The correct answer should be 9
Answer: Symmetrical, Bell-shaped
Step-by-step explanation:
The Normal Probability Distribution is very popular among all because of its unique mathematical characteristics like
- Normal distributions are symmetric.
- They are unimodal (i.e. it has only one mode).
- All mean, median, mode are equal.
- It is symmetrical around center where mean, median and mode lies.
- Its curve is always a bell shaped curve.
Hence, the major characteristics of a normal probability distribution:
Symmetrical, Bell-shaped
Answer:
Step-by-step explanation:
Tan
tan
(3π) = Undefined
2
Just remember that, the periodicity of tan function is π.
Tan tan
(3π)
2
Break down the angle inside the function by applying the fraction rule
a+b = a +b
c. c. c as: = tan (2π + π )
2
Simply: = tan (π+π)
2
As stated above,
tan (π+x)=tan(x) we get: = tan( π)

B^-2/ab^-3 = b^-2/b^-3 x 1/a = b^[-2-(-3)] x 1/a = b x 1/a = b/a
