Find two consecutive even integers such that twice the smaller is 26 less than 3 times the smaller
Answer:
let x = smaller number; x+2 = larger
Step-by-step explanation:
2x = 3x - 26
-x = -26
x = 26
x+2 = 28
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)
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]

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
Is?
Answer:
P = 40 meters
Step-by-step explanation:
13 meters
______
/ / 7 meters (both sides)
______
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.
hopefully that helps :)) peep the diagram lol

Se um capital de R$ 1200,00 for aplicado a uma taxa de 10 % a.m durante 4 meses quanto renderá de juros ?
Responder:
$ 1240
Explicación paso a paso:
Podemos calcular la cantidad equivalente del dinero después de 4 meses
Primero obtén el interés simple
SI = PRT / 100
P es el principal = $ 1200,00
Tasa R = 10%
TIEMPO t = 4 meses = 4/12 años
SI = 1200 * 10 * 1/300
SI = 12000/300
SI = $ 40
Monto después de 4 meses = Principal + Intereses
Monto después de 4 meses = $ 1200 + $ 40
Monto después de 4 meses = $ 1240
Suppose that in a country of 72 million people, about 3600 die from drowning each year. What is the percent chance that a person will drown in a given year?
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
Percent of people die for drowning = [3,600 / 72,000,000]100
Percent of people die for drowning = 0.005%

You find out there is a new piza place in town. They cut pizzas into 16 slices and the pizza costs $15. Write an expression showing the number of slices of pizza you would have it you purchased n number of pizzas
Answer:
16n
Step-by-step explanation:
This question might be tricking you or you don't have the full question...but it asks for number of slices you would have, nothing about cost. Since each pizza will have 16 slices, it would be 16n
Write an equation in slope-intercept form
for a line that goes through the points
(0, 6) and (1, -1).
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 for x and then find the measure of each angle.
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°
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
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

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?
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

Let f(x) = x² + 3x
What is f(-1) ?
Need help ASAP !!!!
Answer:
-2
Step-by-step explanation:
f(x) = x² +3x
so f(-1) means f(x= -1) so wherever you see a "x" in your equation you put a "-1"
f(-1) = (-1)² +3*(-1) = 1 -3 = -2

NEED HELP PLS Find the value of X. Round to the nearest tenths place
Hello!
[tex]\large\boxed{x = 15}[/tex]
Use the Pythagorean Theorem to solve for x:
a² + b² = c²
We are given the lengths of two sides, so we can plug those into the formula:
9² + 12² = x²
81 + 144 = x²
225 = x²
√225 = x
x = 15.
Nate prepared 21 kilograms of dough after working 7 hours. How many hours did Nate work if he prepared 27 kilograms of dough? Assume the relationship is directly proportional
Answer:
the awnser is 9
Step-by-step explanation:
because if it takes 7 h to make 21 k of dough that means every hour he makes 3 k of dough and to get to 27 we need to do this : 3x2=6 , and 21 +6= 27 and since every hour he makes 3 k of dough and we multiplyed 3x2 that means we have to add 7 +2=9 that is how we solve:)
