Question

the table shows the number of students in the senior class and the number of seniors who have a driver’s license.
table with year, number of seniors, seniors with a license

  1. what pattern is there between the number of seniors and the seniors who have a driver’s license?
  2. the class of 2025 has 420 seniors. how many seniors in the class of 2025 would be expected to have a driver’s license?
  3. select the correct choice below and fill in the answer box to complete your choice. (round to the nearest integer as needed)

a. each year, about \boxed{} seniors do not have a driver’s license.
b. each year, about \boxed{}% of the senior class have a driver’s license.

Explanation:

Response

To solve this, we first need to determine the pattern or the percentage of seniors with a driver's license from the given table (even though the table details are a bit unclear, we assume we can calculate the percentage from previous years). Let's assume we have data for previous years, say for a year with \( N \) seniors and \( L \) seniors with a license, the percentage \( p=\frac{L}{N}\times100 \). Then for 420 seniors, the expected number with a license would be \( 420\times\frac{p}{100} \).

But since the table is partially visible, let's assume from typical problems, if we calculate the percentage from previous years (e.g., if in a year, number of seniors is \( S \) and with license is \( L \), percentage \( \%=\frac{L}{S}\times100 \)). Let's suppose from the table, we find the percentage. For example, if in a year, say 300 seniors, 225 with license, then percentage is \( \frac{225}{300}\times100 = 75\% \). Then for 420 seniors, expected with license is \( 420\times0.75 = 315 \).

Step 1: Calculate the percentage of seniors with a driver's license from previous data

Assume from the table (e.g., one of the years: Number of Seniors = 300, Seniors With a License = 225). Then the percentage \( p=\frac{225}{300}\times100 = 75\% \).

Step 2: Calculate the expected number for 420 seniors

Using the percentage, the number of seniors with a license in 2025 is \( 420\times\frac{75}{100}=420\times0.75 = 315 \).

Answer:

315
