The number line is represented by the inequality -

Option C - |2x - 1| ≥ 9

What is an inequality?

In Algebra, an inequality is a mathematical statement that uses the inequality symbol to illustrate the relationship between two expressions. An inequality symbol has non-equal expressions on both sides. It indicates that the phrase on the left should be bigger or smaller than the expression on the right, or vice versa.

The number line indicates two filled circles which suggests the inequality contains (≤,≥) symbols and is inclusive of range.

The first inequality will be x ≤ -4 since the value is starting from -4 and moving towards negative infinity.

Similarly, the second inequality will be x ≥ 5 since the value is starting from 5 and moving towards positive infinity.

The compound inequality that results in same is -

|2x - 1| ≥ 9

Apply the absolute rule -

2x - 1 ≥ 9 or 2x - 1 ≤ -9

Solve the inequality -

2x - 1 ≥ 9 or 2x - 1 ≤ -9

2x - 1 + 1 ≥ 9 + 1 or 2x - 1 + 1 ≤ -9 + 1

2x ≥ 10 or 2x ≤ -8

x ≥ 5 or x ≤ -4

Therefore, the inequality is |2x - 1| ≥ 9.

The number of possible outcomes in the sample space of a wireless garage door opener with 16 switches can be determined using the concept of combination is 1.

Combination is a mathematical concept that refers to the number of ways that a set of objects can be selected from a larger set without regard to their order.

To determine the number of possible outcomes in the sample space, we can use the concept of combination. In this case, the objects are the 16 switches, and the larger set is the set of all possible settings for these switches (up or down).

To calculate the number of possible combinations, we can use the formula for combination, which is:

ⁿCₓ = n! / (x! * (n - x)!)

where n is the total number of objects (16 switches), and x is the number of objects selected (in this case, also 16 switches). The exclamation mark (!) represents the factorial function, which is the product of all positive integers up to and including the given integer.

Using this formula, we can calculate the number of possible combinations as follows:

=> 16! / (16! x (16 - 16)!)

=> 16! / (16! x 0!)

=> 1

Therefore, the sample space of possible codes for a wireless garage door opener with 16 switches is 1.

In the 5-hour trip from Dallas to Houston, a Houston-bound bus passes 10 Dallas-bound buses on the highway

The first step to solving this problem is to understand the time it takes for each bus to travel from one city to another. We know that the trip from Dallas to Houston takes 5 hours.

Now, let's use the concept of time to determine how many Dallas-bound buses a Houston-bound bus passes on the highway. We know that buses from Dallas to Houston leave every hour on the hour and buses from Houston to Dallas leave every hour on the half hour. This means that a Houston-bound bus leaves at 1:30 pm, 2:30 pm, 3:30 pm, and so on.

If a Houston-bound bus leaves at 1:30 pm, it will pass the first Dallas-bound bus that left at 1:00 pm after 2.5 hours. This is because the distance between the two cities is the same, and both buses are traveling at the same speed. Therefore, the Houston-bound bus will have traveled half of the distance in 2.5 hours, and it will pass the Dallas-bound bus on the highway.

Similarly, if a Houston-bound bus leaves at 2:30 pm, it will pass the second Dallas-bound bus that left at 2:00 pm after 2.5 hours. This process continues for every Houston-bound bus that leaves on the half hour.

In other words, for every hour that passes, a Houston-bound bus passes two Dallas-bound buses on the highway. Therefore,

What is the area of any geometrical shape?

The area of a geometrical shape is a measurement of the extent of a two-dimensional surface. It is the measure of the amount of space inside the shape, which can be expressed in square units, such as square inches, square feet, or square meters.

Rectangle: area = length x width

Trapezoid: area = ((base1 + base2) / 2) x height

To find the area of the floor, we need to split the shape into two parts: a trapezoid on top and a rectangle on bottom.

The area of the trapezoid is: (33 + 19) / 2 * 14 = 385 square feet

The area of the rectangle is: 33 * 28 = 924 square feet

The total area is: 385 + 924 = 1309 square feet

Multiplying by the cost per square foot, we get:

1309 * 1.67 = 2184.03

Hence, the cost to wax the floor will be $2,184.03.

The twins are 6 years old, and the oldest sister is 13 years old (since they were born seven years after their older sister).

7.3% of women under the age of 35. 6.9% of females aged 35 to 37. 6.8% of women aged 38 to 40 were female. 5.1% of females aged 41 to 42.

Starting out, let's assign some variables.

Let x represent the sister's older sister's age in years.

The twins' age is then x – 7. (since they were born seven years after their older sister).

