Answer:
4
Step-by-step explanation:
To find the mean absolute deviation (MAD), first find the mean (or average).
μ = (59 + 71 + 68 + 75 + 67) / 5
μ = 68
Next, subtract the mean from each value and take the absolute value.
|59 − 68| = 9
|71 − 68| = 3
|68 − 68| = 0
|75 − 68| = 7
|67 − 68| = 1
Sum the results and divide by the number of students.
MAD = (9 + 3 + 0 + 7 + 1) / 5
MAD = 4
Answer:
<em>Camera 2nd has to cover the maximum angle, i.e. </em>.
Step-by-step explanation:
Please have a look at the triangular park represented as a triangle with sides
a = 110 ft
b = 158 ft
c = 137 ft
1st camera is located at point C, 2nd camera at point B and 3rd camera at point A respectively.
We can use law of cosines here, to find out the angles
As per Law of cosine:
Putting the values of a,b and c to find out angles .
<em>Camera 2nd has to cover the maximum angle</em>, i.e. .
