Answer 1

John Douglas's average grade is calculated by summing his two grades (84 and 98) and then dividing by the number of grades, which results in an average of 91.

Step-by-step explanation:

To calculate the average grade of John Douglas, we need to sum the grades and then divide by the total number of grades. He has two grades: 84 and 98. The sum of these grades is 84 + 98 = 182. Since there are two grades, we divide the total by 2 to find the average.

Average grade = Total sum of grades / Number of grades
Average grade = 182 / 2
Average grade = 91

Therefore, the average grade for John Douglas is 91.
