A proportional relationship is also a direct variation.
The general equation of direct cvariation is

y = kx,

where k is a number.

In your case, if k = -1, then y = kx becomes y = (-1)x which is the same as

y = -x

The digits 1,2,3,4,5,6,7 and 8 are arranged randomly to form a three-digit number find the probability that the number is even a
Korvikt [17]
So each digits can only be selected once.

Let's start counting desired outcome.

Hundred position need to be at least 8. There is only one possible digits. So we will go with 8 and then there are 7 remaining digits.

One position can only be 2,4,6. because we need number to be even. So that's 3 possible digits. We will take one. 6 digits remaining.

Ten position can be anything so that would be 6 possible digits.

So the number of desired outcomes is 3·6 = 18.

Now count all outcomes.

Hundred, ten, and one position can get any digits

So that's 8·7·6 = 336

So the probability would be 18 / 336 = 3 / 56 ≈ 0.0536

Hope this helps.

mr Goodwill [35]

Use the next convertion factors:

60 seconds are equal to 1 minute

60 minute are equal to 1 hour

24 hours are equal to 1 day in earth

9.98\times10^4s\cdot\frac{1\min}{60s}\cdot\frac{1h}{60\min}\cdot\frac{1\text{day}}{24h}\approx1.15\text{day}<h2>Then, there are approximately 1.15 earth days in a Mar's day</h2>
