Using the midpoint formula 
\frac{ x_{1}+ x_{2}  }{2},  
 \frac{ y_{1}+  y_{2}  }{2}
\frac{-3+7}{2},
 \frac{4+9}{2}
\frac{4}{2},
 \frac{13}{2}
(2,6.5)
So, your answer would be (2,6.5).

let t= 10  =1600

let t=11   =1936

let t = 12  =2304

Step-by-step explanation:

16t^2

let t=9

16(9)^2 = 16*81=1296

let t= 10

16 *10^2 = 16*100=1600

let t=11

Identify the percent increase in total sales and the percent increase in sales of trench coats. Then find which percent of
Ilya [14]

Answer:

Answer b: Sales of trench coats increased 8.3 percentage points faster than total coat sales.

Step-by-step explanation:

First add all the sales for 2006, and do the same for the 2007 sales, so we can compare both total sales numbers:

For 2006 we have:

103+297+210+213+137 = 960 total sales

For 2007 we have:

127+223+210+285+259 =  1104 total sales

The percent increase is calculated as the difference between the final value minus the original value, divided by the original value and multiplied by 100:

For the total number of coats we have that the percent increase is: \frac{1104-960}{960} * 100= 15%

For the trench coats (which went from 103 sales tp 127 sales) we have the following percent increase: \frac{127-103}{103} * 100= 23.3%

Therefore, the percent increase in trench coats was larger than the percent increase in total sales by:

23.3 % - 15% = 8.3%
