A school was trying to determine whether or not students would like to have late arrival one day. They surveyed 25 students from each class and the results are shown in the table.

To see if this was typical they also conducted a simulation to see how many seniors should have responded yes. They completed this simulation 30 times and the results are shown in the dotplot. Were the results typical? Explain.

Use the following statements to write a compound statement for the conjunction or disjunction. then find its truth value. p: an isosceles triangle has two congruent sides. q: a right angle measures 90° r: four points are always coplanar. s: a decagon has 12 sides. a) a right angle measures 90° or an isosceles triangle has two congruent sides; true. b) a right angle measures 90° and an isosceles triangle has two congruent sides; true. c) a right angle measures 90° and an isosceles triangle does not have two congruent sides; false. d) a right angle measures 90° or an isosceles triangle does not have two congruent sides; true.
