Answer:
-8, 0, and -12
Step-by-step explanation:
Using -7 would get you 8. Using -5 would get you 4
Step-by-step explanation:
- You can use the distributive formula to answer:
a(b - c) = ab - ac
2(3x - 1) - 3x + 4
6x - 2 - 3x + 4
- Simplify by the common terms:
3x + 2
That is the answer
Hope that helped!!

Answer:
0.26 and 0.577
Step-by-step explanation:
Given :
x :___0 ___ 1 ____ 2 ____ 3
f(x):_0.80 _0.15__0.04 __0.01
The mean :
E(X) = Σ(x * p(x))
E(X) = (0*0.8) + (1*0.15) + (2*0.04) + (3*0.01)
E(X) = 0 + 0.15 + 0.08 + 0.03
E(X) = 0.26
Var(X) = Σx²*p(x)) - E(x)²
Σx²*p(x)) = (0^2*0.8) + (1^2*0.15) + (2^2*0.04) + (3^2*0.01) = 0.4
Σx²*p(x)) - E(x)² = 0.4 - 0.26² = 0.3324
Std(X) = √0.334 = 0.577
Answer:
Step-by-step explanation:
<u>Given is the geometric series, because the ratio of consecutive terms is common:</u>
The first term is 112.
<u>So the nth term is:</u>
<u>The 9th term is:</u>
