Answer:
Step-by-step explanation:
<u>Area of the trapezoid:</u>
<u>Substitute the base and height values:</u>
- A = 1/2(6 + 10)*2 = 16 ft²
<u>Total cost of lamination:</u>
15ft because 12x.25=3 so 3ft is 25% of the 12ft, add the 3+12=15
1. I think A is 5 because it is the lower quartile range
2. The median of the data is 56 because the median of a plot is in the middle of the data
3. The greatest value of the data plot is 45 because it is higher than the rest of the numbers (upper quartile range).
4. The median of the plot is 41 because if you look at the box-whisker plot you can see that it is in the middle of the box
5. Your answer would be 42 because on a box-whisker plot, the first quartile is on the side of the box(first quartile).
Hope this helps :)

Answer:
- $10,000 in the 11% fund
- $5,000 in the stock
Step-by-step explanation:
Let f and s represent the amounts invested in the fund and in stocks, respectively. The problem statement gives rise to two equations:
f + s = 15000 . . . . . . . Susan invested a total of 15000
0.11f + (-0.05)s = 850 . . . . . her total return was 850
These can be solved by any of a variety of methods. Using elimination, we can multiply the second equation by 20 and add it to the first:
20(0.11f -0.05s) +(f + s) = 20(850) +15000
3.2f = 32000 . . . . . . . . . simplify
f = 10000
s = 15000 -f = 5000
Susan invested $10,000 in the fund and $5,000 in stock.
