The correct answer to this would be the second graph. Going up from the quadrants II and III. :)
Answer:
Rate of change, or slope, is 0.
Step-by-step explanation:
Normally, we would say that the number with the -3x if there was one, would be called B but seeming as there is no number, I can only assume that the rate of change is 0. So the point would be (0,0).
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.
Your answer will be C because you just divide by 2
The one worth $10 because it’s the most reasonable estimate,
