Answer:
The sample is 250 first-year students of the Concordia University
Step-by-step explanation:
When you are making a research you have to take into account two elements: The population and the sample.
The population refers to ALL the individuals that have the characteristic you are investigating, in this case the population of the researcher is the first year students al Concordia University, because he want to estimate the textbook costs for this students because it is not taken into account in the college costs.
The problem is thar if there are a thousand students of first year or more it will be very difficult to make the study because you he will need more resources, more time, and he will have to analyze more information, that's why he takes a SAMPLE that represent the whole population that in this case correspond to 250 first-year students of the Concordia University, this students will represent the population and as a conclusion of his work, he must say that in the costs of college education it must be include other costs such as textbook cost, because in average they have a cost of $300 per semester that must be added to the tuition cost.
Answer:
The number of adult tickets sold was 121
Step-by-step explanation:
The general equation is: <em>S</em> + <em>A</em> = <em>T</em> ;where <em>S</em> means student tickets, <em>A</em> means adult tickets and <em>T</em> means total tickets. We know that <em>S</em> is two times <em>A</em> and <em>T</em> is 363. So, <em>S</em> will be 2x and A will be x. Then, the new equation is 2x + x = 363.
<em>S</em> + <em>A</em> = <em>T</em>
2x + x = 363
3x = 363
x = 363 / 3
x = 121
Adult tickets: <em>A</em> = x = 121
Student tickets: <em>S</em> = 2x = 2 * 121 = 242
Complementary angles are two angles whose measures add to a sum of 90 degrees. This can be expressed as the following formula:
A1 + A2 = 90
Substitute any known values into the equation above:
(2x + 1) + (x – 7) = 90
2x + 1 + x – 7 = 90
Combine like terms:
3x – 6 = 90
Add 6 to both sides of the equation:
3x = 96
Divide 3 from both sides of the equation:
x = 32
When (2x + 1) and (x – 7) are complementary, “x” is equal to 32.
I hope this helps!
