Step-by-step explanation:

The answer to the question above is drawn in the attached picture.

Note that the symbol, less than or equal to, is a shaded ring. Also, the inequality is interpreted as zero is less than or equals x and x is less than or equals 2. Hence, the joint inequality is presented as shown in the attached picture.

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 $\sqrt{\lambda}$

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

13 = 1.625 * 8
26 = 1.625 * 16
39 = 1.625 * 24
Therefore y vary directly with x.
Answer: C ) yes ; y = 1.625 x

Alex73 [517]

Answer:

Step-by-step explanation:

The correct answer is D. If we are multiplying by 10 we would move the decimal place one place to the right to show that the number is now 10 times bigger. If we multiply by one hundred. We are getting 100 times bigger, so we would move the decimal place 2 places to the right.

The opposite is true if we are dividing. Instead of moving the decimal to the right to show that the number is getting bigger, we move to the left to show that the number is getting smaller. If we are getting smaller by 10, we would move the decimal one place to the left. In this case, we are getting 100 times smaller so we move the decimal two places to the left.
