Count the possible combinations of r letters chosen from the given list P.Q,R,S,T,U; r = 2

Tasya [4]

Answer:

<h2>There are 30 possible combinations of picking two letters.</h2>

Step-by-step explanation:

The combinations are defined as

$C^{r}_{n}=\frac{n!}{(n-r)!}$

Where $n$ is the total number of elements and $r$ is the number of letter we are gonna picke, which is two. Using this information, we have

$C^{2}_{6}=\frac{6!}{(6-2)!}=\frac{6!}{4!}=\frac{6 \times 5 \times 4!}{4!}=30$

Therefore, there are 30 possible combinations of picking two letters.

The sum of the speeds two trains is 717.6 miles per hour. If the speed of the first train is 6.4 mph faster than that of the sec

damaskus [11]

Train 1 = x + 6.4

Train 2 = x

(x) + (x + 6.4) = 717.6

2x + 6.4 = 717.6

2x = 711.2

x = 355.6

Train 1 = 355.6 + 6.4 = 362 mph

Train 2 = 355.6 mph

Hope this helps!! :)
