lakkis [162]

Answer: 680

Step-by-step explanation:

When order doesn't matter,then the number of combinations of choosing r things out of n = $^nC_r=\dfrac{n!}{r!(n-r)!}$

Given: Total participants = 17

From these, a group of 3 participants is to be tested under a special condition.

Number of groups of 3 participants chosen = $^{17}C_3=\dfrac{17!}{3!(17-3)!}\$

$^{17}C_3=\dfrac{17!}{3!(17-3)!}\\\\=\dfrac{17\times16\times15\times14!}{3\times2\times14!}\\\\=680$

Hence, there are 680 groups of 3 participants can be chosen,.

Two jets leave an airbase at the same time and travel in opposite directions, One jet travels 71mi/h faster than the other. If t

KATRIN_1 [288]

jet1 = 549 mi/h

jet2 = 620 mi/h

x= jet1

x + 71 = jet2

6 hours

6 * x

6 * x + 71

6x + 6x + 426 = 7014

12x = 7014 - 426

12x = 6588

x = 6588/12

x= 549

x + 71 = 620
