(3x^4)^2 = (3^2)*(x^4)^2 = 9*(x^(4*2)) = 9*x^8 . . . . . the 3rd selection
A is the the answer 200 adults
This is fairly complex, but looks like fun.
So first lets count how many bids are made till the bidding goes up to 160.
That is 100*160=16000
How much will be your random bid. Each bid has equal chance so it is the avarge of all bids. (1cent + 160dollars)/2 = 80dollars (rounded)
What is your chance of winning: 1 bid wins out of 16000 so 1/16000.
When you win your profit is 2000-80dollars=1920
1920/16000= 0.12 dollars
You entering the bidding costs 1 dollar and your average win is 0.12
This the outcome is 0.12-1=-0.88 dollars
Answer:
c) $200
Step-by-step explanation:
if the farmer wishes to earn $1500 per year he needs 1500/75=20 trees producing fruit
Because each tree produces 75$ of fruit per year
if we wants 20 trees he has to spend 20*$10=$200
Because each tree has a cost of 10$
