There was 3000 general admission tickets sold and 500 kid ticket sold.
How did I get this?
First, we need to see what information we have.
$2.50 = General admission tickets = (G)
$0.50 = kids tickets = (K)
There were 6x as many general admission tickets sold as kids. G = 6K
We need two equations:
G = 6K
$2.50G + $.50K = $7750
Since, G = 6K we can substitute that into the 2nd equation.
2.50(6K) + .50K = 7750
Distribute 2.50 into the parenthesis
15K + .50K = 7750
combine like terms
15.50K = 7750
Divide both sides by 15.50, the left side will cancel out.
K = 7750/15.50
K = 500 tickets
So, 500 kid tickets were sold.
Plug K into our first equation (G = 6k)
G = 6*500
G = 3000 tickets
So, 3000 general admission tickets were sold,
Let's check this:
$2.50(3000 tickets) = $7500 (cost of general admission tickets)
$.50(500 tickets) = $250 (cost of general admission tickets)
$7500 + $250 = $7750 (total cost of tickets)
No.

Square root is a non-linear function. sqrt(a +b) ≠ sqrt(a) +sqrt(b)
Answer:
Ratio of Non Fiction : Fiction books = 7 : 6
Step-by-step explanation:
Total number of books checked out = 52
Number of fiction books checked out = 24
So, number of non fiction books = Total books - number of fiction books
Or, number of non fiction = 52 - 24 = 28 books
Now, ratio of Non Fiction : Fiction books = 28 : 24
Solving the ratio term in its lowest form, we get
The Ratio of Non Fiction : Fiction books = 7 : 6

You only need to consider the situations where 10 or 11 of the babies are girls, then subtract those probabilities from 1. This will give probability that any other number up to 9 of the babies are girls.
Use binomial theorem.

n = 11
k = 10,11
p = 1/2
