If m = 27 and n = 4, what is the value of the following expression?
Answer:
2
Step-by-step explanation:
m - 5 • n + 5
plug it in
27- 5 * 4+5
well, we gotta follow PEMDAS (there are no parentheses)
5*4
20
now we have
27-20+5
20+5
25

Assume that the Poisson distribution applies and that the mean number of hurricanes in a certain area is 5.3 per year. a. Find the 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 ? 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?
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.

Can anyone help me out on this
Answer:
y=x+10
Step-by-step explanation:
y=mx+b
y=1x+b
1 because for every 10 it goes to the right, it goes up 10 as well.
b=10 because the function crosses the y-axis at 10
so
y=x+10

What is the slope of the line shown below?
Answer:
A. 2
Step-by-step explanation:
Formula for slope of a line (m) = change in y / change in x = ∆y/∆x
Using the coordinates of two points on the line, (1, -4) and (6, 6):
Slope (m) = (6 - (-4)) / (6 - 1) = 10/5 = 2
Slope (m) = 2
Express as a difference. 7+3. Please explain.
Answer:
7 + 3 = 10, difference means the answer to a subtraction problem, not sure I understand the question
Step-by-step explanation:
The given expression (7 + 3) represented in difference form as [tex]7-(-3)[/tex]
Difference of numbers :
We have to express 7 + 3 as difference of two number.
As we know that,
[tex]a-(-b)=a+b[/tex]
In above expression, (a + b) is difference of two number a and -b.
Similarly,
[tex]7+3=7-(-3)[/tex]
Thus, (7 + 3) represented in difference form as [tex]7-(-3)[/tex]
