To find Stacey's first test score, we can use the formula for average: (sum of all scores) / (total number of scores). Stacey's total score on three tests is 84 x 3 = 252. Her last two test scores total 79 + 93 = 172. To find her first test score, we subtract the total of the last two tests from the total score: 252 - 172 = 80. Therefore, Stacey's first test score was 80.
To calculate an average out of 90 points, first sum all the individual scores you want to include in the average. Then divide that total by the number of scores. Finally, to express the average out of 90, you can scale it by multiplying by 90 and dividing by the maximum possible score of the individual assessments if they are not already out of 90. For example, if your total score is 72 out of 100, the average out of 90 would be (72/100) * 90.
The median is the middle score in a set of data which is organised ascending (lowest to highest). In your set of data, it appears that this has already been done, which takes care of the first step. Then we count up the number of scores that have been recorded. In your case, this would be six. Since this is an even number, we take the 3rd and 4th scores, and find the average of them. So in this case:64 73 79 82 87 11079+82 = 161161 / 2 =80.5Therefore 80.5 is our median.However, in a case where there is an odd number of scores, the middle number should be selected (i.e. when there is nine scores the fifth should be selected).
To find the weighted average of four scores, first define the scores as ( S_1, S_2, S_3, ) and ( S_4 ) and their corresponding weights as ( W_1, W_2, W_3, ) and ( W_4 ). The algorithm can be expressed as: Calculate the weighted sum: ( \text{Weighted Sum} = (S_1 \times W_1) + (S_2 \times W_2) + (S_3 \times W_3) + (S_4 \times W_4) ). Calculate the total weight: ( \text{Total Weight} = W_1 + W_2 + W_3 + W_4 ). Finally, compute the weighted average as: ( \text{Weighted Average} = \frac{\text{Weighted Sum}}{\text{Total Weight}} ). This will yield the desired weighted average score.
To find the median of Wednesday's test scores, first arrange the scores in numerical order from least to greatest, then select the middle value as the median. If there is an even number of scores, the median is the average of the two middle values.
An average is worked out by dividing the total of the scores by the number of scores. You have 4 scores already so when you have done the next test it will be 5 scores. If you multiply 5 scores by 90 it gives you a total score of 450. The 4 scores you already have adds up to a total of 354. If you subtract 354 from the 450 you get 96 and that is your target for the final test. The average for the first 4 tests comes out at 88.5

The Library at Alexandria was the first comprehensive collection of works from around the world at that time, and was the first library available to those people not of aristrocracy.
