Answer:
See attached diagram
Step-by-step explanation:
You are given the equation of hyperbola

From this equation,
- the center of hyperbola is at point (1,-3);
- the real semi-axes

- the imaginary semi-axes

Draw two parallel lines x=1 and y=-3 (they intersect at the center of hyperbola), then on horizontal line match two hyperbola's vertices (7 units to the left and 7 units to the right from the center). Then draw two branches of hyperbola (one in negative direction and one in positive direction).

Answer:
Step-by-step explanation:
A. In each drawing, the odds of choosing green is 7 / (7 + 13 + 9) = 7/29
with replacement, the odds in each drawing are the same
7/29•7/29•7/29 = 7³/39³ = 343 / 24,389
B.
Odds of drawing all non black balls is the sum of odds of drawing the following possible patterns
ggg + ggr + grg + rgg + rrg + rgr + grr + rrr
(7•6•5 + 7•6•9 + 7•9•6 + 9•7•6 + 9•8•7 + 9•7•8 + 7•9•8 + 9•8•7) / 29•28•27 = 3,360/21,924
Answer:
18 and 54
Step-by-step explanation:
Each ticket = 4t
75 left over
Must be equal to or greater than 400
The inequality would be
4t + 75 ≥ 400
