Answer: 405 students
Step-by-step explanation:
From the question, Banneker Middle School has 750 students and we are told that Lynn surveys a random sample of 50 students and finds that 27 have pet dogs. The number of students at the school that are likely to have pet dogs goes thus:
Since out of 50 students surveyed, 27 have pet dogs, this means we multiply the fraction by 750. This can be mathematically written as:
= 27/50 × 750
= 27 × 15
= 405
This means 405 students are expecting to have pet dogs.
You can use the given data to find out how many miles does the van travels for 1 gallon of gas. This will help you get the distance van can travel for full tank (16.2 gallons) of gas.
The considered van with full tank(16.2 gallons) can travel 362.88 miles
<h3>How to find the distance the van can travel per gallon of gas?</h3>
Since the considered van traveled 241.92 miles in 10.8 gallons, then we can take equal in dimension of input and output relation.

Thus, the considered van travels 22.4 miles per gallon of gas.
Now, since full tank consists of 16.2 gallons, thus, multiplying by 16.2 on both the sides, we get

Thus,
The considered van with full tank(16.2 gallons) can travel 362.88 miles
