Twenty-five randomly selected students were asked the number of movies they watched the previous week. the results are as follows: # of movies frequency 0 5 1 9 2 6 3 4 4 1 round your answers to two decimal places. the mean is: 5 the median is: 6 the sample standard deviation is: 2.92 the first quartile is: 2.5 the third quartile is: 7.5 what percent of the respondents watched at least 3 movies the previous week? % 56% of all respondents watched fewer than how many movies the previous week?

no solution.

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
