The table shows the ratio between the number of packets and the number of seeds of a certain plant contained in them:

Suppose that the log-ons to a computer network follow a Poisson process with an average of 3 counts per minute. (a) What is the

vampirchik [111]

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.

Find the value of x.

Alisiya [41]

$\huge\bold{To\:find:}$

✎ The value of $x$ .

$\large\mathfrak{{\pmb{\underline{\orange{Solution}}{\orange{:}}}}}$

$\sf\purple{The\:value\:of\:x\:is\:10°. }$

$\large\mathfrak{{\pmb{\underline{\red{Step-by-step\:explanation}}{\orange{:}}}}}$

Since it is right angle,

$Sum \: of \: angles \: = 90° \\ ⇢ 2x °+ 7x° =90 ° \\ ⇢9x° = 90° \\ ⇢x° = \frac{90°}{9} \\ ⇢x° = 10°$

$\sf\blue{Therefore,\:the\:value\:of\:x\:is\:10°.}$

$\huge\bold{To\:verify :}$

$2x° + 7x° = 90° \\ ➡ \: 2 \times 10° +7 \times 10° = 90° \\ ➡ \: 20° + 70° = 90° \\ ➡ \: 90° = 90° \\ ➡ \: L.H.S.=R. H. S$

Hence verified.

mart [117]

The required probability for three numbers rolled on the dice are the sides of a triangle is 31/36.

<h3>What is probability?</h3>

The area of mathematics known as probability studies potential outcomes of events as well as their relative probabilities and distributions. It is based on the likelihood that something will occur. The justification for probability serves as the main foundation for theoretical probability.

Here,

When three dice are rolled, there are 63=216 possible outcomes, or triplets (x, y, z).

Once more, in a triangle, any two sides added together are larger than the third side, or (x+y)>z.

As a result, 186 outcomes or triplets are possible and satisfy this property.

Hence, the required probability is 186/216=31/36.

The required probability is 31/36 for three dice rolls to produce triangle sides.
