There is a 1/3 chance, or around 0.333, that a randomly chosen passenger will have to wait longer than 10 minutes during one of these times.

What is probability?

Calculating the likelihood of experiments happening is one of the branches of mathematics known as probability. We can determine everything from the likelihood of receiving heads or tails when tossing a coin to the likelihood of making a research blunder, for instance, using a probability.

Since waiting times follow a uniform distribution on the interval from 0 to 15 minutes, the probability density function (PDF) is:

f(x) = 1/15, for 0 ≤ x ≤ 15

The probability that a randomly selected passenger has to wait more than 10 minutes is:

P(X > 10) = ∫10¹⁵ f(x) dx

P(X > 10) = ∫10¹⁵ 1/15 dx (since f(x) = 1/15 for 0 ≤ x ≤ 15)

P(X > 10) = [x/15]10¹⁵

P(X > 10) = (15 - 10)/15

P(X > 10) = 5/15

P(X > 10) = 1/3

Therefore, there is a 1/3 chance, or around 0.333, that a randomly chosen passenger will have to wait longer than 10 minutes during one of these times.

When b > 1, the function f (x) = bx represents exponential development. If 0 b 1, then the function f (x) = bx depicts exponential decay.

A relation is any subset of a Cartesian product.

As an illustration, a subset of is referred to as a "binary connection from A to B," and more specifically, a "relation on A."

A binary relation from A to B is made up of these ordered pairs (a,b), where the first component is from A and the second component is from B.

Every item in a set X is connected to one item in a different set Y through a connection known as a function (possibly the same set).

A function is only represented by a graph, which is a collection of all ordered pairs (x, f (x)).

Every function, as you can see from these definitions, is a relation from X.

Step-by-step explanation:

The point estimate of the population​ proportion, the margin of error is 0.365.

Margin of error is a statistic that expresses the amount of random sampling error in survey results. The larger the margin of error, the less confident people are that the poll results will reflect the overall census results. When the population is incompletely sampled and the resulting measure has a positive variance, the margin of error will be positive, i.e. the measures differ. The term margin of error is often used in non-survey contexts to refer to the error observed in the reporting of measured quantities.

According to the Question:

Given that:

Lower bound = 0.123​,

Upper bound = 0.607​,

Therefore , the solution of the given problem of number line comes out to be D, {-6}, {-3}, {5}, {-6, -3}, {-6, 5}, {-3, 5}.

The number line, a representation of real numbers in visual form, is a tool for teaching arithmetic. An energy line is depicted by it. Every actual number is used to represent a integer in the genuine number, or every exact number is used to represent a position. The separations between increments on a number line are identical. The numbers in a line can only be replied in the manner indicated by those numbers.

Here,

The set D = "-6, -3, 5" can be divided into a wide variety of subgroups, including:

Since the empty set is a subset of every set, D is a subset of the empty set.

The set D is a subgroup of itself.

=> Because -6 is an element of D, the collection "{-6}" is a subset of D.

=> Because -3 is an element of D, the collection "{-3}" is a subset of D.

=> Because 5 is an element of D, the collection "{5}" is a subset of D.

Due to the fact that both -6 and -3 are components of D, the set "{-6, -3}" is a subset of D.

=> Because both -3 and 5 are elements of D, the collection "{-3, 5}" is a subset of D.

Consequently, the subgroups of D are:, D, {-6}, {-3}, {5}, {-6, -3}, {-6, 5}, {-3, 5}.

The number of touchdowns are 4, field goals are 2 and safeties are 2 for the given system of equation.

A system of equations in algebra consists of two or more equations and looks for common answers to the equations. "A collection of equations fulfilled by the same set of variables is called a system of linear equations." Finding the values of the variables employed in a system of equations entails solving the set of equations. By keeping the equations balanced on both sides, we compute the values of the unknown variables. Finding the value of the variable that makes the condition of all the provided equations true is the primary goal when solving an equation system.

Let us suppose touchdowns = x.

Let us suppose field goals = y.

Let us suppose safeties = z.

Given that, they score point 8 times, thus:

x + y + z = 8

The total points scored are 38 thus,

7x + 3y + 2z = 38

Also,

x = (y + z)

Substituting the value of y + z in equation 1 we have:

x + x = 8

2x = 8

x = 4

Substitute the value of x in second equation:

7(4) + 3y + 2z = 38

28 + 3y + 2z = 38

3y + 2z = 10

Now, using x = (y + z). we have:

4 - z = y

Substitute the value of y:

3y + 2z = 10

3(4 - z) + 2z = 10

12 - 3z + 2z = 10

-z = -2

z = 2

Substitute the value of x and z:

x = (y + z)

4 = y + 2

y = 2

Hence, the number of touchdowns are 4, field goals are 2 and safeties are 2 for the given system of equation.

