(81 + 77 + 83 + 75 + X) divided by 5 = 80 average
316 + X = 400
X = 84
First of all, Euclid was from Athens, not from Alexandria. Second, he learned in Athens and he went to the Library at Alexandria to teach.Where can i find the source of this information?
Average of three test scores is 84 can be written (x+y+z)/3=84. If you know two of the scores then (79+93+z)/3=84, so to solve for z, 79+93+z=84*3 z=252-79-93 z=80 The first test score was 80
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).
(55+85+58+77) / 4 = 69
The lowest 25% of values.
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

Since the first recorded rudimentary steam engine being the AEOLIPILE described by Hero of Alexandria from Alexandria Egypt.
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.
Average of three test scores is 84 can be written (x+y+z)/3=84. If you know two of the scores then (79+93+z)/3=84, so to solve for z, 79+93+z=84*3 z=252-79-93 z=80 The first test score was 80
step 1: add all four scores 132 + 140 + 145 + 128 = 545 step 2: divide the total points of the four scores by the number of scores 545 divided by 4 = 136.25 136.25 is the average. The key to finding an average is to add all numbers together. Then dividing the answer by how how many sets of numbers there were to add. Example: Find the average of Cindy's test scores 75, 87, 72, 95, and 68. first add them together: 75 + 87 + 72 + 95 + 68 = 397 now divide the total by how many items there are: 397 divided by 5 = 79.4
