Sofia earned a score of 29 on Exam A that had a mean of 23 and a standard deviation of 5. She is about to take Exam B that has a mean of 350 and a standard deviation of 20. How well must Sofia score on Exam B in order to do equivalently well as she did on Exam A? Assume that scores on each exam are normally distributed.

complicated math or logic, let's go with the latter


23+5=28 to get to 29 you need 1/5th more of that standard deviation(5)


350+20=370 1/5th of that standard deviation(20) is 4, so 370+4 is 374
