Answer:
Step-by-step explanation:
Given:
In Δ ABC
m∠C= 90°
For the triangle ABC we can apply trigonometric ratio to find m∠A.
We have:
Substituting values of side BC and AC
Taking inverse tan to get m∠A.
∴
AB can be found out using Pythagorean theorem:
AB being the hypotenuse can be written as
Substituting values of side BC and AC
Taking square roots both sides:
∴
Answer:
Step-by-step explanation:
If the mean of 15 students is 71.5, then total score = 15 X 71.5 = 1072.5
The median score is 62, meaning that, the combined score of two students = 62 X 2 = 124
The difference of 1072.5 and 124 = 948.5, this represents the total score of 13 other students
∴ The mean score of 13 students = 948.5/13 = 73
In conclusion, it was only very few students that took the exam and majority of other students absconded from the exam. Majority of students scored averagely above 70.
