By answering the above question, we may state that Debra would thus function need to travel 150 miles for the price of the two plans to be the same.

Mathematicians research numbers, their variants, equations, forms, and related structures, as well as possible locations for these things. The relationship between a group of inputs, each of which has a corresponding output, is referred to as a function. Every input contributes to a single, distinct output in a connection between inputs and outputs known as a function. A domain, codomain, or scope is assigned to each function. Often, functions are denoted with the letter f. (x). The key is an x. There are four main categories of accessible functions: on functions, one-to-one capabilities, so many capabilities, in capabilities, and on functions.

The starting charge and the cost per mile would be added together for the first plan's total cost:

Costs for plan 1 total 47.96 plus 0.19x.

The first charge and the cost per mile would be added together for the second plan's total cost:

Plan 2's overall cost is 53.96 plus 0.15x.

Set the two total cost expressions equal to one another and solve for x to get how many miles Debra would need to go for the two plans to be the same in price:

Answer:

What is the unit price of each battery in each package?

To find the unit price of each battery in each package, we need to divide the total cost of each package by the number of batteries in each package.

For the package of 8 count AA batteries:

Total cost: $6.16

Number of batteries: 8

Unit price = Total cost / Number of batteries = $6.16 / 8 = $0.77 per battery

For the package of 20 count AA batteries:

Total cost: $15.20

Number of batteries: 20

Unit price = Total cost / Number of batteries = $15.20 / 20 = $0.76 per battery

Therefore, the unit price of each battery in the package of 8 count AA batteries is $0.77, and the unit price of each battery in the package of 20 count AA batteries is $0.76.

Neither of the given points is a solution to the system of linear inequalities.

What does solution to the system of linear inequalities mean ?

A system of linear inequalities is a set of two or more linear inequalities with the same variables. This system consists of two linear inequalities, each involving the variables x and y, and each inequality uses one of the inequality symbols.

The solution to a system of linear inequalities is the set of values for the variables that satisfy all the inequalities in the system simultaneously. This solution can be represented graphically as the region of the coordinate plane that satisfies all the inequalities in the system.

Check the given points whether they are solutions to the system of linear inequalities or not :

Substitute the x and y values of each point into both inequalities and check if they are true.

(a) (-4,1) :

y ≤ -3x - 2

1 ≤ -3(-4) - 2

1 ≤ 10

This is false, so (-4,1) is a not solution to the first inequality.

y > x - 2

1 > -4 - 2

1 > -6

This is true, so (-4,1) is a solution to the second inequality.

Since (-4,1) is a solution to only one of the inequalities and not both, it is not a solution to the system of linear inequalities.

(b) (2,2):

y ≤ -3x - 2

2 ≤ -3(2) - 2

2 ≤ -8

This is false, so (2,2) is not a solution to the first inequality.

y > x - 2

2 > 2 - 2

2 > 0

This is true, so (2,2) is a solution to the second inequality.

Since (2,2) is a solution to only one of the inequalities and not both, it is not a solution to the system of linear inequalities.

Therefore, the length of the arc intercepted by the central angle is 56.52 cm (rounded to two decimal places).

In geometry, an arc is a part of a circle. Specifically, it is a portion of the circumference of a circle. An arc can be defined by two endpoints and all the points on the circle's circumference between those endpoints. Arcs are commonly measured in degrees, just like angles. A full circle has 360 degrees, so a semicircle has 180 degrees, and so on. The length of an arc depends on the size of the circle and the size of the central angle that intercepts it. Arcs are important in many applications of geometry, such as in navigation, architecture, and engineering. They are also used in trigonometry and calculus to study functions that involve circular or periodic behavior.

Here,

We can use the formula for the length of an arc of a circle to find the length of the arc intercepted by a central angle. The formula is:

Length of arc = (Central angle / 360) x (2 x π x radius)

where π (pi) is a mathematical constant approximately equal to 3.14.

In this case, the central angle measures 270 degrees and the radius of the circle is 12 cm. We can substitute these values into the formula to get:

Length of arc = (270 / 360) x (2 x π x 12)

Length of arc = (3/4) x (2 x 3.14 x 12)

Length of arc = 0.75 x 75.36

The length of AC is 12.

Arithmetic operations are the basic part of mathematics which combines the basic operations like addition, subtraction, multiplication and division.

Given is a line.

A, B, C, D, E and F are equally spaced on the line.

Given that, EF = 2x

This means that distance between each of the point is 2x.

AB = 2x, BC = 2x, CD = 2x, and DE = 2x

Given BE = 10x - 12

BE = BC + CD + DE

So, 10x - 12 = 6x

10x - 6x = 12

4x = 12

The equation of the tangent line to the curve sin(x+y) = 4x - 4y at the point (π,π) is y = (-4/5)x + (8/5) + π.

