The following is a list od the heights of students in Molt's class in inches.
67, 68, 61, 69, 63, 71, 68, 71, 67, 74, 65, 73, 71, 72 and 65

What is the interquartile range of the heights

If f(x)=2x+2and g(x)=x^3, what is (g•f)(2)

Type the correct answer in each box. spell all words correctly. a sequence of transformations maps ∆abc onto ∆a″b″c″. the type of transformation that maps ∆abc onto ∆a′b′c′ is a . when ∆a′b′c′ is reflected across the line x = -2 to form ∆a″b″c″, vertex of ∆a″b″c″ will have the same coordinates as b′.

Solve this 364x-64x=300x and 12(x2–x–1)+13(x2–x–1)=25(x2–x–1)
