- I need the correct answer and as soon as possible pleaseI need the answer as soon as possibleA manufacturer of small appliances purchases plastic handles for coffeepots from an outside vendor. If a handle is cracked, it is considered defective and must be discarded. A large shipment of plastic handles is received. The proportion of defective handles p is of interest. How many handles from the shipment should be inspected to estimate p to within 0.09 with 95% confidence? (Round your answer up to the nearest whole number.) USE SALT handles

How will the test data look like in a graphical form? Select all those are correct. The line will show the pick hump. The line slopes 45 degree. The line is parallel to the zero-demand line. The breakpoint will be clearly visible in the graph.Assuming that the specific gravity of the following substances is approximately the same, that is, 2.65, and that the water is at 20°C, calculate the time it will take to settle 1m of the following materials: a) Gravel (Dp=10,000 μm) in seconds I want help with this one, I did the problem but the time gave me 36.36 seconds and the Dr told me that the result is incorrect, I would like to know how to do it. I used the formula of V=Dp^2(g)(△p) / 18μ ; Then use a substitution to calculate the time which would be t=h/v
