The probability is 1/3.

Probability is sincerely how likely something is to show up. whenever we're unsure about the final results of an event, we will communicate about the probabilities of positive consequences—how probably they're. The evaluation of events governed by way of possibility is called information.

Probability is the branch of mathematics concerning numerical descriptions of ways likely an occasion is to arise, or how in all likelihood it's far that a proposition is actual. The opportunity of an event is more than a few among 0 and 1, wherein, kind of talking, zero suggests impossibility of the occasion and 1 shows the truth.

Chance = the wide variety of approaches to achieving achievement. the whole range of viable consequences. as an example, the opportunity of flipping a coin and its being heads are ½ because there may be 1 manner of getting a head and the overall wide variety of feasible results is two (a head or tail). We write P(heads) = ½.

lesya692 [45]

Answer:

3 assignments incomplete.

Step-by-step explanation:

context: 75% can be rewritten as 0.75

12 × 0.75 = 9 assignments completed.

The above equation shows the amount of assignments that have been already completed. In order to find out how many assignments she has yet to have completed, we need to subtract these amounts.

12 - 9 = 3 assignments incomplete.

E^y*cos x = 1 + sin(xy)
lys-0071 [83]
I assume you are studying implicit differentiation. Solving for dy/dx.
For the Left side use product rule. For Right side, use chain rule. Remember any time you take derivative of "y-term" you must multiply it by dy/dx.

---> \frac{dy}{dx} e^y cos (x) - e^y sin(x) = (y + x \frac{dy}{dx}) cos (xy)

Get dy/dx terms on one side:
\frac{dy}{dx} e^y cos (x) - \frac{dy}{dx} x cos(xy) = e^y sin(x) + y cos (xy)

Factor out dy/dx and solve:
\frac{dy}{dx} (e^y cos (x) -  x cos(xy)) = e^y sin(x) + y cos (xy)   \\.......\\ \frac{dy}{dx} = \frac{e^y sin(x) + y cos (xy) }{e^y cos (x) -  x cos(xy)}
