Answer:
Step-by-step explanation:
Find the rows in the table where f(x) shows the same value as g(x). Those rows are ...
x = -1, f(x) = 1, g(x) = 1
x = 1, f(x) = -7, g(x) = -7
The values of x are what is of interest. They are -1 and 1.
Total number of beads = 3 + 8 + 7 = 18. P(red) = total number of red/total number of beads = 3/18 = 1/6. P(blue) = total number of blue beads/total number of beads left after replacement = 8/17. P(black) = total number of black beads/total number of beads left after replacement = 7/16. Therefore P(red) = 1/6. P(blue) = 8/17. P(black) = 7/16.
If you have any more questions let me know!
I got 50.24
since 2*3.14*8=50.24
but if you want it rounded to the nearest tenth I guess it would be 50.2
Hope this helps :)
