We need the question to be able to solve it
Answer:
Step-by-step explanation:
Given that x is a random variable from a binomial distribution with n = 40 and p = 0.9.
We find that mean = np= 36 and variance = npq = 3.6
Std dev = square root of variance = 1.897
When we approximate binomial to normal we say
X' is Normal with mean = 36 and std dev = 1.897
X' is N(36, 1.897)
Note:
The condition for binomial approximating to normal is p should be close to 1/2
Here p is 0.9 and also nq=4 is very small.
So normal approximation may not give accurate results.

Answer:
3rd choice
Step-by-step explanation:
The domain is (-infinity, infinity) because you can keep subtracting multiples of 360 until you get a value under 360. For the range, imagine a unit circle.
The y coordinate is the sin value, so it is just [-1, 1].
So the answer is the 3rd choice.
Answer:
D) all real numbers
Step-by-step explanation:
The domain is the input values, in this case the x values
What x values can we use
x goes from - infinity to plus infinity, so it is all real numbers
