A survey made on 45 students for number of hours spent on watching TV in a week is recorded 8,4,7,10,12,15,10,9,8,7,12,14,16,5, 6,13,8,7,9,14,10,15,12,6,15,12,7,6, 9,10,6,15,14,10,4,9,8,10,7,4,8,7,13 ,6,18.
arrange the above data in ascending order:
(¡) how many students watch t. v for more then 15 hours a week
(¡¡) how many of them spend less then 6 hours a week on t. v

The graph shown is the graph of which function?

In the following diagram it is given that dec,ab || dc, ad || eb, and ad is congruent to bc. a)why isn't abc a parallelogram even though it has a pair of parallel sides and a pair of congruent sides b)explain why be must be congruent to bc. further explain what type of triangle this makes triangle abc and what it tells you about angle 1 and angle 2c) finally why must angle 3 be congruent to angle 1? further, explain why we know that angle 3 is congruent to angle 2
