This is true since both legs are congruent, both medians are congruent
Answer:
Step-by-step explanation:
The theoretical result is 0.2 * 20 = 4
The experimental result is 1/2 * 20 = 10
The difference is 10 - 4 = 6
The probability difference = 6/20 = 0.3
I can't read that language but I'll guess it says write a second degree equation then solve for n when d=10.



Answer: n² - 3n - 20 = 0
That doesn't factor so there is no integer n solution.
That means there are no polygons with 10 diagonals.

Answer:
4n
Step-by-step explanation:
you multiply 4 x n= 4n
