Answer:
If you are just looking for a simplified answer then the answer is -7x - 3.
I guess you are asking to find the sum of the first 8 terms. If so, then:
Sum = a₁(1-rⁿ)/(1-r), where a₁ is the 1st term, r=common ratio and n=number of terms:
the 1st term a₁ =3
common ratio r = - 2 (since -6/3 = - 2, and 12/-6 = - 2, etc.)
Sum = 3[(1- (-2)⁸]/(1-2) = 3(1- 256)/(1/2)
Sum = -1530
Answer:
0.30
Step-by-step explanation:
P(x ≤ -3) = P(x=-3) + P(x=-5)
P(x ≤ -3) = 0.13 + 0.17
P(x ≤ -3) = 0.30
