Answer:
Option C, the graph does not flip because 2 is positive
<span>3 is 1.0 below the mean. That is 1.0 / 0.9, or 1.1111... standard deviations below the mean.
So look up z < -1.11 on your graphing calculator.
It should be around 0.1335 or 13.35%</span>
Answer:
x ≈ -7.73 , - 4.27
Step-by-step explanation:
x² + 12x + 33 = 0 ( subtract 33 from both sides )
x² + 12x = - 33
To complete the square
add ( half the coefficient of the x- term )² to both sides
x² + 2(6)x + 36 = - 33 + 36
(x + 6)² = 3 ← take square root of both sides )
x + 6 = ± ( subtract 6 from both sides )
x = - 6 ±
Then
x = - 6 - ≈ - 7.73 ( to the nearest hundredth )
x = - 6 + ≈ - 4.27 ( to the nearest hundredth )

-2w (w + 8)
Assuming that it is a polynomial from which you must find the roots, we must first rewrite it:
-2w (w + 8) = 0
The roots are then:
w1 = 0
w2 = -8
Assuming you only have to rewrite the expression, the answer is:
-2w ^ 2 -16w
Answer:
w1 = 0
w2 = -8
-2w ^ 2 -16w
