For which set of data are the median and mode the same number?

4, 5, 7, 7, 8, 10
3, 5, 6, 8, 8, 9
5, 5, 6, 8, 9, 10
4, 5, 7, 8, 9, 9

Median is middle value, mode is number that appears the most.

4 +5 +7+7+8+10 =  median = 7, mode = 7

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
