Please see the attached pictures for full solution.
Establish two right triangles, both with the height of the pole, h.
Call x the distance from the pole to one stake. Then the distance from the other stake to the pole is 6 -x.
Apply Pytagora's equation to both triangles.
1) h^2 = 7^2 - x^2
2) h^2 = 8^2 - (6-x)^2
Eaual 1 to 2
7^2 - x^2 = 8^2 - 6^2 +12x -x^2
12x = 7^2 -8^2 +6^2 = 49 -64 + 36 = 21
x = 1.75
Substitue x-value in 1
h^2 = 49 - (1.75)^2 = 45.94
h = sqrt(45.94) = 6.78
Answer: option d.
Probability of an event happening is given by:
probability of an event happening=number of ways it can happen/total number of outcomes
number of random selection=40
total number of patients who did not leave against medical advice=52,560
thus the probability that at random selection none of the 40 patients left the treatment center against medical advice will be:
40/52560
=0.00076
So you want to add together 4, 6, 11, and 9.
So to make it easier, I would first add together 4 and 6, and 11 and 9.
4 and 6 added together is 10
11 and 9 added together is 20
So, just 20 + 10, or 30.
