To work out how much a 20lb turkey would cost you have to divide the cost of a 12lb turkey by 12 (15.25/12= 1.27083) as well as dividing the 12lbs by 12 (12/12= 1) then times both numbers by 20 (1.27083 X 20 = 25.42 (rounded)) (1 X 20 = 20) and you have 20lbs turkey=$25.42

7. A large population of ALOHA users manages to generate 60 requests/s, including originals and retransmissions. Time is slotted
Debora [2.8K]

Answer:

P(success at first attempt) = 0.1353

Step-by-step explanation:

This question follows poisson distribution. Thus, the formula is;

P(k) = (e^(-G) × (G)k)/k!

where;

G is number of frames generated in one frame transmission time(or frame slot time)

Let's find G.

To do this, we need to find number of frames generated in 1 slot time which is given as 50 ms.

Now, in 1000 ms, the number of frames generated = 50

Thus; number of frames generated in 50 ms is;

G = (50/1000) × 50

G = 2.5

To find the chance of success on the first attempt will be given by;

P(success at first attempt) = P(0) = e^(-G) = e^(-2) = 0.1353

What is the difference from 10 and 12
goblinko [34]

\huge\text{Hey there!}

\large\text{What is the \bf{difference from 10 and 12}}\large\text{ ?}

\large\text{The word \underline{DIFFERENCE} usually it means \underline{SUBTRACT} in}\\\large\text{mathematical terms.}

\large\text{So, we will reword  the question saying 10 SUBTRACTED by 12}

\large\text{10 - 12 = \bf -2}

\large\text{12 - 10 = \bf 2}

\boxed{\huge\textsf{The difference from 10 \& 12 is: \boxed{\huge\text{\bf -2 or 2 }}}}\huge\checkmark

\text{Good luck on your assignment and enjoy your day!}
