The mean age of 9 women in an office is 27 years old. The mean age of 7 men in an office is 25 years old. What is the mean age (
marta [7]

Answer:

26 years

Step-by-step explanation:

Given:

The mean age of 9 women = 27 years old

The mean age of 7 men = 25 years old

Question asked:

What is the mean age (nearest year) of all the people in the office?

solution:

By using, mean = sum of observations divided by number of entities

The mean age of 9 women = 27 years old

\frac{sum of ages}{number of women} = 27

Sum  of ages of women = 27 \times9 = 243\\ years

The mean age of 7 men = 25 years old

\frac{sum of ages}{number of men} = 25

sum of ages of men = 25 \times7 = 175

Total sum of ages of men and women in the office = 243 + 175

                                                                                     = 418 years

Total number of people in the office = 9 women + 7 men = 16

The mean age of all the people in the office = Total sum of ages of men and women in the office divided by Total number of people in the office

                                                                         = \frac{418}{16}  = 26.125

Therefore,  the mean age (nearest year) of all the people in the office = 26 years

The area of a patio is 72 square feet. The length of the patio is 1 foot longer than the width. What is the width of the patio?
mote1985 [20]
I know there must be an equation to do this, but there is a simpler way.
Just factor number 72 into two numbers which, when multiplied, equal 72. Two of such numbers are 9 and 8, and you can see that the difference between those two numbers is just 1. So that is the answer to your question - the length of the patio is 9 feet, whereas the width is 8 feet.
