The longest side of a triangle is two times the shortest side, while the medium side is 3 meters more than the shortest side. Th

mylen [45]

Let $s,\ m\, l$ be the short, medium and long side, respectively. If we translate all the information into formulas, we get the following system:

$\begin{cases} l = 2s\\ m=s+3\\ s+m+l = 27 \end{cases}$

Using the second equation, we can express the middle side in terms of the small one, and reduce the system to two equations in two unknowns:

$\begin{cases} l = 2s\\ s+(s+3)+l = 27 \end{cases}$

And thus

$\begin{cases} l = 2s\\2s+l = 24 \end{cases}$

But then again, using the first equation, the third becomes

$2s+l = 24 \iff l+l = 24 \iff 2l = 24 \iff l=12$

So, the longest side is 12. Since the small is half the long, we have $s = 6$ . Finally, the medium is three more of the small, so we have $m = 6+3 = 9$

The waiting times between a subway departure schedule and the arrival of a passenger are uniformly distributed between 0 and 5 m

Grace [21]

Answer:

0.35

Step-by-step explanation:

we know that

The formula to use for uniform distribution is equal to

$P( X < x) = \frac{x-a}{b-a}$

where,

b is the upper limit of the distribution which is 5 minutes in this case.

a is the lower limit of the distribution which is 0 minutes in this case.

x is the concerned value which is 1.75 minutes in this case.

substitute the given values

$P( X< 1.75) = \frac{1.75-0}{5-0}=0.35$

That means

The probability that a randomly selected passenger has a waiting time less than 1.75 minutes is 0.35
