Area=(Theta/2) * r^2 This should be it, obviously Theta is your angle and you should use radiants in theory.
<u>To make this problem solvable, I have replaced the 't' in the second equation for a 'y'.</u>
Answer:
<em>x = -9</em>
<em>y = 2</em>
Step-by-step explanation:
<u>Solve the system:</u>
2x + 3y = -12 [1]
2x + y = -16 [2]
Subtracting [1] and [2]:
3y - y = -12 + 16
2y = 4
y = 4/2 = 2
From [1]:
2x + 3(2) = -12
2x + 6 = -12
2x = -18
x = -18/2 = -9
Solution:
x = -9
y = 2
Answer:
The probability of cured people in who took the remedy is 8/9.
Step-by-step explanation:
Success rate of the cold remedy = 88%
The number of people who took the remedy = 45
Now, 88% of 45 = ![\frac{88}{100} \times 45 = 39.6](https://tex.z-dn.net/?f=%5Cfrac%7B88%7D%7B100%7D%20%20%5Ctimes%2045%20%3D%2039.6)
and 39.6 ≈ 40
So, out of 45 people, the remedy worked on total 40 people.
Now, let E: Event of people being cured by cold remedy
Favorable outcomes = 40
![\textrm{Probability of Event E} = \frac{\textrm{Total number of favorable outcomes}}{\textrm{Total outcomes}}](https://tex.z-dn.net/?f=%5Ctextrm%7BProbability%20of%20Event%20E%7D%20%20%3D%20%5Cfrac%7B%5Ctextrm%7BTotal%20number%20of%20favorable%20outcomes%7D%7D%7B%5Ctextrm%7BTotal%20outcomes%7D%7D)
or,
= ![\frac{8}{9}](https://tex.z-dn.net/?f=%5Cfrac%7B8%7D%7B9%7D)
Hence, the probability of cured people in who took the remedy is 8/9.
