Plss help! Calculate the mean, median, and mode of the following set of data. Round to the nearest tenth.
2, 3, 1, 4, 4, 3, 4, 12, 15, 1,4
mean = 4.4, median = 4, mode = 8
mean = 4.8, median = 4, mode = 4
mean = 4.4, median = 4, mode = 4

Step-by-step explanation:

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

a 90 degree rotation across the the origin followed by a reflection across the x-axis.
