

comparing with the form a^2-2ab+b^2

1.) a^2=9x^2

solving for a: square root both sides of the equation:

sqrt(a^2)=sqrt(9x^2)

a=sqrt(9) sqrt(x^2)

a=3x

2.) b^2=4

solving for b: square root both sides of the equation:

sqrt(b^2)=sqrt(4)

b=2

to be a perfet square trinomial 2ab must be equal to 12x. let's check:

2ab = 2 (3x) (2)

2ab = 12x

correct
