Answer:
503 $1 tickets sold.
Step-by-step explanation:
Use two equations
Let x = number of $1 tickets sold
Let y = number of $1.50 tickets sold
x + y = 739
1x + (1.5)y = 857
First equation ==> y = 739 - x
Plug this into the second equation
x + (1.5)(739 - x) = 857
x + 1108.5 - 1.5x = 857
- 0.5x = -251.5
x = 503
There were 503 $1 tickets sold.
To find the number of $1.50 tickets, just plug this value of x into either one of the equations.
(503) + y = 739 (739 - 503 = 236)
y = 236
There were 236 $1.50 tickets sold.
Answer:
Step-by-step explanation:
17x – 7y = 19
17x – 19 = 7y
y = (17/7)x - 19/7
10+5x=7x-4
1. simplify 7x - 5x
10=2x-4
2. add four to both sides
10+4=2x
+ 4 4
14=2x
3. divide 14 to both sides
14=2x
x=7
Answer:
Collection of numerical information is called Statistics
Step-by-step explanation:
From the Oxford dictionary, the definition of statistics (science) is: "the practice or science of collecting and analyzing numerical data in large quantities, especially to infer proportions in a whole from those in a representative sample".
While the definition of statistic (data) is: "a fact or piece of data obtained from a study of a large quantity of numerical data".
Statistics is a science, not a method, therefore answer can´t be a).
Not all sample data is necessarily a statistic, therefore answer can´t be b).
All statistics are numerical information.
Not all statistics are population data, therefore answer can´t be d).
Cleaned data is information filtered with a specific criterion, but not necessarily used in a statistic.
The most probable answer is c.
