find 7/30 of 600.
about how many employees at the company can dani expect to drive to the office?
20 employees 30 employees
140 employees 460 employees

Explanation:

Step1: Calculate the fraction of employees who drive in the sample

The sample has \(7 + 23=30\) employees. The fraction of employees who drive in the sample is \(\frac{7}{30}\).

Step2: Estimate the number of employees who drive in the whole company

To estimate the number of employees who drive in the whole company (with \(N = 600\) employees), we use the formula \(n=\frac{7}{30}\times600\).
