I think that the answer would be B
An=Asub1(r)n-¹
=5(-2)7-¹
=5(64)
A7=320
For this equation, you simply plug in the number 5 every time you see an n. So T(5)=5-7, which equals -2
51 + 30 + 69 = 150 total
probability purchased grape flavor = 30/150 = 0.2
answer
A. 0.2
Answer:
1
Step-by-step explanation:
2x^2 + x -1 = 2
2x^2 + x-1-2 = 0
2x^2 + x -3 = 0
2x^2 -2x + 3x-3 = 0
2x(x-1) + 3(x-1) = 0
(2x + 3)(x-1) = 0
2x + 3 = 0
or x-1 = 0
x = -3/2 or 1
