12x² - 11x = 11
Can be rearranged to
12x² - 11x - 11 = 0
Where
a = 12
b = -11
c = -11
To find the discriminant, we do
b² - 4ac
Therefore, the discriminant is 649, which is greater than 0
Therefore the equation has two real irrational solutions.
.1 would be your answer. it has to add up to 1 and 1-.9=.1
The deviation from 80 of about 16 is normal.
So the lowest is usually 80 - 16 = 64 and the highest is 80 + 16 = 96
But now we have a "deviation" that is 2 standard deviations above the mean score.
So 80 + 16 + 16 = 112 is this score.
Hope this helps.
