<u><em>Answer:</em></u>
The shorter leg is inches
<u><em>Explanation:</em></u>
The 30°-60°-90° is a special type of right-angled triangles
<u>It has the following special side length:</u>
The length of the side opposite to the 30° is the length of the hypotenuse
The length of the side opposite to the 60° is of the hypotenuse
<u>Now, we know that</u> the lengths of the sides in a triangle are proportional to the angles
<u>This means that</u> the shortest side will be the one opposite to the smallest angles
In our case, the shortest side will be the one opposite to the 30° angle
We are given that the hypotenuse of the triangle is in
<u>From the above:</u>
Shorter leg = leg opposite to 30° = inches
Hope this helps :)
Answer:
0.0671% probability that at least 5 of them are born either in April or in October
Step-by-step explanation:
For each student, there are only two possible outcomes. Either they were born in April or October, or they were not. The probabilty of a student being born in April or October is independent of other students. So we use the binomial probability distribution to solve this question.
Binomial probability distribution
The binomial probability is the probability of exactly x successes on n repeated trials, and X can only have two outcomes.
In which is the number of different combinations of x objects from a set of n elements, given by the following formula.
And p is the probability of X happening.
Probability of a student being born in April or October
April has 30 days, October 31
The year has 365 days. So
A graduate class consists of six students.
This means that
What is the probability that at least 5 of them are born either in April or in October?
In which
0.0671% probability that at least 5 of them are born either in April or in October
