Question

IV Per data form the registrar's office at QCC there were 12500 students enrolled in 2000. Currently there are 8967 students enrolled. What is the geometric annual rate of enrollment? V Assume that A = 96, B = 87, C = 78 and D = 65. Assume a student needs at least a D to past this class. A student has the following grades; exam I = 98 exam, exam II = 88 and exam III = 83. How much should the student score on exam IV to get at least an A in this class. How much should a student score to at least past this class.

Explanation / Answer

(IV) as there are 17 years since 2000 to 2017

hence geometric annual rate =1-(8967/12500)1/17 =1-0.0422=0.9578 or a decrease of 4.22% per annum

V) for at least A average =96 =(98+88+83+IV)/4

hence class iV score should be =115

2) for at least pass 65=(98+88+83+IV)/4

hence class iV score should be =-9
