WHY SHOULD YOU PAY CREDIT CARD BILLS IN FULL?
To avoid paying interest.
WHAT ARE TWO MEASURES OF CENTER, AND HOW DO YOU SOLVE FOR THEM?

7

ORDER THE FOLLOWING TEMPERATURES FROM COLDEST TO WARMEST.
3/4 ...... -1/2 ..... -1.02..... -1.3 ...... 2/5
-1.3 .... -1.02 .... -1/2 ..... 3/5 ....3/4
NAME ONE WAY TO BUILD CREDIT HISTORY.
By taking out a small loan and paying it back, or by getting a credit card and paying full each month.
BOTH HAVE A MEDIAN OF 17. WITHOUT CALCULATION, DESCRIBE HOW THE MEAN OF B IS DIFFERENT FROM MEAN OF A. (BE SPECIFIC.)
A. 15, 16, 17, 18, 19, 20
B. 01, 16, 17, 18, 19
Both have nearly the same values, but B has a small outlier smaller than other numbers - this means the sum of all values in B is smaller than all values of A.
Mean of B is less than the mean of A because mean is affected by the sum.
DESCRIBE HOW TO CONVER 6/15 TO PERCENT. (DON'T NEED TO DO CALCULATIONS.)
Fraction to decimal ("man on horse"), then decimal to percent (decimal twice to right).
NAME ALL PROPERTIES THAT APPLY BELOW. HOW DO THEY APPLY?
9 - 4x3 --> 3x4 - 9
9 - 4(3) --> 3(4) - 9
Commutative property of multiplication applies when 3x4 are switched; however, the switching around the subtraction symbol is not valid. Can only do that with addition and multiplication.
OTHER THAN WORKING AND GETTING A LOAN, NAME THREE WAYS YOU CAN PAY FOR COLLEGE.
