The mean is the average.
i’ve found this a helpful way to remember:
the medians the middle
the mean old average
481,000
this is the answer because standered form is just asking to write the number out instead of notation
The sum of their ages equals 80.
Gabrielle is 3 times older than Mikhail
Two numbers that have a sum of 80, with one number being 3 times the other are:
Gabrielle’s age: 60
Mikhail’s age: 20
60 + 20 = 80
20 x 3 = 60
Mikhail is 20 years old.
