The given expression "2 divided by the quantity of 2 plus 5i" can be translated as 2/(2+5i). Simplifying expressions aim is to simplify it into its simplest form. Since i = √-1 substitute it into the expression.

2/(2+5√-1)
then multiply it by 2-5√-1 on the numerator and denominator and we have 
[2(2 - 5√-1)] / [4 - 25(1)]
(4-10√-1)/(-21)

22*60=1,320

So currently we are at a profit of $120.

120-6=114


Total profit: $114

1.) <span>It typically takes teachers 9 minutes longer than students to get ready for school. - The median of two data = Teachers 25 - Students 16: typically, teachers take 25 mins to get ready and students take 16 mins to get ready.

2.) </span><span>Both of the means are correct, but the reasoning is incorrect. - the mean absolute deviation for team A is 2 and for team B is 0.8. Greater mean does not signify higher mean absolute deviation.

3.) </span><span>The students tend to have fewer siblings than the teachers. - the teachers have a wide range of data and they have more siblings than the students so the first choice is the better option.

4.) </span><span>between 120 and 153 mph in race A; between 125 and 145 mph in race B - get the data from the lower whisker till the median.</span>
