Case 1: Probabilities cannot add up to a number greater (or less) than 1. This would mean there is greater than a 100% chance of something happening which just doesn't make sense. 0.4 + 0.4 + 0.3 = 1,1
Case 2: You cannot have a negative probability. That is claiming that there is a -10% chance of an event happening, there is at the very least a 0%. Despite them "adding" up to 1, the negative probability makes no sense.
Hope I helped!
Im pretty sure it would be 54÷ b- 6 if your looking for only the cost of the braclets nothing else.
Answer:
in graph A the vertex is (0,0)
in graph B the vertex is (0,3)
in graph C the vertex is (0,-3)
And in graph D the vertex is (0,-1)
The axis of symmetry for all of the is 0
And i don't remember maximum and minimum sorry
For the base of the shape all you need to do is multiply 25x25=625ft²
then for the 4 sides you need to multiply 25x32=800ft²
and because there are 4 sides you multiply 800x4=3200
so now you add 3200 with 625 (3825) and there's your area
Letter B I have done this before
