Find the average of the third grade of primary school. X (with a horizontal line above) =(95+92+93)/3=280/3.
How to get the average score of 95.92.93 in the third grade of primary school? The problem is wrong. There can't be such a problem.
What is the average of 95, 87, 100, 92, 96 in the third grade of primary school? Average is to add several numbers and divide the sum by the number of terms.
The average of these figures you gave is:
(95 + 87 + 100 + 92 + 96)/ 5
= 94
How to calculate the average value? Add up all the numbers with the technique of the second volume of the third grade of primary school (assuming that a * * * has n numbers, this n is just a tool to tell you, and you don't need to write it out). Divide the sum they get by n and you get their average.
There are three numbers abc; The average value of ab is15; The average bc is19; The average value of ac is17; What are these three numbers? Use the method of the third grade of primary school 15×2=30.
19×2=38
17×2=34
(30+38+34)÷2=5 1
C:5 1-30=2 1
B:5 1-34= 17
A: 5 1-38= 13.
In the third grade of primary school mathematics, the average of five numbers is 8, the average of the first three numbers is 6, and the average of the last three numbers is 9. What is the third number? The sum of the first three numbers and the last three numbers =6*3+3*9=3* 15=45 5 The sum of five numbers =5*8=40 45, and the extra five numbers are the third number.
The average of a and b is 15 b, and the average of c is 17. What's a, b and c? The answers are A = 14, B = 16 and C = 18. In the process of solving the problem, the conditions in the third grade of primary school are insufficient and the solution is not unique. B is 10, A is 20 and C is 24, which is also a solution.
The first two conditions both have B, so if B is an arbitrary number, both A and C can be solved.
There should be condition a.
