to gather data for a statistics project, a student asked 10 friends how many hours of sleep they got on the previous night. The data are shown in the following list. 7 6 5 9 3 4 7 9 5 8 What is the interquartile range (IQR IQR ) of the number of hours of sleep shown in the list?

Which of these statements is correct? the system of linear equations 6x - 5y = 8 and 12x - 10y = 16 has no solution. the system of linear equations 7x + 2y = 6 and 14x + 4y = 16 has an infinite number of solutions. the system of linear equations 8x - 3y = 10 and 16x - 6y = 22 has no solution. the system of linear equations 9x + 6y = 14 and 18x + 12y = 26 has an infinite number of solutions.