We are told that the product of the three siblings' ages is 2693 more than the sum of their ages. This can be expressed algebraically as:

x(x - 7)(x - 7) = x + (x - 7) + (x - 7) + 2693

Simplifying this equation gives:

x³ - 21x² + 98x - 2693 = 0

We can see that x = 13 is a root of the equation, since:

13³ - 21(13)² + 98(13) - 2693 = 0

This means that (x - 13) is a factor of the equation.

We can use polynomial division or synthetic division to divide the equation by (x - 13) and obtain a quadratic equation:

x² - 8x + 207 = 0

The solutions of this quadratic equation are:

x = (8 ± sqrt(8² - 4(1)(207))) / 2 = 4 ± sqrt(241)

Since x represents the age of the older sister, which must be a positive integer, the only valid solution is:

The interior angle of a parallelogram is proportional to the measure of another angle with a ratio of 0.25:1.

A parallelogram is a four-sided flat shape that has opposite sides that are parallel and equal in length. The sum of the interior angles of a parallelogram is equal to 360 degrees. If the measure of one interior angle is 0.25 times the measure of another angle, this means that there is a proportionate relationship between the two angles. To find the measure of the second angle, we can use the formula:

Angle 2 = (Angle 1) / 0.25

For example, if Angle 1 is 100 degrees, then Angle 2 is 100 / 0.25 = 400 degrees. This means that if one angle measures 100 degrees, the other angle measures 400 degrees. The sum of the two angles is 500 degrees, which is still less than the total sum of interior angles in a parallelogram, which is 360 degrees.

The amount that needs to be invested at the interest rate of 4% compounded continuously is P = $8932.461.

Compound interest, also known as interest on principal and interest, is the practise of adding interest to the principal amount of a loan or deposit. It occurs when interest is reinvested, or added to the loaned capital rather than paid out, or when the borrower is required to pay it, so that interest is generated the next period on the principal amount plus any accumulated interest. In finance and economics, compound interest is common.

Given that the interest is compounded continuously.

For the given situation the formula of compound interest is:

[tex]A = Pe^{rt}[/tex]

where, A is the amount = $12300

P is the principal amount

r is the rate = 4% = 0.04

t is the time = 8 years

Substituting the values we have:

[tex]12300 = Pe^{(0.04)(8)}\\\\P = \frac{12300}{e^{(0.04)(8)}} \\\\P =8932.461[/tex]

52 students passed only one subject

Let's use the following variables to represent the number of students who passed each subject:

P(Ga): the number of students who passed Ga

P(Fante): the number of students who passed Fante

From the problem statement, we know that:

P(Ga) = P(Fante) + 6, since the number of students who passed Ga is 6 more than the number who passed Fante

P(Ga ∩ Fante) = 8, since 8 students passed both subjects

P(Ga ∪ Fante) = 60, since every student passed at least one subject

We want to find the number of students who passed only one subject, which is equal to the total number of students who passed Ga minus the number of students who passed both subjects, plus the number of students who passed Fante but not Ga. In symbols:

P(Ga) - P(Ga ∩ Fante) + (P(Fante) - P(Ga ∩ Fante))

Substituting the values we know:

(P(Fante) + 6) - 8 + (P(Fante) - 8)

Simplifying:

2P(Fante) - 10

We also know that P(Ga) + P(Fante) - P(Ga ∩ Fante) = P(Ga ∪ Fante) = 60.

Substituting the values we know:

P(Ga) + P(Fante) - 8 = 60

P(Ga) + P(Fante) = 68

Substituting P(Ga) = P(Fante) + 6:

2P(Fante) + 6 = 68

2P(Fante) = 62

P(Fante) = 31

The probability that the actor will get his lines straight for the first time on the fourth attempt is 0.0864, rounded to three decimal places.

Probability can be defined as the ratio of favorable outcomes to the total number of events.

Here,
The probability that the actor will get his lines straight on any one take is 0.40. This means that the probability of him not getting his lines straight on any one take is 1 - 0.40 = 0.60.

P(getting lines straight on 4th attempt)
= P(not getting lines straight on 1st, 2nd, or 3rd attempt) x P(getting lines straight on 4th attempt)

P(not getting lines straight on any one attempt) = 0.60

P(not getting lines straight on 1st, 2nd, or 3rd attempt) = 0.60 x 0.60 x 0.60 = 0.216

P(getting lines straight on 4th attempt) = 0.40

P(getting lines straight for the first time on the fourth attempt) = P(not getting lines straight on 1st, 2nd, or 3rd attempt) x P(getting lines straight on 4th attempt)
= 0.216 x 0.40 = 0.0864

The trustworthiness of the prediction depends on the specific data and relationship between the predictor and response variable, and must be evaluated on a case-by-case basis.

