Vì tam giác ABC cân tại A (gt) mà AM là đg trung tuyến nên AM đồng thời là đg cao của t/giác đó:

AM là trung tuyến của t/giác ABC nên M là trung điểm BC:

=> BM =BC/2 =6:2=3(cm)

Xét tam giác AMB vuông tại M

AB^2 =AM^2+BM^2 ( theo định lý Py-ta -go)

Answer: a) 0.333, b) 0.333 and c) 0.9986.

Step-by-step explanation:

Since we have given that

Average = 3 counts per minute = λ

a) What is the mean time between counts ?

Since it follows a Poisson Process, So,

$E[x]=\dfrac{1}{\lambda}=\dfrac{1}{3}=0.333$

(b) What is the standard deviation between counts ?

$\sigma=\dfrac{1}{3}=0.333$

(c) If it is an average of 3 counts per minute, find the value of such that .

If the average = 3 counts per minute.

Then, $P(X$

Hence, a) 0.333, b) 0.333 and c) 0.9986.
