Emily earned $166 more in her account than Katie.
We use the compound interest formula for both of these:

For Katie's deposit:

This gives Katie 6083.26-5000 = 1083.26 in interest (1083, to the nearest dollar).
For Emily's deposit:

This means she earned 11248.64-10000=1248.64 in interest (1249, to the nearest dollar).
The difference in interest is given by 1249-1083=166
Answer:
8 = x
or
x = 8
Step-by-step explanation:
x – 3 = 5
x + -3 + 3 = 5 + 3
x = 5 + 3
(5 + 3 = 8)
x = 8
Answer: $26
Step-by-step explanation:
Since the 7 tickets cost $168, the value of each ticket will then be:
= $168/7
= $24
Each ticket cost $24
If one friend gave him $50, the change that the friend will collect will be:
= $50 - $24
= $26
Therefore, Edward should return $26 to the person.
A median is 65 inches and a standard deviation is 1.7:
a. 65 + 1 SD = 65 + 1.7 = 66.7 in
It means that there are : 100% - ( 50% + 34% ) = 100% - 84% = 16% students taller than 66.7 inches.
b. Heights between 61.6 in and 68.7 in are within 2 standard deviations:
13.5% + 34% + 13.5% + 34% = 95%
0.95 * 300 = 285
There are 285 students between 61.6 in and 68.7 in tall.