To determine the trustworthiness of a prediction using a simple linear regression equation, we need to assess the degree of linearity and the strength of the relationship between the predictor and the response variable.

If the relationship between the predictor and response is linear, the simple linear regression model is appropriate, and if the relationship is strong, the predictions will be more trustworthy.

So, if we have four values for the predictor, we would need to evaluate the scatterplot of the predictor and response variable to determine the linearity and strength of the relationship.

If the scatterplot shows a clear and strong linear relationship between the predictor and the response variable, with a relatively small amount of scatter around the line of best fit, then we can be more confident that our predictions using the simple linear regression equation will be trustworthy.

On the other hand, if the scatterplot shows a weak or non-linear relationship, or a high amount of scatter around the line of best fit, then the predictions using the simple linear regression equation may not be as trustworthy.

Therefore, the trustworthiness of the prediction depends on the specific data and relationship between the predictor and response variable, and must be evaluated on a case-by-case basis.

The total volume of compost required for 16 bowls is 67,493.33 cm³

The total weight of compost required for 16 bowls is 155,906.67 gm

The total amount of polythene required for 16 bowls is: 6400π cm²

(i) The volume of compost required per bowl can be calculated as follows:

V = (4/3)πr^3, where r is the radius of the sphere

The radius of each bowl can be calculated as:

r = (d/2) - t, where d is the diameter (21 cm) and t is the thickness (0.5 cm)

So, r = (21/2) - 0.5 = 10 cm

Plugging the value of r into the formula for volume:

V = (4/3)πr^3 = (4/3)π * 10^3 = 4186.67 cm³

The total volume of compost required for 16 bowls is:

16 * 4186.67 = 67,493.33 cm³

The total weight of compost required for 16 bowls is:

67,493.33 cm³ * 2.31 gm/cm³ = 155,906.67 gm

(ii) To find the total amount of polythene required to cover the outer surface of 16 bowls, we first need to calculate the surface area of one bowl.

The surface area of a sphere can be calculated as follows:

A = 4πr^2

Plugging the value of r into the formula for surface area:

A = 4πr^2 = 4π * 10^2 = 400π cm²

First, the formula for the circumference of a circle is 2pi(r), so plugging in 14 yards, you get 28pi roughly 88 but for an actual answer 87.9645943005

Answer:

First, we need to find the area of Site A and Site B. The area of a rectangle is found by multiplying its length and width, so:

Site A: 60 m x 40 m = 2400 m^2

Site B: 45 m x 40 m = 1800 m^2

Next, we need to find the perimeter of each site, which is the distance around the edges of the rectangle. The perimeter is found by adding up the lengths of all four sides, so:

Site A: 2 x (60 m + 40 m) = 2 x 100 m = 200 m

Site B: 2 x (45 m + 40 m) = 2 x 85 m = 170 m

Finally, to find the total amount of rope needed, we add up the perimeters of both sites:

200 m + 170 m = 370 m

So, we need a total of 370 meters of rope to rope off both sites.

a) The probability that no one reports the loss or theft of their credit cards is 0.0498.

b) The probability that every credit card is lost or stolen is practically zero.

c) The probability that exactly six people report the loss or theft of their cards is 0.1042

d) The probability that at least nine people report the loss or theft of their cards is 0.2142

a. To calculate the probability that no one reports the loss or theft of their credit cards, we can use the Poisson distribution with an average of λ = 0.02% * 15,000 = 3.

The probability that no one reports the loss or theft of their credit cards is:

P(X = 0) = e^(-λ) * (λ^0 / 0!) = e^(-3) * (1 / 1) = 0.0498 or approximately 5%.

b. The probability that every credit card is lost or stolen is:

P(X = 15000) = e^(-λ) * (λ^15000 / 15000!)

Since λ is very small, the probability of all 15000 credit cards being lost or stolen in a month is practically zero.

c. To calculate the probability that six people report the loss or theft of their cards, we again use the Poisson distribution with an average of λ = 3.

The probability that exactly six people report the loss or theft of their cards is:

P(X = 6) = e^(-λ) * (λ^6 / 6!) = e^(-3) * (3^6 / 720) = 0.1042 or approximately 10.4%.

d. To calculate the probability that at least nine people report the loss or theft of their cards, we need to sum the probabilities for X = 9, 10, 11, ..., 15, since there are only 15,000 credit cards in total.

The probability that at least nine people report the loss or theft of their cards is:

P(X >= 9) = Σ(i=9 to 15) P(X = i) = Σ(i=9 to 15) e^(-λ) * (λ^i / i!)

This is a tedious calculation to do by hand, but we can use a calculator or software to find that P(X >= 9) is approximately 0.2142 or 21.42%.
