The group of numbers when systematically arranged is called the set. The number of set for the given set is 5.
Given information
The set given in the problem is,
Combination is the number of possible arrangement for the given data set without repetition.
The group of numbers when systematically arranged is called the set.
The number of element in a set is represented as,
The number of set for the given set has to find out. As there is total 5 number are given in the set. Thus,
Hence the number of set for the given set is 5.

n(C) = #of items in C
n(C) = 5
The ticket for an adult costs $10 and the ticket for a child costs $7
Based on the information given, the equation to solve the question will be:
2a + 4c = 48
5a + 2c = 64
Multiply equation i by 5
Multiply equation ii by 2
10a + 20c = 240
10a + 4c = 128
Subtract the equations
16c = 112
c = 112/16
c = 7
The ticket for a child is $7
Since 2a + 4c = 48
2a + 4(7) = 48
2a + 28 = 48
2a = 48 - 28
2a = 20
a = 20/2
a = 10

Answer:
The price for one adult is $10 while the price for one child is $7
Step-by-step explanation:
Let
price for an adult = a
price for a child = b
2a + 4b = 48.............(i)
5a + 2b = 64.............(ii)
make a subject of the formula in equation (i)
2a = 48 - 4b
divide through by 2
a = 24 - 2b
Insert the value of a in equation (ii)
5(24 - 2b) + 2b = 64
120 - 10b + 2b = 64
collect like terms
- 8b = 64 - 120
-8b = -56
divide both sides by -8
b = 7
insert the value of b in equation(i)
2a + 4(7) = 48
2a + 28 = 48
2a = 48 - 28
2a = 20
divide both sides by 2
a = 10
The price for one adult is $10 while the price for one child is $7

Answer:
radius:
Step-by-step explanation:
Answer:
The average of -2.5, 5.2, 1.7, and -0.8 is 0.9
Step-by-step explanation:
You are taking the mean of all the values
So you would add -2.5, 5.2, 1.7, and -0.8 all together
This gives you 3.6
Then you would divide by the number of numbers per se,
Which would give you the answer: 0.9
