Answer:
Kaitlin's account will have 72% of the money initially invested, that is, about $ 6,192.
Step-by-step explanation:
Given that last year Kaitlin opened an investment account with $ 8,600, and at the end of the year, the amount in the account had decreased by 28%, to determine the year-end amount in terms of the original amount both in whole numbers and in decimals, the following calculation must be performed:
100 - 28 = 72
8,600 x 0.72 = X
6.192 = X
Thus, Kaitlin's account will have 72% of the money initially invested, that is, about $ 6,192.
6:11
If there are 6 used books and 11 total books, then there are 6 used books per 11 total books hence 6:11
The question asks us to find the mean absolute deviation ( MAD ). We know that the mean is 3. First we have to find the distance of the each value from the mean ( and ignore minus signs ). For example: 1 - 3 = | - 2 | = 2 ( absolute value ) etc. Then we have to find the mean of their distance: MAD = ( 2 + 2 + 1 + 1 + 0 + 0 + 0 + 1 + 2 + 3 ) / 10 = 12 : 10 = 1.2. Answer: The mean absolute deviation is <span>A ) 1.2.</span>
