Answer:
2/3
Step-by-step explanation:
:)
So there are 16 cokes in total...
the probability of selecting a cherry coke is 9/16
the probability of selecting a coke zero is 4/16
for there to be no replacement I guess you could combine diet cokes with coke zero because they are both cokes..
I don't know EXACTLY how to get the probability without a replacement.. sorry
Answer:
y - 8 = -2(x + 1)^2
Step-by-step explanation:
The vertex of this parabola is (-1, 8). It opens downward, so the x^2 term has a negative coefficient. The zeros are (-3, 0) and (1, 0), and the y-intercept is (0, 7).
Through the vertex form of the equation of a parabola we get:
y - (8) = a(x - (-1)) + 7, or
y - 8 = a(x + 1)^2. Find coefficient a by substituting the coordinates (-3, 0) in this equation:
0 - 8 = a(-3 + 1)^2, or
-8 = a(-2)^2, or a = -2
The desired equation is
y - 8 = -2(x + 1)^2
The answer would be 4,500 gallons left.
None of the given choices is the correct solution.
The setup of the problem is a correct, if somewhat weird, description
of the ideal gas laws, but the temperature involved in the law is the
ABSOLUTE temperature, NOT the Celsius or Fahrenheit one, or
any other scale where 'zero' is not 'Absolute Zero'.
Zero Celsius is (about) 273 Celsius-size degrees above Absolute Zero.
So the original temperature of the gas is (273 + 2.5) = 275.5 Kelvins
(Celsius degrees above absolute zero). THAT's the temperature that's
going to change in inverse proportion to the volume.
(if the pressure doesn't change)
The volume has been multiplied by 100cm³/500cm³ = 1/5 .
Since the temperature changes inversely, it will be multiplied by 5 .
Final absolute temperature = (5) x (original absolute temperature) =
(5) x (275.5 K) =
1377.5 K .
The final Celsius temperature is (1377.5 - 273) = <em>1104.5 °C</em>.
"But those are the choices in the assignment !"
Then the person who wrote the question in the assignment is wrong.
None of the choices they gave is correct.
