Answer:
=760
Step-by-step explanation:
Area: 
diameter= 44
radios= 22
area of full circle:
3.14(22)^2
= 1519.76
Area of half circle"
1519.76/2= 759.88
=760
Answer:
D
Step-by-step explanation:
Given: Mean of Normal distribution μ = 100, standard deviation σ =20
We have to find the probability that the score will be less than X=84
P(X < 84)
The z-score for x=84 is
Z = 
Z = 
Z = -0.8
We have to find probability that Z < -0.8
Using Z score table to find the probability below z=-0.8 we get
P(Z < -0.8) = 0.2119
Hence the probability that the score will be less than x = 84 is 0.2119
Answer:$2.28
Step-by-step explanation:
Answer:
The amplitude is 
Step-by-step explanation:
Trigonometric function:
A trigonometric function has the following format:
or 
In which the amplitude is A and the period is 
Amplitude of y = 1/2 * cos 5x
The multiplier is 1/2, so this is the amplitude.
