according to the law of large numbers

Answers

Answer:

In probability and statistics, the law of big numbers holds that as a sample size increases, its mean gets closer to the average of the entire population. This is because as the sample size increases, the sample becomes more representative of the population.

According to the law of large numbers, a large entity that is expanding quickly cannot continue doing so indefinitely. Often used as instances of this phenomenon are the largest blue chips, with market values in the hundreds of billions.

Two distinct subjects can be covered by the law of huge numbers. First, there are many topics to which the law of large numbers can be applied in statistical analysis. In order to acquire the necessary amount of data, it may not be practical to survey every member of a given population, but every additional data point has the potential to raise the probability that the result is an accurate representation of the mean.

Problem 1)
a) What is the possible number of microstates associated with tossing a coin N times and having it come up H times heads and T times tails?
b) For a series of 1000 tosses, what is the total number of microstates associated with 50% heads and 50% tails?
c) How less probable is the outcome that the coin will land 40% heads and 60% tails?

Answers

a) The number of microstates associated with tossing a coin N times and having it come up H times heads and T times tails is given by the binomial coefficient "N choose H" (or "N choose T", as H+T=N), which is equal to N!/(H! * T!)

b) For a series of 1000 tosses, with 50% heads and 50% tails, there are a total of "1000 choose 500" microstates. This is approximately 2.07*10²⁵ microstates.

c) The probability of getting a specific outcome when tossing a coin is given by the binomial probability mass function. The probability of getting 40% heads and 60% tails in 1000 tosses is given by (1000 choose 400)(0.4⁴⁰⁰)(0.6⁶⁰⁰) which is very less probable.

Coin Toss Microstates Probability

a) The number of microstates associated with a coin flip can be determined using combinatorics. The coin flip can have two possible outcomes: heads or tails. To calculate the number of microstates for N coin flips with H heads and T tails, we use the binomial coefficient formula "N choose H" (or "N choose T", as H+T=N), which is equal to N!/(H! * T!) where ! denotes factorial. This formula gives the number of ways to choose H heads out of N coin flips.

b) To calculate the total number of microstates for a series of 1000 tosses with 50% heads and 50% tails, we use the binomial coefficient formula "1000 choose 500". This is equivalent to (1000!/(500!500!)) which is approximately 2.0710²⁵ microstates.

c) The probability of getting a specific outcome when tossing a coin is given by the binomial probability mass function. The probability of getting 40% heads and 60% tails in 1000 tosses is given by (1000 choose 400)(0.4⁴⁰⁰)(0.6⁶⁰⁰) which is very less probable. We can calculate this using the binomial probability mass function which is ( n choose k ) * p^k * (1-p)^(n-k) where n is the number of trials, k is the number of successful outcomes, p is the probability of success in one trial, 1-p is the probability of failure in one trial.

The path of a firework can be represented by F9t=16^+92t+160
What is the maximum height of the firework?
How long did it take to reach its maximum height?

Answers

a) The maximum height of a firework is 292.25 feet.

b) The time required by a firework to reach its maximum height is 2.875 second.

How to determine the maximum height reached by a firework and its time needed

Herein we find the case of a firework being launched under free fall motion, that is, a vertical uniformly accelerated motion due to gravity, represented by following quadratic equation:

f(t) = - 16 · t² + 92 · t + 160

Where:

f(t) - Height, in feett - Time, in seconds

Part A - The maximum height can be found by modifying the quadratic equation into vertex form. This can be done by completing the square:

f(t) = - 16 · t² + 92 · t + 160

f(t) = - 16 · [t² - (23 / 4) · t - 10]

f(t) - 16 · (529 / 64) = - 16 · [t² - (23 / 4) · t + 529 / 64] + 160

f(t) - 292.25 = 16 · (t - 2.875)²

The firework reaches a maximum height of 292.25 feet.

Montana has campgrounds over 41 counties. Nevada has 637 campgrounds over 18 counties. If
Montana was proportional to Nevada in the number of campgrounds to counties, how many
campgrounds would Montana expect to have? Round to the nearest whole number.

Answers

Answer: In order to find the number of campgrounds that Montana would expect to have if it was proportional to Nevada in the number of campgrounds to counties, we need to determine the ratio of campgrounds to counties in Nevada and then apply that same ratio to Montana.

First, we'll find the ratio of campgrounds to counties in Nevada by dividing the number of campgrounds (637) by the number of counties (18): 637 / 18 = 35.389

Now we'll apply that same ratio to Montana by multiplying the number of counties in Montana (41) by the ratio of campgrounds to counties in Nevada: 41 x 35.389 = 1458.369

Rounding to the nearest whole number, we get 1458. So if Montana was proportional to Nevada in the number of campgrounds to counties, we would expect to find 1458 campgrounds in Montana.

The exact value of sin(x + y) is (1 - 2√6) /6. The 2nd option is the answer.

How to find the exact value of sin(x + y)?

