The low temperatures for one week at a ski resort were: -24, -15, -21, -32, -18, -9, & -14. What was the mean low temperature at the resort for the week?

-24 + (-15) + (-21) + (-32) + (-18) + (-9) + (-14) = -133
now divide by how many numbers there are
-133/7 = -19 <== the mean (average)

A gardener has 27 pansies and 36 daisies. he plants an equal number of each type of flower in each row. what is the greatest possible number of pansies in each row?

Answers

I just did this is our math book at school, but what you do is find the GCF of the numbers. So list all there factors. 27=1x27, 3x9, and that's it. 36=1x36, 2x18, 3x12, 4x9, and that's it. So, next you see that highest numbers they both have in common, in this case it is 9. So your answer is, 9 pansies.
