The mean increases by two.
15+23+24+26+27+35 = 140
140/6 = 23.3
23+24+26+27 = 100
100/4 = 25
The mean roughly increases by 2.
Answer:
4,000,000
Step-by-step explanation:
millions, thousands, hundreds
5+10=15
or 1+1+1+1+1+1+1+1+1+1+1+1+1+1+1
The first step is to write this equation into general form. The
general form of an equation is:
ax^2 + bx + c = 0
To make this equation to general form, you have to simplify
the equation first.
2/3(x-4) (x+5) = 1
2/3 (x^2 + 5x – 4x – 20) = 1
2/3(x^2 + x -20) = 1
2/3x^2 + 2/3x – 40/3 = 1
2/3x^2 + 2/3x – 40/3 – 1 = 0
2/3x^2 +2/3x – 43/3 = 0
Therefore, a = 2/3 ; b = 2/3 ; c = -43/3
