(PLEASE HELP) A contractor has 10 lots for sale to build on. 4 lots are greater than two acres. 6 lots are less than two acres.

charle [14.2K]

Probability that the first lot sold will be less than two acres = number of lots less than two acres / total number of lots = 6/10 = 3/5

Probability that the second lot sold will be less than two acres = remaining number of lots less than two acres / remaining total number of lots = 5/9

Required probability = 3/5 x 5/9 = 15/45 = 1/3

Let f(x)=-3x-7 Abe g(x)=4x-5 find (f•g)(-3)

LiRa [457]

Answer:

272

Step-by-step explanation:

note that (f • g)(x) = f(x) × g(x) = (3x - 7)(4x - 5)

To evaluate substitute x = 3 into (3x - 7)(4x - 5)

(f • g)(- 3) = (- 9 - 7)(- 12 - 5) = - 16 × - 17 = 172
