The answer is 8
To work out you do :
6+12+7+5+11+6+9 which equals 56
Then you count how many numbers there are so that’s 7 and then you do 56 divided by 7(so the total of the numbers added and the amount of numbers there are) and then you get your answer :)
√(15+x) = 2x+3
take sqr for both side
15x+10=(2x+3)^2
15x+10=4x^2+9+2*2x*3
15x+10=4x^2+9+12x
4x^2-3x--1=0
solve it u will x=1,-1/4
(3p - 7)(3p + 7) =
(3p × 3p) + (3p × 7) + (-7 × 3p) + (-7 × 7) =
9p^2 + 21p - 21p - 49
= 9p^2 - 49
Therefore, answer would be D.
I believe Maine Coone would weigh more because its mean is 6.2 and that is a greater amount than 3.
