Answer:
10 years
Step-by-step explanation:
the average or mean value is the sum of all data points divided by the number of data points.
x = the unknown age of the 5th student.
average = 9 = (5 + 7 + 8 + 15 + x)/5
45 = 5 + 7 + 8 + 15 + x = 35 + x
x = 45 - 35 = 10
the 5th student is 10 years old.
500,000,000 and 2,000,000
10 exponent 8 is 100000000 because it has 8 0s
multiply that by 5 to get 500,000,000
10 exponent 6 is 1000000 because it has 6 0s
multiply by 2 to get 2,000,000
