For number 1, the median is 8
For number 2, the mode is C.100
And for number 3, the mean is D.410
In scientific notation it would just be 3.06 x 0, it is the same thing as the regular notation.
The answer should be 0.5x^4+12.5
120000 is your answer because if you go to a calculator and type in 24000 divided by 20% then it will give you 120000.
11x -7y= -14 (1)
x -2y= -4 (2)
Multiply (2) by 11, we have:
11x -22y= -44 (3)
Take (1)-(3), we have:
(11x-11x)+ (-7y-(-22y))= -14-(-44)
⇒ -7y+22y= -14+44
⇒ 15y= 30
⇒ y= 30/15
⇒ y= 2
x= -4+ 2y= -4+ 2*2= 0
The final answer is x=0, y=2~
