Housefles have preety short lifespans. males of certain species have lifespans that are strpngly skewed to th eright with a mean of 26 days and a standard deviation of 12 days. A biologist collect a random sample of 10 of those male houseflies and repeats the asmplig for 50 times to calculate the sample mean lifespan. We can assume that the houseflies in each sample are independent. What will be the shape of the sampling distribution of the sample mean lifespan ? normal , skewed left , unknown or skewed right ?

Me! i'm really confused the isosceles trapezoids, abcd and efgh, are similar quadrilaterals. the scale factor between the trapezoids is 2: 3, line gh = 6 centimeters, line ad = 8 centimeters, and line ab is three times the length of line dc . use complete sentences to answer the following prompts and include all of your calculations in your final answer. a. write a similarity statement for each of the four pair of corresponding sides. b. write a congruence statement for each of the four pair of corresponding angles. c. determine the perimeter for each of the isosceles trapezoids.
