You can work these in your head if you consider the revenue generated by the least contributor (children's tickets) and the difference in revenue between that and the larger contributor ($2.00 -1.50 = 0.50).
If all were children's tickets, the revenue would be 500*$1.50 = $750.00. The actual revenue exceeded that amount by $862.50 -750.00 = 112.50. This difference in revenue is made up by the sale of $112.50/$0.50 = 225 adult tickets. Then the number of children's tickets is 500 -225 = 275.
225 adult tickets were sold
275 children's tickets were sold.
_____
If you need an equation, you can write an equation using a variable for the number of adult tickets sold (the largest contributor).
.. (500 -a)*1.50 +a*2.00 = 862.50
.. 0.50a = (862.50 -750.00) . . . . . does this look familiar, yet?
.. a = 112.50/0.50 = 225
Answer:
(3,4) -> (8,3)
(-2,4) -> (3,3)
(-2,5) -> (3,4)
The triangle is translated 5 units to the right and 1 unit down.
Step-by-step explanation:
Add 5 to each x on the (x,y) coordinate and subtract 1 from each y.
Answer:
0.0185 = 1.85% probability that 5 randomly selected blood donors in NYC all have Group O blood.
Step-by-step explanation:
For each donor, there are only two possible outcomes. Either they have type O blood, or they do not. The donors are selected randomly, which means that the probability of a donor having type A blood is independent from other donors. So we use the binomial probability distribution to solve this problem.
Binomial probability distribution
The binomial probability is the probability of exactly x successes on n repeated trials, and X can only have two outcomes.
In which 
is the number of different combinations of x objects from a set of n elements, given by the following formula.
And p is the probability of X happening.
In New York City, 45% of all blood donors have type O blood.
This means that 
.
Find the probability that 5 randomly selected blood donors in NYC all have Group O blood.
This is 
when 
. So
0.0185 = 1.85% probability that 5 randomly selected blood donors in NYC all have Group O blood.
Answer:
1/32
Step-by-step explanation:
Weight of package of cheese = 1/4 pound
no of slice in package = 8 slice
Weight of each slice can be calculated by
dividing total weight of package of cheese by no of slice in package
mathematically we have
Weight of each slice = total weight of package of cheese/no of slice in package
Weight of each slice = (1/4 )pound / 8 = 1/(4*8) = 1/32 pound
Each slice is 1/32 fraction of a pound
Answer:
6 cubes.
Step-by-step explanation:
By looking at the picture attached we find that the only cubes that will have only once face painted are the ones located in the middle. The cubes near to the edge will have at least two faces painted.
Given that a cube has 6 faces, we can conclude that only 6 small cubes will have one face painted.
