Let's say that the value invested in the account with a rate of 8% is "x", then the amount invested in the account with a rate of 12% is:
To calculate the total interest we need to calculate the interest of each individual account and sum them:
The total interest is the sum of the two expressions above:
The value invested in the account with 8% interest is 830, the one invested in the account with 12% interest is 1280.
Answer:
Mean =25.78
Median =20
Step-by-step explanation:
given that the following list contains the average annual total returns (in percentage points) for 9 mutual funds. The mutual funds appear in an online brokerage firm's "all-star" list.
40, 30, 6, 10, 30, 18, 15, 20, 36
Let us find the sum of these 9 entries
Sum = 205
a) Mean =
b) Median of this data set is the middle entry after arranging in ascending order
Here it would be the 5th entry
6,10, 15, 18,20, 30, 30, 36, 40
Median = 20
