Gabrielle's age is three times Mikhail's age. The sum of their ages is 92. What is Mikhail's age?

Gabrielle is 69 while Mikhail is 23.

Step-by-step explanation:

Let G represent Gabrielle's age and M represent Mikhail's age.

Gabrielle is three times Mikhail's age. In other words:

The sum of their ages is 92. In other words:

This is a system of equations. Solve. Substitute in G:

Thus, Mikhail is 23. Now, find Gabrielle's age:

Gabrielle is 69.

an advantage of the standard deviation is that it increases as the dispersion of the data increases. e. the interquartile range is preferred when the data are not skewed or no have outliers. an advantage of the standard deviation is that it uses all the observations in its computation.
