Answer:
Step-by-step explanation:
B yes their slopes are negative reciprocals
When you roll two numbers you have four kinds of outcomes: EE, EO, OE, OO (where E = even, O = odd).
You get an even sum only if you sum two numbers that are both even or both odd, therefore the outcomes wanted are two: EE and OO.
Therefore:
P(sum is even) = 2 / 4 = 0.5
Hence, there is a 50% probability that, when you roll two numbers, their sum will be even.
These matrices ARE inverses of each other!
Answer: It would be I, the 4th one.
Step-by-step explanation:The 2 squares on the outside would fold up, that would leave the top and the 2 opposite sides left, so you would fold the other 3 squares on the bottom over the top, till it would cover all the other exposed sides.
Hopefully this makes sense!
