Answer:
8
Step-by-step explanation:
The constant of variation is the constant in the equation: 8.
___
The equation can be rewritten to be
y = 8/x
Compared to the generic equation for inverse variation, ...
y = k/x
we see that the constant of variation (k) is the constant in the given equation, 8.
Answer:
Vertical.
Step-by-step explanation:
It is vertical because 4 + 4 (adding both X-axis, totalling 8) is smaller than 9 + 2 (adding both Y-axis, totalling 11), so the Y-axis, which is vertical, is bigger.
Answer: -4
Step-by-step:
-x^2+5x-1 x _ = 4x^2-20x+4
4x^2-20x+4 / -x^2+5x-1
In the blank the answer would be -4 which is the monomial.
A. X ~ N(66, 6.25)
b.
Using a standard normal probability table to find probability values for the z-scores, we get:
P(65 < X < 69) = 0.1554 + 0.3849 = 0.5403
c. z= 0.524 and -0.524
1.31 = X - 66
X = 67.31
When z = -0.524, X = 64.69.
P(64.69 < X < 67.31) = 0.4
