the same vocabulary test with 50 questions is given to 600 students from 5th to 10th grade and the number of correct responses is collected for each student in this group. the interquartile range is 40 correct responses. what does the IQR tell you about the data?

You drop a rubber ball off the roof of a 50 meter high building onto a paved parking lot. it bounces back up with every bounce, but not quite all the way back up to you. after the first bounce it bounces back only 80 percent of the distance it was dropped from. the pattern continues, meaning after every bounce it comes up to just 80 percent of the previous maximum height. so if before the first bounce the height is 50 meters, what height does the ball reach after the fifth bounce? round your answer to one decimal place and chose the correct response from the choices below:

X-intercept=-5 y-intercept=2 the equation of the line is

If square root x = -7, then x= -49 true or false
