Answer:
21 matches
Step-by-step explanation:
This is a combination problem where we have to select two member out of 7 members
So we want calculation of 7C2
7C2 = 7!/[(2!)(7-2)!]
(7*6*5*4*3*2*1)/[(2*1) *(5*4*3*2*1]
(7*6)/2 ~ Note everything that easily cancels here!
42/2
21 matches

Answer:
a. √9
Step-by-step explanation:
a. √9 = 3
b.√15 = sqrt(5*3) cannot be simplified
c. √18 = sqrt(9) sqrt(2) = 3 sqrt(2) cannot be simplified farther
d. √20= sqrt(4) sqrt(5) = 2 sqrt(5) cannot be simplified farther
a is the only answer that is a rational number
0.6431 if not rounded off
0.6432 if rounded off
