Answer:
Step-by-step explanation:
Given: The number of multiple choices to each question = 3
We know that in multiple choice question there is only one answer is correct .
Then the probability that she will guess correctly on any question is given by :-
Hence, the the probability that she will guess correctly on the fourth question =

Step-by-step explanation:
The two triangles are <em>similar</em> because they have:
- a common angle (90°)
- corresponding sides with lengths in a 3:1 ratio
All you need to do is to slide the smaller triangle into the larger one so that a small angle and one of its sides coincide.
Then the hypotenuses of each triangle will lie along the same line.
Answer: 27
Step-by-step explanation:
you can isolate the separate terms so you get
