Answer:
X=3
Step-by-step explanation:
2(4x−3)−8=4+2x
2)(4x)+(2)(−3)+−8=4+2x
8x+−6+−8=4+2x
8x−14=2x+4
8x−14−2x=2x+4−2x
6x−14=4
6x−14+14=4+14
6x=18
x=3
Answer:
0.195
Step-by-step explanation:
Given:
For ; sample size, n = 9 ;
Standard Error (S. E) = 0.39
S. E = σ / sqrt(n)
σ = standard deviation
0.39 = σ / sqrt(9)
σ = 0.39 * 3
σ = 1.17
Therefore, For n = 36
S. E = 1.17 / sqrt(36)
S.E = 1.17 / 6
S.E = 0.195
Answer:
4^-5
Step-by-step explanation:
4^-3 = 1/4^3
1/4^3 · 1/^2 = 1/4^5 which is the same as 4^-5
