Answer:
12.5%
Step-by-step explanation:
2.56-2.24 =0.32
By using the rule of three we can find the answer.
we have that 2.56 = 100% so we have to find what percentage 0.32 represents
(0.32*100)/2.56 = 12.5
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.
