Answer:

geometric

arithmetic

Step-by-step explanation:

there are no statements to check. you did not copy them in.

but I can solve the first part of the question.

sequence 1 :

-10, 20, -40, 80, -160, 320, -640, ...

I extended the sequence by a few more terms.

but it is clear that each new term is the previous term multiplied by -2.

since the sequence is built by multiplication, it is geometric.

sequence 2:

15, -5, -25, -45, -65, -85, ...

so, it is clear that each new term is the previous term subtracted by -20.

since the sequence is built by adding or subtracting, it is arithmetic.

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

To compare 5 in tens place to 5 in the hundreds place in the number 5,555
galina1969 [7]

Answer:

I'm not sure what you are asking for?

Step-by-step explanation:

The 5 in the tens place = 50, and the 5 in the hundreds place = 500.

To compare them (Are you asking me for the difference between them???), then, 500 - 50 = 450.

But, again, I'm not sure what you want.
