Answer:
$595.34
Step-by-step explanation:
Step one
given data
interest rate of 2.5%= 0.025
final amount= $690
time = 6 years
Required
Principal P
Step two
The compound interest formula is
substitute
divide both sides by 1.159
P=690/1.159
P= $595.34
Consider the set {4, 5, 7, 8, 8, 12, 13, 13, 15, 18, 20, 22, 24, 26, 27, 37, 38}. if you were dividing the set into intervals, w

Answer:
C) 4-12
Step-by-step explanation:
<u>A) 0-7</u>
<em>Its frequency will only be 3 and there are no numbers from 0 till 3 therefore, this is not the best interval.</em>
<u>B) 4-5</u>
<em>This interval is too short. If you go on with the intervals, there will be a lot of sets. Therefore, this is not right.</em>
<u>C) 4-12</u>
<em>The set starts from 4 and so does the interval. The interval 4-12 will have a frequency of 6 and the next intervals will be 13-21, 22-30, 31-39.</em>
<em>Therefore, this is the best interval for the data.</em>
<u>D) 0-10</u>
<em>There are no numbers from 0-3 or 9-10, therefore this is not the best interval.</em>
The correct answer is option C) 4-12

Answer:
7 days
Step-by-step explanation:
So! Ms. Masi earns $11.25 everyday, and is paying her brother back everyday. Let's make an equation to solve for the number of days!
11.25d = 72 <em>(d = # of days)</em>
<em>Now, we have to solve this equation to see how many days (d) it will take Ms. Masi to pay her brother back.</em>
<em></em>
11.25d = 72
÷11.25 ÷11.25 (Divide by "11.25" to get the variable by itself)
d = 6.4
<em>Since, she only gets 1 pay per day, Ms. Masi will have to wait til her 7th day to pay her brother back.</em>
