The admissions office at a public university estimates that \(65 \%\) of the students offered admission to the class of 2019 will actually enroll. a. Find the linear function \(y=N(x),\) where \(N\) is the number of students that actually enroll and \(x\) is the number of all students offered admission to the class of \(2019 .\) b. If the university wants the 2019 freshman class size to be 1350 , determine how many students should be admitted.

Short Answer

Expert verified
The university should admit 2077 students to meet the freshman class size of 1350.

Step by step solution

01

Understanding the Enrollment Rate

The problem states that 65% of the students offered admission will actually enroll. This means if \( x \) is the total number of students offered admission, then \( N(x) = 0.65x \) students are expected to enroll.
02

Constructing the Linear Function

Given the relationship from Step 1, we can formulate the linear function as \( y = N(x) = 0.65x \). This function gives us the expected number of enrolled students \( y \) based on the number of students offered admission \( x \).
03

Setting the Enrollment Goal

The university wants the freshman class size to be 1350 students. This means \( N(x) = 1350 \).
04

Solving for the Number of Students to Admit

To find \( x \), we rearrange the equation from Step 2: \[ 0.65x = 1350 \]. Dividing both sides by 0.65 gives \[ x = \frac{1350}{0.65} \].
05

Calculating the Result

Perform the division to find \( x \): \[ x = \frac{1350}{0.65} \approx 2076.923 \]. Since the number of students must be a whole number, we round up to 2077 as you can't admit a fraction of a student.

Key Concepts

These are the key concepts you need to understand to accurately answer the question.

Understanding Student Enrollment
Student enrollment refers to the process where students officially register or enroll in an educational institution. In our scenario, this process is represented as a fraction or percentage of those who have successfully gone through the admissions process.
The university expects that a specific percentage of admitted students will choose to enroll. This percentage is crucial for planning, as it influences the university's resource allocation, class sizes, and overall student body.
Understanding this concept is essential for determining how many offers of admission need to be made to meet a desired enrollment number. This understanding ensures that the university offers enough admissions to achieve its target enrollment without overextending its capacity.
Demystifying the Admissions Process
The admissions process involves evaluating applicants and deciding which students will be offered a spot in the university. This is a critical phase that involves several steps:
  • Application Submission: Students send their applications for admission, usually including their academic records, test scores, and personal statements.
  • Evaluation: The university assesses these submissions to identify suitable candidates.
  • Offer of Admission: Successful applicants receive an offer to join the university's next intake.

In our example, understanding the admissions process is key to calculating how many offers of admission to make in order to hit an enrollment target. When planning, universities must consider their expected enrollment rate based on past data, allowing them to align admissions strategies with their capacity and goals.
Effective Problem Solving Steps
Effective problem solving involves breaking a problem down into manageable steps and solving it systematically. Let's review the steps for solving the enrollment exercise:
Start by identifying the given information. Here, we know the enrollment rate is 65%, and the desired number of students is 1350.
Next, formulate a linear function that models the situation. In this case, the function is \( N(x) = 0.65x \), where \( N(x) \) represents the number of enrolled students.
The subsequent step is setting the goal by equating this function to the target enrollment. Here, it's set to 1350, giving us the equation \( 0.65x = 1350 \).
Finally, solve for the unknown by isolating \( x \). Divide both sides by 0.65 to get \( x = \frac{1350}{0.65} \), resulting in approximately 2077 when rounded.
  • Tackle each part of the equation methodically.
  • Check your work by ensuring the calculation makes logical sense in the context of the problem.

By mastering these steps, students enhance their problem-solving skills, useful not only in mathematical contexts but also in real-world applications.
