The shape of cross section of a canal is a trapezium. if the canal is 10 m wide at the top and 6 m
wide at the bottom and the area of cross section is 72 sq. m, find its depth.

Solve the given system of equations. 2y= -x+9 , 3x-6= -15

Evaluate the function , when d = {9, 15, 30}. r = {5, 7, 12} r = {6, 10, 15} r = {6, 10, 20} r = {5, 12, 20}

Select the correct answer from each drop-down menu. james needs to clock a minimum of 9 hours per day at work. the data set records his daily work hours, which vary between 9 hours and 12 hours, for a certain number of days. {9, 9.5, 10, 10.5, 10.5, 11, 11, 11.5, 11.5, 11.5, 12, 12}. the median number of hours james worked is . the skew of the distribution is
