Answer : The mean score of Matthew's 7 geometry tests is, 84

Step-by-step explanation :

Mean : It is determine by adding all the numbers then divided by how many numbers there are.


Mean=\frac{\text{Sum of outcomes}}{\text{Number of outcomes}}

As we are given that the set of data:

82, 78, 81, 89, 79, 92, 87

Now we have to determine the mean.


Mean=\frac{\text{Sum of outcomes}}{\text{Number of outcomes}}

Sum of outcomes = 82 + 78 + 81 + 89 + 79 + 92 + 87 = 588


Mean=(588)/(7)=84

Therefore, the mean score of Matthew's 7 geometry tests is, 84
