''36'' atp molecules would be the answer
X2 - 8x + 15 = 0
(x - 3)(x - 5) = 0
critical points are at 3 and 5
Answer:
As eq of line passing through 2 points is
y-y1 = (y2-y1)/(x2-x1) ][ x -x1)
where (X1,y1)( x2, y2) denotes points lying on line
substitute (X1 ,y1) by( -1,-2) and (X2,y2) by( 2,4)
y+2 = 6/3 )( x+1)
y+2= 2x +2
y = 2x is required equation
Easy
so remember
4 aces in a deck
probability =(desired outcomes)/(total possible)
total possible=52
4/52=1st card
then since he picked 1 out the total possible is and assuming he drwe an ace 3/51
so the answer is 4/52 times 3/51=1/221