We have sin(x) = -1/2 and cos(y) = -1/3

x is an angle in quadrant III, and y is an angle in quadrant II

For x:

Using trigonometric ratio

sin(x) = -1/2 (sin = opposite/hypotenuse)

adjacent = √(2²-(-1)²) = √3

cos(x) = (-√3)/2  (cos = adjacent/hypotenuse)

Note: adjacent in quadrant III is negative

For y:

Using trigonometric ratio

cos(y) = -1/3  (cos = adjacent/hypotenuse)

opposite = √(3²-(-1)²) = √8 = 2√2

sin(y) = (2√2)/3  (sin = opposite/hypotenuse)

Using trigonometric identity:

sin (x + y) = sin (x)·cos(y) + cos (x)·sin (y)

sin (x + y) = -1/2·(-1/3)  +  [(-√3)/2]·[(2√2)/3]

sin (x + y) = 1/6 - (√6)/3

sin (x + y) = (1 - 2√6) /6

From a 15-inch by 15-inch piece of metal, squares are cut out of the four corners so that the sides can be folded up to make a box. Let x represent the length of the sides of the squares, in inches, that are to be cut out. Express the volume of the box as a function of x.

Answers

By applying the formula of cuboid volume, the volume of the box can be expressed as 225x - 60x² + 4x³.

Cuboid is a 3-D shape formed by three pairs of rectangles (6 sides), 12 edges, and 8 vertices.

The volume of a cuboid can be calculated as follows:

Volume = length * width * height

Initially, we have a 15 x 15-inch piece of metal, then we cut out the four corners so that the sides can be folded up to make a box.

Now we have a shape as the attached image, where x represents the length of the sides of the squares that are to be cut out.

Thus, after the cutting, the length of the new side is 15 - 2x.

This value also represents the length and width of the box, whilst the height is x.

Now we can calculate the volume of the box:

Volume = length * width * height

             = (15 - 2x) * (15 - 2x) * x

             = (225 - 60x + 4x²) * x

             = 225x - 60x² + 4x³

Thus, the volume of the box can be expressed as 225x - 60x² + 4x³.

The remainder of the division is (x-3)(x+13)/x-7

How to determine the reminder

From the information given, we have that;

2 x squared plus 7 x minus 39 end quantity quantity x minus 7 end quantity

This is represented as;

2x² + 7x - 39/x - 7

Now, factorize the numerator

Find the pair factors of -78 that sum up to 7, then substitute the value, we have;

2x² + 13x - 6x - 39/x- 7

(2x² + 13x) - (6x-39)/x-7

Factor the common terms

x(x + 13) - 3(x + 13)/x-7

Then, we get;

(x-3)(x+13)/x-7

Hence, the value is (x-3)(x+13)/x-7

lian's truck has a 25 gallon tank and uses 0.05 gallon of gas for every mile driven.when creating a table for the function y=-0.05x + 25 ,lian argues that he can only use positive rational numbers for the input .is lian correct? justify your answer

Answers

Since it is possible to drive a fraction of a mile, so it will be appropriate to use fractions; however, it is not possible to drive a negative number of miles, so only positive rational numbers are appropriate.

How to interpret Linear equations?

A rational number is said to be positive if its numerator and denominator are both positive.

Now, we are told that lian's truck uses 0.05 gallon of gas for every mile driven. Thus;

Rate of consumption of gas = 0.05 gallons per mile

The function for number of gallons is;

y = -0.05x + 25

where;

x is number of miles

y is number of gallons

We can use a fraction for the number of miles because it is possible but then the number of miles must be positive rational numbers because number of miles cannot be negative.

For each of the following subsets of R3 determine whether it is a vector subspace of R3 or not. Justify your answer.

Answers

So, b) and e) are subspaces of R3, and a), c), and d) are not.

a) {(x,y,z) ∈R3 : x = 0} is not a subspace of R3, because it doesn't contain the zero vector (0,0,0) which is a requirement for a subspace. It's also not closed under scalar multiplication.

b) {(x,y,z) ∈R3: x + y = 0} is a subspace of R3, because it's closed under scalar multiplication and addition and it contains the zero vector (0,0,0).

c) {(x,y,z) ∈R3 : xz = 0} is not a subspace of R3, because it's not closed under scalar multiplication and it's not closed under addition

d) {(x,y,z) ∈ R3: y ≥0} is not a subspace of R3, because it's not closed under addition, it doesn't contain the zero vector (0,0,0) and it's not closed under scalar multiplication.

e) {(x,y,z) ∈ R3: x = y = z} is a subspace of R3 because it satisfies all the properties of a subspace, it is closed under addition, scalar multiplication, it contains the zero vector (0,0,0) and the negative of any vector in the set is also in the set. This set contains all the vectors that are multiples of (1,1,1) which forms a subspace.

So, b) and e) are subspaces of R3, and a), c), and d) are not.
