Answer:
1/28
Step-by-step explanation:
Before picking 1st song
Total songs = 8
Rock songs = 2
Probability of picking a rock song as the first song,
= 2 rock songs out of 8 total songs remaining
= 2/8
After picking 1st song
Total songs left over = 7
Rock songs left over = 1
Hence, Probability of picking a rock song as the second song,
= 1 rock song out of 7 total songs remaining
= 1/7
Probability of picking 2 consecutive rock songs,
=
x 
= 
10
The x’s represent just the people, and because the bottom line only represents time it doesn’t affect the amount of people.
I would say a but not 100% sure.
f(x)=2x^3+2x^2-4x
The zeros of polynomial functions
2x^3 + 2x^2 - 4x = 0
2x(x^2 + x - 2) = 0
2x(x - 1)(x + 2) = 0
2x = 0; x = 0
x - 1 = 0; x = 1
x + 2 = 0; x = -2
Answer
x = -2 , 0 , 1
