Step-by-step explanation:
The number of steel rods for 95% confidence level


E=3

Substituting values


Thus 97 rods is tested
OK...... your answer would be
- 10y^2 - 26y + 1/y

Sh(2x) = (e^2x + e^-2x)/2
<span>Thus the integral becomes </span>
<span>Int[e^3x*(e^2x + e^-2x)/2] = Int[(e^5x + e^x)/2] </span>
<span>= e^5x/10 + e^x/2 + C
</span>=(1/10)(e^5x) + (1/2)(e^x) + C
