X21) The FFA has $2400 in a fund to raise money for a new tractor. They are selling trees and have determined that the number of trees they can buy to sell depends on the price of the tree p, according to

the function n(p) = 2400. Also, after allowing for profit, the number of trees that customers will

purchase depends on the price which the group purchased the trees with function cp) = 300 - 6p. For

what price per tree will the number of trees that can be equal the number of trees that will be sold?

0.16 or 16%

step-by-step explanation:

lets take a coin for example.

if you toss it twice, it has a 1/4 chance of landing on heads both times because 1/2 * 1/2 is 1/4.

with the cards, the chance of picking dog is 0.4. having two people pick one is like picking a card twice in a row. so 0.4 * 0.4 is 0.16, or 16%

i think the answer is b.

step-by-step explanation:

not 100% sure though.

step-by-step explanation:

we can analyze the pattern at which the terms increase. let us denote , , , so that we can call

note the following:

the pattern: to get the next term value, we just add the next term number (e.g. 1st, 2nd, to the previous term value (term values are the given numbers in the question, 1, 3, 6, 10, 15,

from , to get to , we add

from , to get to , we add

etc.

we need to form a recursive formula, a formula that has the next term as a function of the previous term. so a possible recursive formula can be

, and for

i think its 5.6 but i dunno for sure.
