if my average is 88 percent. and if another grade is added, is it possible that my average would be the same
Yes.
It depends upon how many total scores there are as well as what the additional score is.
no it is not related to my question. my question is perimeter and area is 28 .find attitude
Yes, it is possible for your average to remain the same even after adding another grade. To determine if this is possible, we need to consider the weight or percentage of the new grade and its impact on the overall average.
Let's assume that the new grade will be weighted the same as the previous grades. In this case, we can create an equation to represent the average:
(88 + x) / 2 = 88
Where "x" represents the new grade (the percentage score for the added grade).
Simplifying the equation:
88 + x = 2 * 88
88 + x = 176
Subtracting 88 from both sides:
x = 88
Therefore, for your average to remain the same, the new grade would need to be 88 percent. However, if the weightage of the new grade is different, the calculation will vary accordingly. For example, if the new grade is not weighted as much as the previous grades, it would require a higher percentage to maintain the same average.
It's important to note that this explanation assumes the straight average calculation method, where all grades have equal weight. Different grading systems or weighting methods may lead to different calculations.
