A survey was done that asked people to indicate whether they preferred running outdoors or running indoors. The results of the s
urvey are shown in the two-way table.
Amir is making a relative frequency table from this data.
What operation should Amir perform to determine the relative frequency of a person age 30 and younger who prefers to run outdoors?
Divide 382 by 1027.
Add 681 to 1027, then divide by 1027.
Subtract 382 from 1027, then divide by 1027.
Divide 681 by 1027.

Answer: AAA similarity.
Step-by-step explanation: CB is the transversal for the parallel lines AB and DE, and so by transverse property, we have ∠CED ≅ ∠CBA. Similarly, CA acts as a tranversal for the same pair of parallel lines AB and DE and using the same property, we can have ∠CDE ≅ ∠CAB. Now, in triangles CED and ABC, we have
∠CED ≅ ∠CBA,
∠CDE ≅ ∠CAB
and
∠DCE ≅ ∠ACB [same angle]
Hence, by AAA (angle-angle-angle) similarity,
△CED ~ △ABC.
Thus, the correct option is AAA similarity.
Hey there!
I'm assuming your expression is actually
. If it's not, let me know and I'll be happy to help you out further.
If x were equal to –9, your expression would be undefined. If you solve it with this value plugged in for x, you will get the following:
You can't divide anything by zero. This expression would be undefined if x were –9 since it makes the denominator zero. Therefore, x ≠ –9.
Hope this helped you out! :-)
