Final answer:

The average age of all the members at the yoga studio is 32 years.

Step-by-step explanation:

To find the average age of all the members at the yoga studio, we need to calculate the weighted average based on the proportions of men and women.

Given that 80% of the members are women and their average age is 30, and 20% of the members are men with an average age of 40, we can calculate the weighted average using the formula:

Weighted Average = (Proportion of Women * Average Age of Women) + (Proportion of Men * Average Age of Men)

Substituting the values, the weighted average age of all the members at the yoga studio is:

(0.80 * 30) + (0.20 * 40) = 24 + 8 = 32 years

Ok, so lets suppose there are 10 people there:

8 are women
2 are men

The average of the total is:


((30)(8) + (40)(2))/(10) = (320)/(10) = 32
