Answer:
......
Step-by-step explanation:
Length of diagonal of the rectangle=
√( length) ²+( breadth) ²
=√(20) ²+(12) ²
=√400+144
√544 m
. '. Length of fence= √544 m
Perimeter of the triangle formed by the diagonal of the rectangle =(12+20+√544)
=(32+√544) m
N= numbers
x= x-ray
4 unknown number equal a unknown amount of x-rays mutiplyed but 5-unknow number.
x can stand for anything and so can n
Using the mean concept, it is found that:
- The mean return for Florida Company is 10%.
- The mean return for Minnesota Company is 12%.
The mean of a data-set is given by the <u>sum of all observations divided by the number of observations</u>.
For Florida Company(FC):
- 3 returns, of -5%, 15% and 20%.
Thus, the mean is:
The mean return for Florida Company is 10%.
For Minnesota Company(MC):
- 3 returns, of 8%, 8% and 20%.
Thus, the mean is:
The mean return for Minnesota Company is 12%.

Answer and Step-by-step explanation:
1. square and 20 ft because each side is 5 ft and 5+5+5+5=20
2. triangle and 25 ft because 12+5+8=25 ft
3. trapezoid but Im not sure what the side lengths are for that one so i dont know what the perimeter is
4. Parallelagram and the same as what happened with number three
5. hexagon and 8+8+8+8+8+8= 48 ft
