Ideally, the smaller the sample population, the more accurate is the sampling result, but it will take longer time if the number of samples is huge.
The answer to the above question is ideally 20 light bulbs per sampling.
Answer:
Step-by-step explanation:
You can’t just substitute 0 for θ. 0 is a constant, not a variable.
secθ = -13/5
cosθ = 1/secθ = -5/13
sin²θ = 1 - cos²θ = 144/169
sinθ = -12/13
cscθ = 1/sinθ = -13/12
tanθ = sinθ/cosθ = 12/5
cotθ = 1/tanθ = 5/12
The correct answer to this question is
D - 5 1/4

The given function is
f(x)= 0.2 x²
Since f(x) will be defined for all real values of x.
So, Domain of f(x) will be ( x| x is a real number.)→This is set builder notation.
Finding the inverse of f(x):
y = 0.2 x²
→ x²= 5 y
→x = 
→ → Inverse of f(x)
Replacing x by y and y by x,we get inverse of the given function
y = 
→ →Domain x ≥ 0, x∈[0,∞]
Graph of function and its inverse are shown below.
0 is the correct is answer only if x=3
