Step-by-step explanation:
True for all x.
It is asking to find the cost (c) for (p) number of pizzas at $8 each. So 1 pizza would be $8 and 2 would be 2 * 8 = 16 and 3 would be 3 * 8 = 24 and 4 would be 4 * 8 = 32 and p would be p * 8 = c. So the answer is:
c = 8p
15. a ratio is a fraction comparing numbers showing how they relate to each other.
if she mixed 3 ounces of blue and 2 of yellow, this would make 5 ounces of green paint. So the ratio is 3/2. to get 20 ounces of green paint she would have to do this mixture 4 times since she gets five each time. If she mixes 2 ounces of yellow paint four times, she would use 4 * 2 = 8 ounces of yellow painy

Step-by-step explanation:
To obtain, the maximum likelihood ratio, we use the following method.
l(σ) = Xn
i=1 "
− log 2 − log σ −

Let the derivative with respect to θ be zero:
l

(σ) = Xn

and this gives us the MLE for σ as
σˆ =

Again this is different from the method of moment estimation which is
σˆ =
