Answer:
x=1/3y - 2
Step-by-step explanation:
96 - 4.5y - 3.2y = 5.6y + 42.80
96 - 7.7y = 5.6y + 42.80
96 = 5.6y + 42.80 + 7.7y
96 = 13.3y + 42.80
96 - 42.80 = 13.3y
53.2 = 13.3y
4 = y
hope that helps, God bless!
Answer:
X=4,4
Step-by-step explanation:
2 x^2 – 16 x + 32 = 0
2(x^2-8x+16)=0
X^2-(4+4)X+16=0
x^2-4x-4x+16=0
x(x-4)-4(x-4)=0
(x-4)(x-4)=0
X=4,4
So the solution is X=4,4
In order to find the standard deviation you must find the mean, then subtract the mean to the square, then find the mean of the square, then take the square root of that and you have you're answer.
Hope this helps!
Good luck.
