X = 8.5 because 8.5 x 2 = 17 and 17 + 1 = 18
Answer:
A = 45
B = 90
C = 45
Step-by-step explanation:
Isosceles triangles have two side that are the same and two angles that are the same. Since one angle, B, is a right angle, 90°, that means the other 2 angles, A & C, added together equal 90°.
Divide 90 by 2 and you 45° for both A and C.
Using it's concept, it is found that there is a 0.8 = 80% probability that the learner is a senior or a male.
<h3>What is a probability?</h3>
A probability is given by the <u>number of desired outcomes divided by the number of total outcomes</u>.
In this problem, there is a total of 6 + 4 + 5 = 15 students. Of those, there are 6 seniors, and 6 male non-seniors, hence there are 12 desired outcomes, and the probability is given by:
p = 12/15 = 0.8 = 80%.
