A life insurance salesman sells on the average 4 life insurance policies per week.
a. What is the probability that in a given week he will sell three policies? (round your answer to three decimal places)
b. What is the probability that he will sell at most 5 policies in two weeks period? ( round your answer to three decimal places)
Answers
Answer:
0.195
0.191
Step-by-step explanation:
Given that :
μ = 4
Using poisson :
P(x) = (e^-μ * μ^x) ÷ x!
P(x = 3) = (e^-4 * 4^3) / 3!
= (0.0183156 * 64) / 6
= 0.1953664
= 0.195
b. What is the probability that he will sell at most 5 policies in two weeks period?
Mean per week = 4
Mean in two weeks = 4 * 2 = 8
P(x ≤ 5) = p(5) + p(4) +... + p(0)
Using the poisson distribution calculator :
P(x ≤ 5) = 0.19124
= 0.191
Suppose x be a random variable that refers to the number of life insurance plans sold by salespeople using Poisson. Assuming that the average number of insurance policies sold per week is
[tex]\lambda=4[/tex]
we know that,
[tex]\bold{P(X=x) = \frac{e^{-\lambda} \times \lambda^{x}} {x!}}[/tex]
For point a:
Probability which is required:
[tex]P(X=3)\\\\\small P(X=3) = \frac{e^{-4} \times 4^{3}} {3! }\\\\\small P(X=3) =0.1954\\\\[/tex]
For point b:
For the next 2 weeks, the average amount of insurance policies sold:
[tex]\small \lambda = 4\times 2=8[/tex]
Probability which is required:
[tex]P(X\leq 5)[/tex] [tex]\text P(X\leq 5)=P(X=0)+P(X=1)+P(X=2)+P(X=3)+P(X=4)P(X=5)}[/tex]
where
[tex]\small P(X=0) = \frac{e^{-8} \times 8^{0}} {0! } = 0.0003[/tex]
Similarly,
[tex]\small P(X=1) = 0.0027\\\\ \small P(X=2) = 0.0107\\\\ \small P(X=3) = 0.0286\\\\ \small P(X=4) = 0.0573\\\\ \small P(X=5) = 0.0916[/tex]
Therefore,
[tex]\small P(X\leq5) = 0.1912[/tex]

Total consumption of fruit juice in a particular country in 2006 was about 1.76 billion
gallons. The population of that country in 2006 was 500 million. What was the average number of
gallons of fruit juice consumed per person in the country in 2006? Using the per
person amount from this problem, about how many gallons would your class consume?
Answers
Answer:
Step-by-step explanation:
Kindly check explanation
Step-by-step explanation:
The population of that country in 2006 was 500 million. What was the average number of
gallons of fruit juice consumed per person in the country in 2006? Use pencil and paper. Using the per
person amount from this problem, about how many gallons would your class consume?
Total consumption in 2006 = 2.11 billion gallons (2,110,000,000)
Population of country in 2006 = 500,000,000
Average number of gallons of fruit juice consumed per person in the country in 2006:
Total consumption / total population
2,110,000,000 / 500,000,000
= 4.22 gallons per person
Number of gallons class will consume :
Assume number of students in class = 15
Hence, class consumption equals:
Average consumption per person × number of students in class :
4.22 × 15 = 63.3 gallons

Write an equation in slope-intercept form
for a line that goes through the points
(0, 6) and (1, -1).
Answers
Answer:
y = -7x +6
Step-by-step explanation:
Point (x1,y1) = (0,6)
point (x2,y2) = (1,-1)
Points (0,6) and (1,-1)
m = y2 - y1 / x2-x1
m = -1-6 / 1-0
m= -7
y - y1 = m (x - x1)
y - 6 = -7(x - 0)
y = -7x + 6

Solve the system of linear equations by substitution. Check your solution.
Answers
1. Solve one of the equations.
Ex: x-3y=-12 —-> x=3y-12
2. Substitute the equation we just solved into the other equation:
2(3y-12)+4y=-4
3. Simply the problem above to get y=2
4. Substitute y=2 into the other equation (x-3y=-12) and solve
x-3(2)=-12
5. Simplify the equation above to get x=-6
The answer is (-6,2)
The solution to the system of linear equations is x = -6 and y = 2.
Solving the system of linear equations by substitution:
The system of linear equations is:
2x + 4y = -4
x - 3y = -12
We can solve this system by substitution. First, we can solve the second equation for x:
x = 3y - 12
Substituting this expression for x into the first equation, we get:
2(3y - 12) + 4y = -4
Simplifying the right side of the equation, we get:
6y - 24 + 4y = -4
Combining like terms, we get:
10y - 24 = -4
Adding 24 to both sides of the equation, we get:
10y = 20
Dividing both sides of the equation by 10, we get:
y = 2
Now that we know the value of y, we can substitute it into the second equation to solve for x:
x - 3(2) = -12
Simplifying the right side of the equation, we get:
x - 6 = -12
Adding 6 to both sides of the equation, we get:
x = -6
Therefore, the solution to the system of linear equations is x = -6 and y = 2.

Reece drinks one pint of milk a day. He buys milk in 2 litre containers.
How many containers does he need for a week?
Use 134
pints = 1 litre
Answers
Answer:
He needs [tex]\frac{7}{134}[/tex] 2-litre containers in a week.
Step-by-step explanation:
1 day --- 1 pint
1 week --- 7 × 1 pint = 7 pints
1 litre --- 134 pints
2 litres --- 2 × 134 pints = 268 pints
268 pints --- 2 litres
7 pints --- [tex]\frac{7}{268}[/tex] × 2 litres = [tex]\frac{7}{134}[/tex] 2-litre containers
Find the perimeter with a length of 13 meters and the other parallel sides have a length of 7 meters. The perimeter of the parallelogram

______
13 meters
P = 2l+2w
Perimeter = 2(13)+2(7)
P = 26+14
P = 40 meters
Its 40 b/c the problem identifies the shape as a parallelogram and that the length is 13 meters while the others are 7 meters. To find the perimeter, you'll just have to add all sides of the measures together or take one length and one width and multiply each of them by 2.

Solve for x and then find the measure of each angle.
Answers
Answer:
x is 60
and all angles
60 120 130 50
Answer:
∠K = 60°
∠N = 120°
∠M = 130°
∠L = 50°
Step-by-step explanation:
Sum of all the angles = 360
x + 2x + 3x - 50 + x -10 = 360
x +2x + 3x + x - 50 - 10 = 360
7x - 60 = 360
7x = 360 + 60
7x = 420
x = 420/7
x = 60
∠K = 60°
∠N = 2*60 = 120°
∠M = 3*60 - 50 = 180 - 50 = 130°
∠L = 60 - 10 = 50°

Answers
Answer:
Percent of people die for drowning = 0.005%
Step-by-step explanation:
Given:
Total population = 72,000,000
Number of people die for drowning = 3,600
Find:
Percent of people die for drowning
Computation:
Percent of people die for drowning = [Number of people die for drowning/Total population]100
