r² = 4
r = 2
This problem is mainly concerned with setting up an equation.
let's add the interest rates times their respective investment amounts:



simplify:

sum of interest:

1780 = (9000+x) 0.10 + x 0.06 + (11000-2x)0.08


solution:
He does not have any invested in the 6%, while he has 9000 invested at 10% and 11,000 invested at 8%
to check:


So this ended up being a trick problem because he does not actually have any invested in the 6% option.

<h3>What do you mean by Mean?</h3>
Aside from the mode and median, the mean is one of the measures of central tendency used in statistics. The average of the specified collection of numbers is what is referred to as the mean. It indicates a data set's values are distributed equally. The three most popular methods for determining central tendency are the mean, median, and mode. To find the mean, tally up all the values listed on a datasheet, then divide that total by the total number of values. When all the values are organised in ascending order, the median is the value that falls in the middle of the data. The number in the list that is repeated a maximum number of times is the mode, in contrast.
