All you need to do for this is remove the parenthese and your answer will be
because that's the furthest it can be simplified.
Since 120 students gained less than 70, and 70 is the upper quartile, 120 people are in the 75% of all the students so we need to find the total number of students.
we need to multiply 0.75 (75%) by something to get 120. which is 160 (the total number of all students).
and since 48 is the median score, find 50% of 160 which is 80!
hope this helps :)
Answer:
Step-by-step explanation:
7x - 9 = x + 3
6x - 9 = 3
6x = 12
x = 2
7(2) - 9 + 2 + 3
14 - 9 + 5
5 + 5 = 10
Based on the types of compounding and the interest rates, the following are true:
- Part A - The group will have $750
- Part B - The group will have $759.19
When using simple interest, the amount the group will have is:
<em>= Amount x ( 1 + rate x number of years )</em>
= 600 x ( 1 + 5% x 5)
= $750
When using compound interest, the group will have:
<em>= Amount x ( 1 + rate) ^ Number of years</em>
= 600 x ( 1 + 4%)⁶
= $759.19
In conclusion, compound interest yields more.