Step-by-step explanation:

it is known that carbon-14 has a half-life of approximately 5,700 years. This means that after   [tex]5,700[/tex] years, half of the original carbon-14 in a sample will have decayed.

Assuming that t is a function that relates the age of a plant fossil to the percentage of carbon-14 remaining, it can be expressed as:

[tex]t(c) = (ln(c/100) / ln(1/2)) \times 5,700 years[/tex]

where ln represents the natural logarithm.

Using this function, we can complete the statements as follows:

A fossil with 47% of its carbon-14 remaining is approximately 11,323 years old.

[tex]t(47) = (ln(47/100) / ln(1/2)) \times 5,700 ≈ 11,323 y[/tex]   years

A fossil that is [tex]7,000[/tex] years old will have approximately 28% of its carbon-14 remaining.

  [tex]t-1(7,000) = (ln(100/1) / ln(1/2)) \times 5,700 - 7,000 ≈ 23,200[/tex] years remaining

[tex]t-2(c) = (ln(c/100) / ln(1/2)) * 5,700[/tex]

[tex]c = 100 * e^(-7,000 / 5,700) ≈ 28% remaining.[/tex]

Therefore, In the second statement, we are using the inverse of the function t to find the percentage of carbon-14 remaining for a given age. We can write this as  [tex]t-1(7,000) = c,[/tex] where c is the percentage of carbon-14 remaining for a fossil that is   [tex]7,000[/tex] years old.

In geometry, the midpoint refers to the point that is exactly halfway between two given points, lines, or line segments. It is the point that divides a line segment into two equal parts. The midpoint is also known as the half-way point.

The midpoint can be found using a variety of methods, but the most common one is by using the midpoint formula, which is:

Midpoint = [(x1 + x2)/2, (y1 + y2)/2]

Where (x1, y1) and (x2, y2) are the coordinates of the two points.

The midpoint is an important concept in many mathematical and scientific fields, including physics, engineering, and computer graphics. It is often used to determine the center of mass, the point of balance, or the halfway point in a process or journey.

a. We can use the midpoint formula to find the midpoint of each side of the square:

Midpoint of AB: ((0+8)/2, (8+0)/2) = (4,4)

Midpoint of BC: ((0+0)/2, (-8+0)/2) = (0,-4)

Midpoint of CD: ((-8+0)/2, (0-8)/2) = (-4,-4)

Midpoint of DA: ((-8+0)/2, (0+8)/2) = (-4,4)

b. Connecting the consecutive midpoints of each side of a square creates a smaller square inside the original square. We can see this by observing that the midpoints of opposite sides of a square form the vertices of a smaller square.

The polygon formed by connecting the consecutive midpoints of each side of the square is a square.

c. If we repeat the process of connecting consecutive midpoints one more time, we will get a smaller square inside the square formed in part (b). This smaller square will have vertices at the midpoints of the sides of the square formed in part (b). We can see this by observing that the midpoints of the sides of a square form the vertices of a smaller square inside that square.

So the polygon that would result from connecting the consecutive midpoints of each side of the polygon determined in part (b) is another square.

The compound interest on birr 5006 at 5% for 4 years compounded annually​ is $1,078.82.

Compound interest is a type of interest that is calculated not only on the initial principal amount but also on the accumulated interest of previous periods.

In other words, the interest earned during each period is added to the principal amount, and the interest for the next period is calculated on the sum of the principal and the accumulated interest.

Given that:

First, convert R as a percent to r as a decimal

r = R/100

r = 5/100

r = 0.05 rate per year,

Then solve the equation for A

A = P(1 + r/n)^(nt)

A = 5,006(1 + 0.05/1)^(1*4)

A = 5,006(1 + 0.05)^(4)

A = $6,084.82

Compound interest =Amount - Principal

Compound interest = 6084.82 - 5006

Compound interest = $1,078.82

There are 8 ounces of cereal left in the box.

Dena ate 1/6 of the cereal, leaving 5/6 of the box for Joey.

Joey then ate 2/3 of the box, which is equivalent to (2/3) × (5/6) = 10/18 of the box.

The amount of cereal left in the box is therefore 18 - 10 = 8 ounces.

Therefore, there are 8 ounces of cereal left in the box.

To write the equation y = -13x + 102 in irrational form, we need to isolate x on one side of the equation.

First, let's subtract y from both sides to get:

-y + y2 = -13x + y2 + 102

Next, let's divide both sides by -13 to get:

x = (-1/13)y2 + (1/13)y - (102/13)

Therefore, the irrational equation of y2 = -13x + 102 is:

x = (-1/13)y^2 + (1/13)y - (102/13)

Raphael bought a 2/3 pound bag of sugar, and he used 3/4 of it for baking.

To find out how much sugar he used, we need to multiply the fraction of the bag that he used (3/4) by the weight of the bag (2/3 pounds):

(3/4) x (2/3) pounds

To simplify this fraction multiplication, we can cancel out the factor of 3 in the numerator and the denominator:
