The following are the ages (years) of 5 people in a room:
13, 22, 13, 18, 14
A person enters the room.
The mean age of the 6 people is now 23.
What is the age of the person who entered the room?

58

Step-by-step explanation:

the mean is adding up all the numbers, then dividing by the amount of the numbers.

add up all the numbers:

13 + 13 + 14 + 18 + 22 = 80

the mean is 23.

so you need to back track:

23 * 6 = 138

138 - 80 = 58

the camry sales+accord sale=828,000. to make it so the two numbers are 18 thousand apart and still equal 828,000, you first need to find out what half of 828,000 is. 828,000/2=414,000. for the two numbers to equal 828,000, you have to add the same amount as you subtract from the middle. in this case, the number is 9,000 because it's half of 18,000. to equal 828,000, you have to add 9,000 to 414,000 for the camry and subtract 9,000 from 414,000 for the accord. 414,000+9,000=423,000.

414,000-9,000=405,000.

423,000+405,000=828,000.

423,000-405,000=18,

hope it

5050 i think
