Answer:
x-8<-15
Step-by-step explanation:
(xy)' + (2x)' + (3x^2)' = (4)'
y + xy' + 2 + 6x = 0
xy' = -y -2 -6x
y' = [-y -2 -6x] / x
Now solve y from the original equation and substitue
xy + 2x + 3x^2 = 4 => y = [-2x - 3x^2 + 4] / x
y' = [(-2x - 3x^2 +4) / x - 2 - 6x ] / x
y' = [-2x - 3x^2 + 4 -2x -6x^2 ] x^2 = [ -4x - 9x^2 + 4] / x^2 =
= [-9x^2 - 4x + 4] / x^2
5. We add all the freshman, 92 + 86 = 178.
6. We add all the sophomores surveyed, 116 + 52 = 168,
7. We add the numbers under the "yes" category, 92 + 116, which is 208.
8. We add the numbers under the "no" category, 86 + 52, which is 138.
11. A marginal frequency is the total of freshman, 222, and the total sophomores are 192. The marginal frequency of freshman are greater than that of the sophomores.
(there is no #9, #10, or a table for #12)
F(1) = -2 because the x intercept is 1 and the y intercept is -2
Answer:
Both Anoki and David are correct. Both expressions are equivalent to the difference between the measurements and are always positive because they give the absolute value of the difference.
