So it ask to find the average with is ur mean....to find your mean u add everything up and divide it by the total amount...so basically 5×8.094= 40.47 and then u add up ur total 33.23 then take 40.47 - 33.23 = answer
The total area under the curve must equal 1. Let the value of the density curve be x. Then 10x = 1. Therefore x = 1/10 or 0.1. The correct answer is D. 0.1.
