5/12 is the simplest form that it can be simplified to.
Answer:
Let the Dulcina's collection be 'x'
Let the Tremaine collection be 'x-39'
x + x - 39 =129
2x = 129 +39
2x = 168
x = 168/2
x = 84
Dulcina's collection = x = 84
Tremaine's collection = x - 39 = 84 - 39 = 45
3 is no cuz obtuse angle is >90 degrees, all the angles together must equal 180 degrees, and if you try it, you get no. 5 is 25% of 45, which is $11.25.
Based on this sample, 100 toys will not meet standards.
There is 1 value that is 75 or lower in this simulation. This makes the experimental probability 1/10. 1/10(1000) = 100 toys for the month.
