Zack has two savings accounts with the total of $9,000. he withdew 10 percent from one and 60 percent from the other to buy his girlfriend an engagement ring. if the ring cost$2,175, find the remaining balance in each account.

The remaining balances in the first and second account are $5805 and $1020 respectively.

Explanation

Suppose, the initial balance in the first account was   dollar.

As the total amount in two accounts was $9000, so the initial balance in the second account was  

He withdrew 10% from the first and 60% from the second account to buy the ring which cost $2175. So, the equation will be......

So, the initial balance in the first account was $6450 and in the second account was ($9000 - $6450)= $2550

Thus, the remaining balance in the first account = 90% of $6450 =

and the remaining balance in the second account = 40% of $2550 =

see below

step-by-step explanation:

7.   there are 10 data points in the set.   the middle point is between 5 and 6.   the middle point in the top half is 8   and the middle point in the bottom half is 3. to find the iqr , take point 8 and subtract point 3

mid term   point 8 = 100   point 3 = 88

iqr = 100-88 = 12

final   point 8 = 93   point 3 = 78

iqr = 93 - 78 = 15

the final has the greatest iqr

6.   b - there is a high data value that causes the data set to be asymmetrical for the males: the data for males are high and asymmetrical .   there is an outlier for the males that skews the data

5.   the   iqr is a better measure of spread for the movies and basketball games.   since the basketball game has an outlier, we do not want to use standard deviation for measurement.  

3.   the exam median is much higher than the class median.   the median line is farther to the right on the exams

2.   there is no way to tell what the means are from the box and whisker plots.
