Answer:
Step-by-step explanation:
Let us begin with the AA Similarity definition. It states that if two angles of one triangle are congruent to two angles of another triangle, then the triangles are similar.
This means that we need:
- An angle of one triangle that is congruent to an angle of the other triangle.
- Another angle of one triangle that is congruent to another angle of the other triangle.
For this problem, it is unclear that there are more than one angles that are congruent to each other. We see that angle <DEF and <ABC are congruent, but the problem does not give any other angles. In another case, we must find one more to prove similarity by the AA similarity theorem.
Answer:
a) 0.437; b) 0.291
Step-by-step explanation:
For part a,
There are 280+210 = 490 people that are over 18 years old. Out of these, 119+95 = 214 purchase 2 pairs of jeans annually. This is
214/490 ≈ 0.437
For part b,
There are 87+69+74+11 = 241 people who purchase 3 or more pairs of jeans. There were a total of 220+290+280+210 = 1000 people; this means there were 759 people tho purchased fewer than 3 pairs of jeans.
Out of these, 21+74+126 = 221 were in the age group 12-18. This gives us
221/759 ≈ 0.291
