Answer:

Range = (7,5,-1,-9)

Point 1 = ( -3, 7)

Point 2 = ( -2, 5)

Point 3 = ( 1, -1)

Point 4 = ( 5, -9)

Step-by-step explanation:

g(x)= 1-2x

The domain is x.

The range is y.

g(x) is the function.

To solve this you just input each number from the domain into the function.

g(x) = 1 - 2(-3)

-2 × -3 = positive 6

It is a positive because a negative multipled by a negative equals a positive. This means it is not 1-6 because it is not a negative, it would be 1+6.

1 + 6 = 7

g(x) = 1 -2(-2)

-2 × -2 = positive 4

1 + 4 = 5

g(x)= 1 - 2(1)

-2 × 1 = -2

Since it is multipled 1 time it will be -2. So the equation is still 1-2.

1 - 2 = -1

g(x)= 1 - 2(5)

-2 × 5= -10

A negative multipled by a positive is a negative.

1 - 10 = -9

Now that you have all the numbers put them in parentheses things like the domain

Range = {7,5,-1,-9}

To graph it you need to put in each point by finding the first number of the domain and range and that is your point.

The first point would be (-3,7) and so on and so forth.

Write the name of the period that has the digits 913.

sergejj [24]

The name of period that has the digits 913 is hundreds.<span>
Because Period is considered to a group of places of the digits.</span>

In this case, the given number is 913 and it is the group of hundred because 900 is the highest number it contains.

We can also write 913 as

913 = 900 + 10 + 3

It means,

<span>9 hundreds + 10 tens + 3 ones</span>

Assume that the Poisson distribution applies and that the mean number of hurricanes in a certain area is 6.9 per year. a. Find t

VLD [36.1K]

Answer:

a) 9.52% probability that, in a year, there will be 4 hurricanes.

b) 4.284 years are expected to have 4 hurricanes.

c) The value of 4 is very close to the expected value of 4.284, so the Poisson distribution works well here.

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 time interval.

6.9 per year.

This means that $\mu = 6.9$

a. Find the probability that, in a year, there will be 4 hurricanes.

This is P(X = 4).

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

$P(X = 4) = \frac{e^{-6.9}*(6.9)^{4}}{(4)!}$

$P(X = 4) = 0.0952$

9.52% probability that, in a year, there will be 4 hurricanes.

b. In a 45-year period, how many years are expected to have 4 hurricanes?

For each year, the probability is 0.0952.

Multiplying by 45

45*0.0952 = 4.284.

4.284 years are expected to have 4 hurricanes.

c. How does the result from part (b) compare to a recent period of 45 years in which 4 years had 4 hurricanes? Does the Poisson distribution work well here?

The value of 4 is very close to the expected value of 4.284, so the Poisson distribution works well here.
