Answer:
B
Step-by-step explanation:
Well, 3.7 is the same as 3 7\100 so as an improper fraction, it is 307/100 and then you multiply it by 2, top and bottom. there is your answere
Its 11/12 , you need to divide the "wanted results" (every dog which is either black, with spots or both ) by every every possible result ( all dogs ). so 11/12=0.92
In scientific notation it would just be 3.06 x 0, it is the same thing as the regular notation.
