The distance between 1 and .5 is (1 - .5)/2 which is .25. Add that to .5 to get the number halfway between the points: .5 + .25 = .75.So the point halfway between is .75 or 3/4.

In order to find the distance between two coordinates, you first need to find the difference between the x and y coordinates. In this case, the difference between the x coordinates is 3-(-2) = 5. The difference between the y coordinates is -4-5 = -9. To find the distance you add up the squares of these differences then find the square root. 52 = 25. -92 = 81. 25+81 = 106. Thus the distance is the square root of 106, or approximately 10.296
If you miss 4 out of 25 questions, you would have answered 21 questions correctly. To calculate your score, you would typically assign a certain number of points to each correct answer. For example, if each question is worth 1 point, your score would be 21 points out of a possible 25, resulting in a score of 84%.
