Let x is average for rest of seven test. Then average for remaining test is x= 2.27
The middle number, which is obtained by dividing the sum of all the numbers by the variety of numbers, is the average value in a set of numbers. To calculate the average of a set of data, add up all the values and divide the result by the total number of values.
The middle point of the set of values is the mean. It represents the mean of the data set's values. In statistics, the centre number, also known as the mean, is referred to as the average.
We want the TOTAL average to equal 94
4/9 of the 5 scores have an average of 178
Let x = average of the 5 remaining test, which is worth 5/9 of the total average.
We get: 94 = (4/9)(178) + (5/59)(x)
94=712/9+59x/9
846=712+59x
846-712=59x
134=59x
134/59=x
Solve: x = 2.27
