Sample Space ={5 Red, 8White, 2 Blacks} = 15 possible outcomes.
Favorable outcomes={5 Red}
1) P(drawing 1st Red) = 5/15
2) P(drawing ANOTHER RED) = 4/14 (because one Red already drawn and NOT replaced, so the remaining Red are now 4 and the new sample space is now 14, since 1 red already drawn), Hence
P( 1 Red AND another Red) = (5/15).(4/15) or:
"5 over 15 multiplied by 4 over 14"
This isn’t a math equation

Answer:
The graph g(x) is the graph f(x) vertically stretched by a factor of 7.
Step-by-step explanation:
Quadratic Equation: f(x) = a(bx - h)² + k
Since we are modifying the variable <em>a</em>, we are dealing with vertical stretch (a > 1) or vertical shrink (a < 1). Since a > 1 (7 > 1), we are dealing with a vertical stretch by a factor of 7.
2 + 3x = 4 + 2x + x^2
x^2 - x + 2 = 0
(x - 0.5)^2 - 0.25 + 2 = 0
(x - 0.5)^2 = -1.75
x - 0.5 = +/- sqrt 1.75 * i
x = 0.5 + 1.32i , 0.5 - 1.32i answer
