In a typical children's soccer game, there is one goal scored approximately every 18 minutes. The number of goals scored follows
Alja [10]

Answer:

2.24

Step-by-step explanation:

The probability formula using a Poisson distribution is:

P(k\ events) = \frac{\lambda^{k}e^{-\lambda}}{k!} \\\lambda\ is\ the\ average\ number\ of\ events\ per\ interval \\e\ is\ euler's\ number \\k\ is\ the\ number\ of\ events\ you\ want\ to\ calculate

λ = 90 / 18 = 5 average goals per interval (interval = a game)

So if for example you were interested in the probability of making 2 goals in a game

k = 2

P(k = 2) = \frac{5^{2}e^{-5}}{2!} = 0.084

This was just an example,

The standard deviation is \sqrt{\lambda}

\sigma = \sqrt{\lambda} \\\sigma = \sqrt{5} \\\sigma = 2.24

A prism with a base area of 8 cm² and a height of 6 cm is dilated by a factor of 54 . What is the volume of the dilated prism? E
Aliun [14]

Question:

A prism with a base area of 8 cm² and a height of 6 cm is dilated by a factor of 5/4 .

What is the volume of the dilated prism?

Enter your answer, as a decimal, in the box.

Answer:

The volume of the dilated prism is 93.75 \ {cm}^{3}

Explanation:

A prism with a base area of 8 cm² and a height of 6 cm

The volume of the prism can be determined by the formula, V=Bh

Volume of the prism is given by

V=Bh

V=(8)(6)

V=46\ cm^3

Thus, the volume of the prism is 46 \ {cm}^{3}

It is also given that the volume of the dilated prism is dilated by a factor of \frac{5}{4}

Hence, the new volume is given by

Volume = 48(\frac{5}{4} )^3

             =48(\frac{125}{64} )

             =48(1.953125)

             =93.75 \ {cm}^{3}

Thus, the volume of the dilated prism is 93.75 \ {cm}^{3}

Step 3: multiply 3*Y or in this case 3*2 and you will get 6

Step 4: subtract 40-6 and you will get 34
