Y = mx + b...subtract b from both sides
y - b = mx...now divide both sides by x
(y - b) / x = m
Answer:
D
Step-by-step explanation:
In probability,
a probability of 0 means that it is IMPOSSIBLE, sure that this event WILL NOT occur, ever. So, probability of anything less than 0 is not possible.
On the other hand, probability of 1 means that it is CERTAIN to happen. So, probabilty of anything greater than 1 can't happen.
So we can say:
0 <= Probability of an Event happening <= 1
Option A is 1/2, which is in the middle, so this is OKAY.
Option B is 10%, which is certainly close to 0 and between 0 and 1, so this is OKAY.
Option C is 0.7, which is close to 1 and greater than 0, so in between 0 and 1, certainly. So this is OKAY.
Option D is 3/2 which is 1.5, so this is GREATER THAN 1, so it can't ever be possible.
Option D is the correct choice.

Step-by-step explanation:
Answer:
i)W = 2500 / T
ii) W = 500 Tons
iii) grad W(10°) = - 25î
iv) The formulation is not practical
Step-by-step explanation:
i) Write an equation describing the use of coal
As use of coal is inversely proportional to the average monthly temperature
if W is use of coal in tons/per month then
W(t) = k / T where k is a constant of proportionality and T is the average temperature in degrees. We have to determine k from given conditions
k = ?? we know that when T = 25° W = 100 tons the by subtitution
W = k/T 100 = k /25 k = 2500 Tons*degree
Then final equation is:
W = 2500 / T
ii) Find the amount of coal when T = 5 degrees
W = 2500 / 5
W = 500 Tons
iii)
The inverse proportionality implies that W will decrease as T increase.
The vector gradient of W function is:
grad W = DW(t)/dt î
grad W = - 2500/T² î
Wich agrees with the fact that W is decreasing.
And when T = 100°
grad W(10°) = - 2500/ 100 î ⇒ grad W(10°) = - 25î
iv) When T = 0 The quantity of coal tends to infinite and the previous formulation is not practical
