Answer:
20
Step-by-step explanation:
Assume n is the number of times she pick a skittle out of the bag
The probability she pick out red : 8/n
The probability she pick out yellow : 12/n
=> The ratio of red and yellow skittle : 8/n : 12/n = 8/12 = 2/3, means every 2 red skittles we have 3 yellow ones.
But we have 50 skittles, so the likely numbers of reds in the bag is = 2* = 20
(-5,-3)=1
(-5.2)=2
(2,-3)=3
(2,2)=4
From 1 to 2 and 3 to 4 it is 5. From 2 to 3 and 1 to 4 it is 7. So, you have a square that is 7 by 5 by 7 by 5. Perimeter is 24. Area is 35.
