This is a classic puzzle!
The answer is that the probability that the last person ends in up in his proper seat is exactly
1
2
The reasoning goes as follows:
First observe that the fate of the last person is determined the moment either the first or the last seat is selected! This is because the last person will either get the first seat or the last seat. Any other seat will necessarily be taken by the time the last guy gets to 'choose'.
Since at each choice step, the first or last is equally probable to be taken, the last person will get either the first or last with equal probability:

Rock-paper-scissors is a hand game played by two or more people where players choose to sign either rock, paper, or scissors with their hands. We would like to test if players choose between these three options randomly, or if certain options are favored above others. What hypothesis test should we conduct to answer this research question?
a. Chi square test of independence
b. Chi square test of goodness of fit
c. Compare two means
d. Compare two proportions
Answers
Answer:
The hypothesis test should we conduct to answer this research question is:
a. Chi square test of independence
Step-by-step explanation:
The Chi-Square Test of Independence or Association tests the two variables of "if players choose between these three options randomly or if certain options are favored above others." It determines whether there is an association between the two categorical variables, ascertaining whether the variables are independent or related. The chi-squared statistic is computed by taking the difference between a pair of observed values and expected values, and squaring the difference,s and then dividing the squared differences by the expected value. After repeating this process for all the elements involved, the sum is obtained.
The external and the internal radius of a cylindrical pipe of length 50 cm are 3 cm and 2.6cm respectively. find the volume of material contained by the pipe
Answers
Answer:351.86 cc( approximately)
Step-by-step explanation:
The volume of the material = External volume - internal volume
= π3^2×50-π 2.6^2×50
=351.86
The volume of the material by the pipe is 351.86 cc.
What is the volume of a cylinder?The volume of a cylinder is equal to the product of the area of the circular base and the height of a cylinder. The volume of a cylinder is defined as the space occupied by the cylinder as the volume of any three-dimensional shape is the space occupied by it
V = πr²h
where 'r' is the radius of the base (circle) of the cylinder
'h' is the height of the cylinder
Given that the external and the internal radius of a cylindrical pipe are 3 cm and 2.6cm respectively
The length of the pipe is 50 cm
External volume = π(3)²×50 = 1413.71 cc
internal volume = π (2.6)²×50 = 1061.85
The volume of the material = External volume - Internal volume
The volume of the material = 1413.71 - 1061.85
The volume of the material = 351.86 cc

Answers
Answer:
a) 500
b) 9.6 years
Step-by-step explanation:
Population of Ilamas
a) P = 500 e ^0.035t
Find P when t = 0
Solving for P
P = 500 e ^0.035 × 0
P = 500 × e ⁰
P = 500 × 1
P = 500
The population of the Ilamas when t = 0 is 500
b ) Find t when P = 700
P = 500 e ^0.035t
700 = 500 e ^0.035t
Divide both sides by 500
700/500 = 500 e ^0.035t/500
7/5 = e ^0.035t
1.4 = e ^0.035t
Take In of both sides
In 1.4 = In (e ^0.035t)
In 1.4 = 0.035t
t = In 1.4/0.035
t = 0.3364722366/0.035
t = 9.6134924749 years
t = Approximately to the nearest tenth of a year = 9.6 years

Answer:
[tex]y = 3.5x[/tex]
Step-by-step explanation:
Required
Determine the equation
First, pick corresponding x and y values
[tex](x_1,y_1) = (6,21)[/tex]
[tex](x_2,y_2) = (14,49)[/tex]
Next, calculate the slope
[tex]m = \frac{y_2 - y_1}{x_2 - x_1}[/tex]
This gives:
[tex]m = \frac{49 - 21}{14 - 6}[/tex]
[tex]m = \frac{28}{8}[/tex]
[tex]m = 3.5[/tex]
The equation is then calculated using:
[tex]y - y_1 = m(x - x_1)[/tex]
[tex]y - 21 = 3.5(x - 6)[/tex]
[tex]y - 21 = 3.5x - 21[/tex]
Add 21 to both sides
[tex]y - 21+21 = 3.5x - 21+21[/tex]
[tex]y = 3.5x[/tex]

Is (x-1) a factor of 2x3 - 15x2 + 22x + 15
Answers
Answer:
Step-by-step explanation:
If x - 1 is a factor of the cubic, then 1 should result in 0 when you put it in the cubic for x. Does it?
f(1) = 2(1)^3 - 15(1)^2 + 22(1) + 15
f(1) = 2 - 15 + 22 + 15
f(1)= 24.
No the result is not zero. So x - 1 is not a factor.
However there must be something that makes this cubic go to zero. The easiest way to find it is to graph it.
The numbers that do make this zero are -0.5, 3, 5
Which mean that the factors are (2x+1)(x-3)(x - 5)

2. 16 tomatoes.
Step-by-step explanation:
1. Determination of the linear expression.
Let x represent the number of pumpkin.
Let y represent the number of tomato.
Let T represent the total sales made from selling the pumpkins and tomatoes.
From the question,
1 pumpkin = $ 5
Hence,
x pumpkin = 5x
1 tomatoe = $ 3
Hence
y tomatoes = 3y
Therefore, the total sales (T) made from selling the pumpkin and tomatoes will be:
T = 5x + 3y
Where:
T is the total sales made from selling the pumpkin and tomatoes.
x is the number of pumpkin.
y is the number of tomatoe
2. Determination of the number of tomatoes sold.
Total cost (T) = $ 98
Number of pumpkin (x) = 10
Number of tomatoe (y) =?
T = 5x + 3y
98 = 5(10) + 3y
98 = 50 + 3y
Collect like terms
98 – 50 = 3y
48 = 3y
Divide both side by 3
y = 48/3
y = 16
Therefore, 16 tomatoes was sold.
