Answer:
9413
Step-by-step explanation:
Given that :
Error = $2 ; Standard deviation (σ) =99 ; α = 95% = 0.95
Zα/2 = Z0. 05/2 = 1.96 (Z probability calculator)...
n = sample size
Recall:
n = ((Zα/2 * σ) / Error)^2
Using the formular above, the sample size n can be obtained ;
n = ((1.96 * 99) / 2)^2
n = 97.02^2
n = 9412.8804
n = 9413
Combine like terms to get 2y2-2y+4x
24.48 / 24 = 1.02
24.97/24.48 = 1.02
25.47 / 24.97 = 1.02
Common ratio - 1.02
Answer:
x=1
Step-by-step explanation:
-2x+4=1-4x-3
↦-2x+4x=1-3+4
↦2x=2
↦x=2/2
↦x=1
.°. x = 1
