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.

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.

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

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

Since Dean ran 2.3 fewer kilometers than Sam. If Dean ran 6.8 km, the true statements about the distance which Sam ran are:

A. You know the difference in the distances the boys ran, so this is a subtraction problem.

E. The correct equation is s – 2.3 = 6.8.

In Mathematics, distance can be defined as the total amount of ground that is covered or travelled by a physical object (body) over a particular period of time and speed, irrespective of its direction, starting point or ending point.

Since Dean ran 6.8 km and 2.3 fewer kilometers than Sam, we can logically deduce that this is a subtraction problem. Assuming the variable s represent the distance which Sam ran, Sam's distance can be calculated as follows;

s – 2.3 = 6.8

s = 6.8 + 2.3

s = 9.1 kilometers.

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.

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

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.

Yes, cropping a picture and then using a scale factor to resize it is a two-step process.

The image is first cropped by subtracting 2 inches from the right side, altering the image's proportions.

The image is then enlarged using a scale factor of 1.5, which increases the image's dimensions by 1.5.

The final measurements of the image would be its original measurements less 2 inches (for cropping), then multiplied by 1.5. (for the resizing).

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.

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.
