Answer:
385
Step-by-step explanation:
Given that :
Mean, m = 500
Standard deviation, s = 100
Zcritical at 95% = 1.96
Confidence interval, C2 - C1 ; 510 - 490
Using the relation :
n = (2 * Zcritical * s) / (C2 - C1)
n = sample size
n = [(2 * 1.96 * 100) / (510 - 490)]^2
n = (392 / 20)^2
n = 19.6²
n = 384.16
n = 385

Answer:
The proof is below.
Step-by-step explanation:
Given two triangles similar.
we have to prove that ratio 
As, △OKE∼△VDE
∴ their corresponding sides are in same proportion.

⇒ 
⇒ [tex}\frac{EK}{EO}=\frac{VE}{ED}[/tex]
Hence Proved.
