945 is your answer but what number blank?
If you ask 100 people and 60 say they are students, then you would assume that 60/100 people in town as a whole are students. To estimate the non-student population, you would infer that the other 40 are not students, thus making the non-student to student ratio 40:60 or 2:3 when simplified. This means that for every 2 non-students, there are 3 students. If we multiply 2000 by this 2:3 ratio, we would see that 2/3*2000 = the non-student population.The non-student population is estimated at 1,333.
A right triangle follows the Pythagorean theorem: a^2 + b^2 = c^2
Let’s work out the problems
1. 20^2 + 72^2 = 75^2
40 + 5184 = 5625
False
2. 40^2 + 74^2 = 85^2
1600 + 5476 = 7225
False
3. 45^2 + 60^2 = 75^2
2025 + 3600 = 5625
True
The correct answer is (45, 60, 75)
