164.9
The mean is the average of all the numbers. To get this, you add all of the numbers together and divide the result by the amount of numbers.
Start by adding all of the numbers together to get 1,649.
Now, divide that by 10, since there are 10 numbers. This gives you a mean of 164.9.
Answer:
B?
Step-by-step explanation:
I think B should be checked as well. All angles of a rectangle and similar figures thereof should be 90°. Everything else looks good, but I will caution you that it's been a few years since geometry, so you definitely want to get some advice from others as well!
Hope this was some help!
Write 2 equations, multiply amount bought per month by number of months and add to the starting values :
Marko = 45 + 4M
Tamara = 61 + 2M
Set the equations equal to each other and solve for number of months:
45 + 4m = 61 + 2m
Subtract 45 from both sides:
4m = 16 + 2m
Subtract 2m from both sides:
2m = 16
Divide both sides by 2:
m = 8
Answer: 8 months
