Answer:
0.2196
Step-by-step explanation:
Given that
Mean = 4.56 million visitors per day
Standard deviation = 820,000 visitors per day
According to the given situation the calculation of probability is shown below:-
Here we will find the value of P (3 ≤ X ≤ 4)
= 0.2483 - 0.0287
= 0.2196
Therefore the probability that the web site has between 3 million and 4 million visitors in a single day is 0.2196
Answer:
Step-by-step explanation:
y = Acos(θx + φ)
Amplitude is 5 Α = 5
period is 40° = 1/9 cycle so θ = 9
to start a sine wave using cosine, we must shift 90° φ = -90°
y = 5cos(9x - 90)
