Answer:
1/5
Step-by-step explanation:
You expect to get 12 red marbles out of 60 trials.
So, you expect to get a red marbles 12/60 of the times.
We can simplify that 12/60 to 1/5, which is a choice of answers. :-)
We assume here you correctly assume your probability level when you did your forecast of 12/60. And either you're picking from a small pool and re-insert the marble, or you have a very large amount of marbles (at least 60).
Find two factors of the last number that add up to the middle number.
a) two factors of 16 that add to 10: 8 and 2. Because 8x2=16 and 8+2=10. then do this:
(x+8)(x+2)
b) (x+4)(x+3)
c) (x+12)(x+1)
Answer:
Step-by-step explanation:
find the difference between two percentages,Example, it's 15% - 5% = 10%. Second: Take 10 percent, and divide by 2nd percentage: 10/5 = 2. Now multiply this number by 100: 2*100 = 200%
