1/π is the radius of an expanding circle that grows twice as fast as its radius in linear units.

The size of a region on a surface is measured in area. Surface area refers to the area of an open surface or the border of a three-dimensional object, whereas area of a plane region or plane area refers to the area of a form or planar lamina.

Here,

The area of a circle is:  Ac  = π×r²     where r is the radius of the circle

If this area is expanding that mean Ac and r are a function of time and the speed is dA/dt and dr/dt can be found from the equation of the area

Then:

Ac = π×r²

dA/dt  = 2×π×r×dr/dt

According to the problem statement

dA/dt = 2×dr/dt

By substitution

2×dr/dt  =  2×π×r×dr/dt

Simplifying

1 = π×r  

and

r = 1/π

The Poisson law states that the probability of at least 2 different changes daily is 0.0263. Thus, 0.0263% of changes happen twice or more each day.

The mathematical method it explains for calculating probability calculates all the probabilities of something occurring in the setting of specific random events. A probability's proximity to the unit value and, conversely, its distance from zero can make one less comfortable in the outcome. The confidence level is based on how close the probability value is, which is calculated using a range from 0 and 1

Here,

The conditional probability function for X is the amount of times the incident occurs over a specific period of time.

In this experiment, the frequency, or x, at which an event occurs is counted.

The likelihood of the event happening throughout each period is equal.

The number of events in one period is independent of the number in other intervals.

The first step is to set the discrete stochastic process X to the number of website content updates.

Let's say that there are on average x content changes every day.

A bijective function is a function that is both one-to-one and onto, meaning that it assigns a unique output to each input, and every output in the codomain is assigned by some input in the domain.

If A has N elements and B has M elements, and we want to find the number of possible bijective functions from A to B, we can use the following formula:

Number of bijective functions = (Number of functions from A to B) / (Number of one-to-one functions from A to B)

The number of functions from A to B is given by the number of ways to assign each element of set A to set B, which is [tex]M^N[/tex].

The number of one-to-one functions from A to B is given by the number of ways to assign a unique element from set B to set A, which is[tex]M!/(M-N)![/tex]

If a metalworker has a metal alloy that is 30​% copper and another alloy that is 60​% copper. The amount of  kilograms of each alloy is:  20kg of 30% copper alloy must be combined with 30kg of 60% copper alloy to obtain 50 kg of 48% copper alloy.

Let a be the amount of 30% copper alloy and b be the amount of 60% copper alloys. The combined alloys must be 50 kilograms.

a + b = 50 kg

The total copper in the mixture:

0.30a + 0.60b = 0.48(50)

Substitute by making use of the first equation

0.30(50-b) + 0.60b = 24

15 -0.30b + 0.60b =24

0.30b= 9

Divide both side by 0.30b

b = 9/0.30

b = 30

The amount of 30% copper alloy needed is:

a= 50-b

a = 50 -30

a = 20

The act of charity is the selfless, voluntary assistance provided to those in need as a humanitarian act. There are several charitable ideologies, many of which are religious in nature.

In this problem, we can find the number of 11-packs of cookies by dividing the total number of cookies by the number of cookies in each pack.

We know that:

The number of 11 cookies pack can be determined by:

546 cookies / 11 cookies/pack = 49.63636...

An ordered pair is a set of two values, (x,y), that represents a point on a coordinate plane. To solve an ordered pair means to find the coordinates (x,y) of a point on a coordinate plane.

To solve two ordered pairs, you would need to know the coordinates of both points, and then you can graph them on a coordinate plane to visualize the relationship between the two points.

For example, if you have the ordered pairs (2,3) and (4,5), you can graph them on a coordinate plane with the x-axis and y-axis, where x represents the horizontal position and y represents the vertical position. The point (2,3) would be located at 2 on the x-axis and 3 on the y-axis, and the point (4,5) would be located at 4 on the x-axis and 5 on the y-axis.

Once you have plotted the points on a coordinate plane, you can use them to make a conclusion about the relationship between the two points, for example if they are in the same line, if the distance between them, if they form a slope, etc.

a) The probability that the randomly chosen injury took place on a Thursday would be 0.17.

b) The probability that the injury took place on a weekday (Monday through Friday) would be 0.84.

c) The probability that it took place on a Monday would be 21.4%.

What is the probability?

Probability is a measure of the likelihood of an event occurring. It is a number between 0 and 1, where 0 indicates that an event is impossible, and 1 indicates that an event is certain.

(a) To find the probability that the injury took place on a Thursday, we need to find the value of x in the probability table:

Day: Sunday Monday Tuesday Wednesday

Probability: 0.06 0.18 0.17 0.17

Day: Thursday Friday Saturday

Probability: x 0.15 0.09

The sum of the probabilities for each day must equal 1. So we can set up an equation to find x:

0.06 + 0.18 + 0.17 + 0.17 + x + 0.15 + 0.09 = 1

0.83 + x = 1

x = 0.17

The probability that the injury took place on a Thursday is 0.17.

(b) To find the probability that the injury took place on a weekday (Monday through Friday), we sum the probabilities for Monday, Tuesday, Wednesday, Thursday, and Friday:

0.18 + 0.17 + 0.17 + 0.17 + 0.15 = 0.84

The probability that the injury took place on a weekday is 0.84.

(c) Given that an injury took place on a weekday, we can use Bayes' Theorem to find the probability that it took place on a Monday. Let A be the event that the injury took place on a weekday, and B be the event that the injury took place on a Monday. Then:

P(B|A) = P(B and A) / P(A)

P(B and A) = P(B) = 0.18

P(A) = 0.84 (from (b))

So:

P(B|A) = 0.18 / 0.84 = 0.214 or 21.4%

The probability that the injury took place on a Monday, given that it took place on a weekday, is 21.4%.

Hence,

a) The probability that the randomly chosen injury took place on a Thursday would be 0.17.

b) The probability that the injury took place on a weekday (Monday through Friday) would be 0.84.

c) The probability that it took place on a Monday would be 21.4%.

Answer: We know that Tonia eats 2 meals each day, breakfast and dinner. We also know that the total calories for each breakfast are 500.

If Tonia ate breakfast for 5 days, the total calories for breakfast would be 500 x 5 = 2500 calories.

We know that the total calories she ate for 5 days was 9000 and the number of calories for breakfast is 2500.

The number of calories for dinner over 5 days is 9000 - 2500 = 6500 calories.

To find the average number of calories Tonia consumed for dinner each day over the 5 days, we need to divide the total number of calories for dinner by the number of days:

average number of calories = 6500 / 5 = 1300 calories per day.

So Tonia consumed an average of 1300 calories per day for dinner over the 5 days.

The rectangle has a length of 222 feet and a width of 150 feet.

A quadrilateral with parallel sides equal to one another and four equal vertices is known as a rectangle. It is also known as an equiangular quadrilateral for this reason.

Rectangles can also be referred to as parallelograms since their opposite sides are equal and parallel.

We know that the perimeter of a rectangle is the sum of all four sides. So in this case:

Perimeter = 2(length) + 2(width)

Given that the perimeter is 446 feet, we can set up the equation:

446 = 2(13x-1) + 2(9x+4)

On Simplifying, we get:

446 = 44x + 6

Now we can solve for x by subtracting 6 from both sides:

440 = 44x

Finally, dividing both sides by 44:

x = 10 feet

Now that we know the value of x, we can substitute it back into the expressions for the length and width:

Length = (13x-1) = (13(10)-1) = 129 feet

Width = (9x+4) = (9(10)+4) = 94 feet

Therefore, the rectangle has a length of 129 feet and a width of 94 feet.
