Answer:

Step-by-step explanation:

Notice how each new term of this sequence is 7 greater than the previous term.

Thus, the common difference is 7. The first term is -4.

A formula for the nth term is a(n) = -4 + 7(n-1).

A recursive formula would be a(n+1) = a(n) + 7

ICE Princess25 [194]

In year 10, the table says the population is 25,000

But if we plugged x = 10 into the equation Lucy got, then,

y = 600x + 25000

y = 600(10) + 25000

y = 6000 + 25000

y = 31000

Lucy's equation says that the population in year x = 10 should be y = 31000 instead of 25000. So this is one way to show that there is an error. The output from the equation isn't matching what the table shows.

If electricity power failures occur according to a Poisson distribution with an average of 3 failures every twenty weeks, calcul

Wittaler [7]

Answer:

0.9898 = 98.98% probability that there will not be more than one failure during a particular week.

Step-by-step explanation:

In a Poisson distribution, the probability that X represents the number of successes of a random variable is given by the following formula:

$P(X = x) = \frac{e^{-\mu}*\mu^{x}}{(x)!}$

In which

x is the number of sucesses

e = 2.71828 is the Euler number

$\mu$ is the mean in the given interval.

3 failures every twenty weeks

This means that for 1 week, $\mu = \frac{3}{20} = 0.15$

Calculate the probability that there will not be more than one failure during a particular week.

Probability of at most one failure, so:

$P(X \leq 1) = P(X = 0) + P(X = 1)$

Then

$P(X = x) = \frac{e^{-\mu}*\mu^{x}}{(x)!}$

$P(X = 0) = \frac{e^{-0.15}*0.15^{0}}{(0)!} = 0.8607$

$P(X = 1) = \frac{e^{-0.15}*0.15^{1}}{(1)!} = 0.1291$

Then

$P(X \leq 1) = P(X = 0) + P(X = 1) = 0.8607 + 0.1291 = 0.9898$

0.9898 = 98.98% probability that there will not be more than one failure during a particular week.
