Answer:
Sample
Step-by-step explanation:
The term that represents the description in the question is called sample.
Take for instance:
- 40 students selected from a class of 100
- 1000 people selected from a population of 100000
In the above descriptions:
40 and 1000 represent the samples while 100 and 100000 represent the populations, respectively.
Another example is when 10 cats are picked from an animal farm in order to study their eating pattern.
All these and many more represent sample.
First we need to find a common denominator
=
now we can add them
+
=
Answer:
Adult= $11
Children = $7.5
Step-by-step explanation:
Let x represent adult ticket and y represent children ticket
2x + 3y= 44.50........equation 1
3x + 6y= 78........equation 2
From equation 1
2x + 3y= 44.50
2x= 44.50-3y
x= 44.50-3y/2
Substitute 44.50-3y/2 for x in equation 2
3x+ 6y= 78
3(44.50-3y/2) + 6y= 78
66.75- 4.5y +6y= 78
66.75 + 1.5y= 78
1.5y= 78-66.75
1.5y= 11.25
y= 11.25/1.5
y = 7.5
Substitute 7.5 for y in equation 1
2x + 3y = 44.50
2x + 3(7.5)= 44.50
2x + 22.5= 44.50
2x = 44.50-22.5
2x= 22
x= 22/2
x= 11
Hence the price of adult ticket is $11 and the price of children ticket is $7.5
Answer:
$6.61
Step-by-step explanation:
3 * 1.89 = 5.67
1.89/2 = 0.945
5.67 + 0.945 = 6.615
= 6.61
