Step-by-step explanation:
For quadratic equation ax^2 + bx + c = 0 to have two distinct real roots,
b^2 - 4ac must be positive.
b^2 - 4ac > 0
(k - 3)^2 - 4(3 - 2k) > 0
k^2 - 6k + 9 - 12 + 8k > 0
k^2 + 2k - 3 > 0
Answer:
the probability of rain is 0.3. The probability of no rain is 1–0.3= 0.7
0.7 is the probability that it does not rain.Step-by-step explanation:
Plug in two values for x, say, 0 and 1.
Lets start with solving the equation when x=0.
y=2(0)-3
y=0-3
y=-3.
So, when x=0, y=-3. Graph (0, -3)
Next, x=1
y=2(1)-3
y=2-3
y=-1
So, when x=1, y=-1. Graph (1,-1)
Draw a line between the two points, and that should be your answer! Hope this helped :)
3 drops : 4 pints = x drops : 16 pints
3drops/4pints = x/16pints
(3drops/4pints)*16pints = x
*cancel pints unit*
(3drops/4)*16 = x
(16*3)drops/4 = x
48 drops / 4 = x
12 drops = x (ANSWER)
