The answer is 68.67.To find the average, you add the numbers together and divide by how many numbers there are. In this case, you would add the numbers together and divide by 3.64 + 69 + 73 = 206206 / 3 = 68.67
-- To average 70 on four tests, the total of the scores has to be 280 .-- You already have (64 + 69 + 73) = 206 on the first three tests.-- You need (280 - 206) = 74 on the fourth one in order to average 70 on all four.You can do it !Is that kind of what you were asking ?
There are 14 numbers - therefore, the median number is halfway between the seventh and eighth number. This is therefore 70.5.
It is: 64+9 = 73
71.085106
The average of 64, 69, 73 and 74 is 70.The average of 64.69 and 73.74 gives 69.215 as the result.
Because 64 + 69 + 73 is a single number, 206, it's average is 206. If on the other hand, you actually mean to ask "What is the average of 64, 69 and 73?" then the answer is 206 / 3 = 68 2/3
68.66 recurring is the average.

The answer is 74 To find the answer to this problem, you use this equation: (64 + 69 +73 + x) / 4 = 70 (206 + x) / 4 = 70 x = 74
64 - 69 - 73 - 77 - 81 - 85 = -321 if carried out from left to right. Subtraction is not an associative operation if the question was about any other expression then more information is required.
Andrew needs to earn an average score of 70 over all four tests. To achieve this, since his average from the first three tests is 69, he must score 71 on the final exam (70 * 4 - 64 - 69 - 73 = 71).
There are 14 numbers - therefore, the median number is halfway between the seventh and eighth number. This is therefore 70.5.
73 and one third
69+73=142
69 out of 73 equates to 94.52%
