Step 1 :Given that \(p_1 = 0.21\) and \(p_2 = 0.20\), we need to solve for \(N\) in the equation \(\mid 0 Step 2 :First, we can remove the absolute value by squaring both sides of the equation. Step 3 :Then, we can multiply both sides by \(N\) to get rid of the division. Step 4 :After that, we can square root both sides to get rid of the square root. Step 5 :Finally, we can solve for \(N\) by dividing both sides by the coefficient of \(N\). Step 6 :The solution to the equation is approximately 1.729. This is the value of \(N\) that satisfies the given equation with \(p_1 = 0.21\) and \(p_2 = 0.20\). Step 7 :Final Answer: The solution to the equation is \(\boxed{1.729}\).
