Answer:
a) 0.345
b) 0.005
Step-by-step explanation:
We are given the following information in the question:
Mean, μ = 100
Standard Deviation, σ = 0.3
We are given that the distribution of lengths of lumber is a bell shaped distribution that is a normal distribution.
Formula:
a) P(length greater than 100.12 inches)
P(x > 100.12)
Calculation the value from standard normal z table, we have,
b) Standard error due to sampling:
P(length greater than 100.12 inches for the sample)
P(x > 100.12)
Calculation the value from standard normal z table, we have,
Cos(x) has a maximum at x=0
It is also a periodic function with a period of 2pi.So, the values of x for which cos(x) is maximum is x =0, 2Pi, 4π, 6π , .....
and -2π, -4π, -6π , .....
So, The formula gives the x-coordinates of the maximum values for y = cos(x)
