Answer:
The answer is "
".
Step-by-step explanation:
considering 
signify a random Poisson distribution of the sample size of n which means is λ.
Let assume that,
multiply the above value by Var on both sides:
now consider 
= 
For calculating the efficiency divides the 
value:
Formula:
I can't answer the question since this is only a fragment of the whole thing, but I can tell you how to answer it based off of the info given. 5 dozen is 60 cookies, so, depending on how much the recipe makes, just multiply the amounts the recipe calls for in order to make it explain how to make 60 cookies. For example, if the recipe makes 12 cookies with (I'll just make up this recipe, since I'm not much of a baker):
4 eggs
2 1/2 cups of flour
3 oz of milk
2 sticks of butter
and 1 1/4 oz of water, all you have to do is multiply all of those numbers by five, since 12*5 = 60 cookies, and there's how to answer it.
I could have a more accurate answer if you provide details, but that's how I'm guessing the question wants you to answer it.
Answer:
-6x^2-288
Step-by-step explanation:
18x - 432 - 18x - 6x² +144
Combine like terms
-6x^2+18x-18x-432+144
-6x^2-288
Mean of a set of numbers is the quotient when their sum is divided by the number of items in the set. For the given above, their sum (S) is,
S = 5.2 + 8.3 + 8.5 + 7.7 + 7.8 + y = 37.5 + y
The mean (m) is calculated through the formula,
m = S / n
where n is the number of items. In this given there are 6 items including y.
7.1 = (37.5 + y) / 6 ; y = 5.1
Therefore, y is equal to 5.1.
