Answer:

a) 0.12386 = 12.386% probability that in a year, there will be 3 hurricanes.

b) 5.57 years are expected to have 3 hurricanes, that is, between 5 and 6 years.

c) 5 years is very close to the mean of 5.57, which means that 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:

[tex]P(X = x) = \frac{e^{-\mu}*\mu^{x}}{(x)!}[/tex]

In which

x is the number of sucesses

e = 2.71828 is the Euler number

[tex]\mu[/tex] is the mean in the given interval.

The mean number of hurricanes in a certain area is 5.3 per year.

This means that [tex]\mu = 5.3[/tex]

a. Find the probability that in a year, there will be 3 hurricanes.

This is P(X = 3).

[tex]P(X = x) = \frac{e^{-\mu}*\mu^{x}}{(x)!}[/tex]

[tex]P(X = x) = \frac{e^{-5.3}*5.3^{3}}{(3)!} = 0.12386[/tex]

0.12386 = 12.386% probability that in a year, there will be 3 hurricanes.

b. in a 45-year period, how many years are expected to have 3 hurricanes ?

0.12386 each year. So, for 45 years:

45*0.12386 = 5.57

5.57 years are expected to have 3 hurricanes, that is, between 5 and 6 years.

c. How does the result from part (b) compare to a recent period of 45 years in which 5 years had 3 hurricanes? Does the Poisson distribution work well here?

5 years is very close to the mean of 5.57, which means that the Poisson distribution works well here.

Answer: $5.44

Step-by-step explanation:

18% of 50= 9 pennies

36% of 50= 18 dimes

9 + 2= 11 nickels

9+18+11= 38 pennies, nickels and dimes.

50 (total amount of coins) - 38 (pennies nickels and dimes)= 12 quarters.

9 pennies= 9 cents

18 dimes= 180 cents

11 nickels= 55 cents

12 quarters= 300 cents

9 + 180 + 55 + 300= 544 cents= $5.44

Answer:

$5.44

The bag contains $5.44.

Step-by-step explanation:

Pennies:

50(18/100)= 9 pennies

Dimes:

50(36/100)= 18 dimes

Nickels:

2 more nickels than pennies

9+2= 11

Quarters:

9+18+11= 38

50-38= 12 quarters

1 penny = 0.01 dollar

9x0.01= 0.09

1 dime = 0.10 dollar

18x0.10= 1.80

1 nickel = 0.05 dollar

11x0.05= 0.55

1 quarter = 0.25 dollar

12x0.25= 3

0.09+1.80+0.55+3= $5.44

Answer:

Y=-6x

Step-by-step explanation:

Choose two points from the graph (0,0) and (1,-6)

Average Rate of Change= (y2-y1)/(x2-x1)

(-6-0)/(1-0)=-6/1=-6

y=-6x+b

0=-6(0)+b

0=0+b

0=b

Y=-6x+0

Y=-6x

Answer:

40ft

Step-by-step explanation:

Add up all four sides of your rectangle:

15ft + 15ft +5ft + 5ft = 40ft

You can find the other 5ft (the side that is missing) if you notice that the smaller sections are squares.

Sorry if it's wrong..

The coefficient is the number next to the letter.

Although the x squared term has a coefficient of 1, it is not listed in the answer choices. However, the coefficient of the middle term 6x is listed.

Answer: 6

Step-by-step explanation:

C≈3.54

Using the formulas

A=πr2

C=2πr

Solving for C

C=2πA=2·π·1≈3.54491

Answer:

d=-1

Step-by-step explanation:

10(1+3d)= -20

divide both sides by 10

1+3d=-2

move the costant to the right, change the sign

3d=-2-1

caclulate

3d=-3

divide both sides by 3

d=-1

Answer:

Step-by-step explanation:

Answer:

y = -2x

Step-by-step explanation:

Equation in slope-intercept form is y = mx + b.

m = slope = ∆y/∆x

Using any two points on the line, say (0, 0) and (-20, 40),

Slope (m) = (40 - 0) / (-20 - 0) = 40/-20

Slope (m) = -2

b = y-intercept = the value of y when x = 0.

b = 0

To write the equation of the line, substitute m = -2 and b = 0 into y = mx + b

Thus:

y = -2x + 0

y = -2x

Answer:

Step-by-step explanation:

Yes it's a function.

You may be looking at v which produces m

You may be looking at r which also produces m.

That's fine. Two different x values (the domain) can produce the same y value. Lots of functions do that. (you'll study parabolas pretty soon and all that open up or down have two x values producing the same y value).

If you have a member of the domain producing 2 y values,  that doesn't work. That would not be a function.

This example is a function.
