xy = (1/2) (1/4) = 1/8
2x + y = 5 → y = 5 - 2x (1)
4y + 8x = 1 (2)
Sub (1) into (2)
4 [ 5 - 2x ]+ 8x = 1
20 - 8x + 8x = 1
20 = 1 → no solution....these are parallel lines
The total number of possible committies = C(14,3) = 364
And we want to choose any 1 of the 7 females and any 2 of the 7 males....so we have...
C(7,1) * C(7,2) = 147
So...the probability = 147 / 364 = 147/364 = 21/ 52 ≈ 0.4038 ≈ 40.38%
3+(6*4)-2 =
3 + (24) - 2 =
27 - 2 =
25
You're on a roll....!!!!!
Pork.....
LOL!!!
HAHAHA!!!!...it was nothing....really.....
Good job, HeyxJacq....!!!
Be careful, here....
(-3)^2 = (- 3) (- 3) = 9 ......however.....
-3^2 = - (3)(3) = - 9 .... the exponent doesn't appyl to the " - "
