ANSWER
Midline y=-1
Period= 2π
Amplitude=3
Frequency=1
EXPLANATION
The given function completes one cycle on the interval 0 to 2π.
Therefore the period of the function is
The midline divides the graph into two equal halves.
This line is y=-1
The cycle repeated once on the interval [0,2π] hence the frequency is 1.
The amplitude is the distance from the midline to the peak.

Answer:
The required probability is 0.55404.
Step-by-step explanation:
Consider the provided information.
The number of typographical errors on a page of the first booklet is a Poisson random variable with mean 0.2. The number of typographical errors on a page of second booklet is a Poisson random variable with mean 0.3.
Average error for 7 pages booklet and 5 pages booklet series is:
λ = 0.2×7 + 0.3×5 = 2.9
According to Poisson distribution:
Where is average number of events.
The probability of more than 2 typographical errors in the two booklets in total is:
Substitute the respective values in the above formula.
Hence, the required probability is 0.55404.
