If there are 40 children aged twelve and under and x of them are under three years old, 40 - x aged three twelve years old. From the 92 people that where taken by the company on whale watching trips, 52 are over twelve years old. The equation that best show the total cost, C is
(40 - x)(36) + (52)(48) = C
Rearranging the equation gives,
x = 40 - ((C - 2496)/ 36)
A geometric sequence with first term "a" and common ratio "r" has "nth" term:
ar^(n-1)
And the sum of a geometric sequence with "n" terms, first term "a," and common ratio "r" has the sum "a(r^n - 1)/r - 1.

Answer:
The probability that you will get 3 pictures right is 0,015625
Step-by-step explanation:
To get the probability, equally likely, of guessing the picture we use the following formula
P=# of possibilities that meet the condition / #of equally likely possibilities.
# of possibilities that meet the condition= 2
#of equally likely possibilities= 8
So every time you guees you have 2 possibilities from 8 , that give us a probability of 2/8 or 1/4
We suppose once you guess 1 card , the tester put back the card with the others.
Now, we must guess 3 pictures, that will be the multiplication of each probability.
P= 1/4 *1/4*1/4
P= 0,015625
