Claudia has test scores of 78, 88, 84, 92, 76, 98. If she wants to end up with a ''B'' average, what does she need to score on her next test?
do you know what the mean is for those numbers.
What grade does she need to have a B?
80
add up is 516.. divide by 6 is 86 <--- is that answer she need to get on her next test
(78 + 88 + 84 + 92 + 76 + 98 + x) / 7 = 80
Absolutely yes or she could just get an 80.
To find out what Claudia needs to score on her next test in order to end up with a B average, we first need to know the grading scale or the range of scores for each grade. Let's assume that the average required for a B grade is between 80 and 89.
To calculate Claudia's current average, we add up all her test scores and divide by the number of tests she has taken. In this case, she has taken 6 tests.
Average = (78 + 88 + 84 + 92 + 76 + 98) / 6
Average = 516 / 6
Average = 86
Claudia's current average is 86. To maintain a B average, she needs to end up with a score between 80 and 89 on her next test.
Therefore, Claudia needs to score between 80 and 89 on her next test to end up with a B average.
