Suppose that appearances of a foe to battle (that is, a random encounter) in a role-playing game occur according to a Poisson pr

Dimas [21]

Answer:

Rate parameter of $\mu = 0.5$

Step-by-step explanation:

Exponential distribution:

The exponential probability distribution, with mean m, is described by the following equation:

$f(x) = \mu e^{-\mu x}$

In which $\mu = \frac{1}{m}$ is the decay parameter.

One appearance per two minutes.

This means that $m = 2$

Measured in minutes, the time T until the next encounter is Exponential with what rate parameter?

$\mu = \frac{1}{m} = \frac{1}{2} = 0.5$

So

Rate parameter of $\mu = 0.5$

The angle of NPR is 130°

First, set up an equation to find x.

$(3x-10)+2x+65=180$

Then, solve the equation for x.

$x=25$

Then, substitute 25 in for x in 2x

50

Finally, subtract 50 from 180 to find the angle of NPR

brilliants [131]

Answer:

A.. Number of elements in the sample space is 10.

B.. Given that event B is card drawn is blue.

Step-by-step explanation:

Special deck has3 blue and 7 orange cards. The blue cards are numbered 1, 2 and 3. The orange cards are numbered 1, 2, 3, 4, 5, 6 and 7.

We draw one card randomly from the deck, the sample space is

S={b1, b2, b3, o1, o2, o3, o4, o4, o6, o7}

Where,

'b' represents blue card

And 'o' represents orange cards.

Number of elements in the sample space is 10.

Given that event B is card drawn is blue.

B={b1, b2, b3}.
