X=Amount of skittles at the start.
Nasir ate 10 skittles and Seif ate 6 skittles so the number of skittles they had(x) - how many they both ate equals : 2/3;
(x-10)/(x-6)=2/3
3(x-10)=2(x-6)
3x-30=2x-12
x-30=-12
x=18
They each started with 18 skilttles.

The formula for the area of a parallelogram is bh.
15(h) = 300
h = 20
The height of the parallelogram is 20 yards.
2 tens, 4 ones, 3 tenths, 5 hundredths, 7 thousandths
Assuming a standard normal distribution, the positive value of interest will be that corresponding to the 50 + 36/2 = 68th percentile. A suitable probability calculator will give that value as 0.46770.
The values that are within ±0.46770 standard deviations from the mean will have a probability of 0.36.
