Question

the table shows the number of students in the senior class and the number of seniors who have a drivers license.

1. what pattern is there between the number of seniors and the seniors who have a drivers license?
2. the class of 2025 has 410 seniors. how many seniors in the class of 2025 would be expected to have a drivers license?
3. select the correct choice below and fill in the answer box to complete your choice.

(round to the nearest integer as needed.)
o a. each year, about % of the senior class have a drivers license.
o b. each year, about seniors do not have a drivers license.

Explanation:

Step1: Calculate the percentage of seniors with a driver's license each year

• For 2021: $\frac{208}{340}\times100\%\approx61.18\%$
• For 2022: $\frac{225}{359}\times100\%\approx62.67\%$
• For 2023: $\frac{185}{304}\times100\%\approx60.86\%$
• For 2024: $\frac{231}{378}\times100\%\approx61.0\%$
• Average percentage: $\frac{61.18 + 62.67+60.86 + 61.0}{4}\approx61.43\%$

Step2: Calculate the number of seniors expected to have a driver's license in 2025

• Number of seniors in 2025 is 410.
• Number of seniors with license: $410\times61.43\%\approx252$

Step3: Calculate the number of seniors not expected to have a driver's license in 2025

• Number of seniors not with license: $410 - 252=158$

Step4: Calculate the percentage of seniors with a license (for part A)

• Percentage: $\frac{252}{410}\times100\%\approx61.5\%$

Answer:

A. Each year, about $62\%$ of the senior class have a driver's license.
B. Each year, about $38\%$ seniors do not have a driver's license.
