80 students like bike riding
20 students like bike riding but do not like skating
90 students like skating
40 students do not like bike riding
Make a two-way table to represent the data and use the table to answer the following questions.
Part A: What percentage of the total students surveyed like both bike riding and skating? Show your work.
Part B: What is the probability that a student who does not like bike riding also does not like skating?
I don't know how to do the graph.
Part A: 80+20+90+40= 230 students. 90 for skating + 80 for biking= 170 170/230= 0.74 =74%
Part B: 20 for no skating+ 40 for not biking = 60. The probability is 60 out of 230 students
Answer:
Rhombus
Rectangle
Square
Step-by-step explanation:
A parallelogram is a shape of four sides, quadrilateral, that has equal and opposite sides. In this case, the problem is asking to name three kinds of parallelograms to complete the hierarchy.
In the hierarchy, quadrilaterals come first because a quadrilateral is a polygon of four edges, no matter if the sides of the polygon are irregular.
Then comes the parallelograms that are quadrilaterals with equal, opposite sides.
And some types of parallelograms are:
Rhombus in which all the sides are equal but the angles are not right angles
Rectangle that has right angles
Square all the sides are equal and it has right angles
You can choose more than one.
