Answer:
y-5=5/8(x-8)
Step-by-step explanation:
m=(y2-y1)/(x2-x1)
m=(-5-5)/(-8-8)
m=-10/-16
simplify
m=5/8
y-y1=m(x-x1)
y-5=5/8(x-8)

The St. Petersburg paradox goes as follows. A fair coin is tossed repeatedly until it comes up heads. If the first heads appears on the nth toss, you win $2 n . First, show that the expected monetary value of this game is infinite (the paradox is that no one would actually pay a huge amount to play this game). Second, consider a possible resolution of the paradox: suppose your utility for money is given by a log 2 x b where x is the number of dollars you have. Suppose you start with 0 dollars, what is the expected utility of this game
Answer:
a) attached below
b) 2a + b
Step-by-step explanation:
a) show that the expected monetary value of this game is infinite
Given that the probability of getting first head on nth toss = $2^n
attached below is the prove
b) what is the expected utility of this game
using the Logarithm ; [tex]U(x) = a log_{2} n + b[/tex]
x = number of dollars you have
attached below is a detailed solution to the given problem
What’s the correct answer?
Answer:
1
Step-by-step explanation:
take your intial value multiplied but the value it's retaining. it's losing 4.5%, or .045, so it's keeping .055 of it's value, then to the power of 5 because it's 5 years later
Find
(1) The total surface area of a closed cylindrical petrol storage tank whose diameter
4.2 m. and height 4.5 m.
(i) How much steel sheet was actually used, if 1/12
of the steel was wasted in making
of the tank. (anewer quickly and steps in order )
Answer:
The amount of steel used = 94.38 [tex]m^{2}[/tex]
Step-by-step explanation:
Height of the tank = 4.5 m.
Diameter of the tank = 4.2 m.
But,
radius = [tex]\frac{diameter}{2}[/tex]
= [tex]\frac{4.2}{2}[/tex]
radius = 2.1 m
Total surface area of a cylinder = 2[tex]\pi[/tex]rh + 2[tex]\pi[/tex][tex]r^{2}[/tex]
= 2[tex]\pi[/tex]r(r + h)
= 2 x [tex]\frac{22}{7}[/tex] x 2.1 (2.1 + 4.5)
= 44 x 0.3 (6.6)
= 87.12
Total surface area of a cylinder = 87.12 [tex]m^{2}[/tex]
Since [tex]\frac{1}{12}[/tex] of the steel was wasted, then;
[tex]\frac{1}{12}[/tex] x 87.12 = 7.26 [tex]m^{2}[/tex]
Actual area of steel sheet used = 87.12 + 7.26
= 94.38 [tex]m^{2}[/tex]
Thus, 94.38 [tex]m^{2}[/tex] of steel was used in making the tank.
If the speed of sound is 1230 km/h, calculate the speed of sound in metres per second.
Write down your answer correct to the nearest metre.
Answer:
342 m/s
Step-by-step explanation:
1230x 1000 = 1230000
1230000 / 60 = 20500
20500 / 60 = 341.666 = 342

If 20% of a number is 160 then the original number is
Answer:
800
Step-by-step explanation:
160 * 100% / 20% = 800
If 20% of a number is 160 then the original number is 800.
What is Percentage?percentage, a relative value indicating hundredth parts of any quantity.
Given that 20% of number is 160
We need to find the original number.
Let the original number be x
Convert 20% to decimal value by dividing 20 with 100
20/100=0.2
Now multiply 0.2 with x which is equal to 160
0.2x=160
Divide both sides by 0.2
x=800
Hence, If 20% of a number is 160 then the original number is 800.

Xby the power of 5 times y to the power of 6 over 2 by the power of -2 times xby the power of 0times x by the power of 9
Answer:
We have the sentence:
"X by the power of 5 times y to the power of 6 over 2 by the power of -2 times x by the power of 0times x by the power of 9"
Let's break it into parts.
"X by the power of 5 times y to the power of 6..."
This can be written as:
x^5*y^6
"... 2 by the power of -2 times x by the power of 0times x by the power of 9"
This can be written as:
2^(-2)*x^(0)*x^(9)
And we have the quotient between the first thing and the second thing, then the equation is:
[tex]\frac{x^5*y^6}{2^{-2}*x^0*x^9}[/tex]
And any number by the power of 0 is equal to 1, then:
x^0 = 1, then we can rewrite the equation as:
[tex]\frac{x^5*y^6}{2^{-2}*x^9}[/tex]
We can keep simplifying this.
We know that:
a^(-n) = (1/a)^(n)
Then:
2^(-2) = (1/2)^2 = 1/4
Then we get:
[tex]\frac{x^5*y^6}{2^{-2}*x^9} = \frac{x^5*y^6}{x^9}*4[/tex]
And we also know that:
a^n/a^m = a^(n - m)
Then:
[tex]\frac{x^5*y^6}{x^9}*4 = 4*y^6*\frac{x^5}{x^9} = 4*y^6*x^{5 - 9} = 4*y^6*x^{-4} = \frac{4*y^6}{x^4}[/tex]
And we can't simplify this anymore.

New York City is located about 40˚ north of the equator. If Earth's radius is about 4000 miles, approximately how many miles south would a plane need to fly from new York City to reach the equator?
Answer:
The answer is "2793 miles"
Step-by-step explanation:
In this firstly we convert degrees to radians, which can be defined as follows:
[tex]\to \theta =\frac{40^{\circ} \times \pi }{180^{\circ}}[/tex]
[tex]=\frac{ 2\pi }{9}[/tex]
Now calculating the distance:
[tex]=\frac{2\pi }{9} \times 4000\\\\= \frac{8000 \pi }{9}[/tex]
[tex]=\frac{8000\times 3.14 }{9}\\\\ = \frac{25120}{9}\\\\=2793 \ miles[/tex]

Firstly we'll factorize the terms:
45x³ = 3 * 3 * 5 * x * x * x
24x² = 2 * 2 * 2 * 3 * x * x
16x = 2 * 2 * 2 * 2 * x
The factor which is common in all three terms is:
