If there are 100 students in your class and everybody flips a coin five times, how many people are likely to get five heads in a row? The question is how many people are likely to get 5 heads in a row if 100 students flip the coin 5 times. I know that it's 1/2 probability and 5 times will give 1/32 chance, I'm looking for how many people are likely to get 5 heads in a row with 100 students.

Thanks in advance.

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

the one where 1 and 2 are directly across from each other.
