Quiz 1-
1. You are asked to find the slope intercept form of the equation for a straight line and you are told that these two points are on that line: (x, y) = (10, 20) and (12, 18).
2. You are asked to find the slope intercept form of the equation for a straight line and you are told that the reciprocal of the slope is -1/2 and that the line contains the point (Q, P) = (10, 10).
3. You are taking a course in chemistry this semester and the course has three exams that will determine your grade. The first exam counts as 20% of your grade, the second exam counts as 30% of your grade, and the third exam counts as 50% of your grade. Suppose you need a total of 90 weighted points on a 100 point scale in order to get an A in the class. If your first two exam scores are both 80, what score do you need to make on the third exam? Show your work here and how you would approach this problem. It is all right to round to the nearest whole number for your answer-but you must show your work or verbalize your reasoning to get credit for your answer.
4. You are taking a class in the statistics department and you have already gotten two scores back from exams. On the first exam you made a 36 out of a possible 75 points and on the second exam you made a 21 out of a possible 30 points. Both exams are being given equal weight in the calculation of your final grade. Convert these scores to a 100 point scale and then provide your average based upon these two scores as measured on a 100 point scale. Show your work here and how you would approach this problem. It is all right to round to the nearest whole number for your answer-but you must show your work or verbalize your reasoning to get credit for your answer.