Step-by-step explanation:

o find the equation of the tangent line to the curve sin(x+y) = 4x - 4y at the point (π,π) using implicit differentiation, we can follow these steps:

Differentiate both sides of the equation with respect to x:

cos(x+y) * (1 + dy/dx) = 4 - 4dy/dx

Simplify by grouping the terms with dy/dx on one side and the rest on the other side:

cos(x+y) * (1 + dy/dx) + 4dy/dx = 4

Substitute x = π and y = π, since we want to find the equation of the tangent line at the point (π,π):

cos(2π) * (1 + dy/dx) + 4dy/dx = 4

Simplify:

-5dy/dx = 4 - cos(2π)

dy/dx = -4/5

Use the point-slope form of the equation of a line to write the equation of the tangent line:

y - π = (-4/5)(x - π)

Simplify:

y = (-4/5)x + (8/5) + π

The equation of the tangent line to the curve sin(x+y) = 4x - 4y at the point (π,π) is y = (-4/5)x + (8/5) + π.

Answer:

It seems like there is a mistake in the variable provided. The variable mentioned is "Gender" but the data provided is about "Age" and "f" (frequency). Assuming that "f" is the frequency of participants at each age, here are the answers to your questions:

For the variable "f", the most appropriate measure of central tendency would be the mode, which represents the most frequently occurring value. For the variable "Age", the most appropriate measure of central tendency would be the median, as it is less affected by outliers than the mean.

Mode = 8; Median = 11; Mean = 10.11 (rounded to two decimal places)

Range = 15 - 7 = 8; Variance = 8.99 (rounded to two decimal places); Standard deviation = 2.99 (rounded to two decimal places)

To calculate the age range that reflects 68% of the sample, we need to find the mean age and the standard deviation. The mean age is 10.11, and the standard deviation is 2.99. 68% of the data falls within one standard deviation of the mean. Using the empirical rule, we can say that the ages of participants that reflect 68% of the sample are between (10.11 - 2.99) and (10.11 + 2.99), which is between 7.12 and 13.10.

Step-by-step explanation:

Answer:

Step-by-step explanation:

Since the variable Gender is not given in the data, we cannot compute any measure of central tendency for it. For the variable Age, the most appropriate measure of central tendency would be the mode, since all the observations have the same value for this variable.

To calculate the mode, median and mean for Age, we can first arrange the data in ascending order of age:

7, 2

8, 2

9, 0

10, 1

11, 1

12, 1

13, 1

14, 1

15, 1

The mode is the most frequently occurring value, which is 1 for all ages. The median is the middle value when the data is arranged in ascending order. Since there are 9 observations, the median is the average of the 5th and 6th values, which are 12 and 13. So, the median is (12+13)/2 = 12.5. The mean is the sum of all the values divided by the number of observations, which is:

(72 + 82 + 90 + 101 + 111 + 121 + 131 + 141 + 15*1) / 9 = 11.44 (rounded to two decimal places)

Therefore, the mode is 1, the median is 12.5 and the mean is 11.44.

To calculate the range, variance and standard deviation for Age, we can use the following formulas (assuming the data is a population):

Range = maximum value - minimum value = 15 - 7 = 8

Mean = 11.44 (computed in step 2)

Variance = Σ(x - μ)^2 / N, where μ is the mean, x is each value, and N is the number of observations. Plugging in the values, we get:

Variance = [(7-11.44)^2 + (8-11.44)^2 + (9-11.44)^2 + (10-11.44)^2 + (11-11.44)^2 + (12-11.44)^2 + (13-11.44)^2 + (14-11.44)^2 + (15-11.44)^2] / 9 = 5.72 (rounded to two decimal places)

Standard deviation = square root of variance = √5.72 = 2.39 (rounded to two decimal places)

Therefore, the range is 8, the variance is 5.72, and the standard deviation is 2.39.

Since the data is approximately normally distributed, we can use the empirical rule to estimate the ages that reflect 68% of the sample. According to the empirical rule, 68% of the data falls within one standard deviation of the mean. So, we can compute the lower and upper limits of this range by subtracting and adding one standard deviation from the mean, respectively:

Lower limit = mean - standard deviation = 11.44 - 2.39 = 9.05 (rounded to two decimal places)

Upper limit = mean + standard deviation = 11.44 + 2.39 = 13.83 (rounded to two decimal places)

Therefore, the ages of participants that reflect 68% of the sample are between 9.05 and 13.83 years old.

Therefore, the area of the base of the aquarium is 5760 square centimeters.

Area is a measure of the amount of space inside a two-dimensional (2D) shape or figure. It is usually measured in square units, such as square meters (m²) or square centimeters (cm²). The area of a shape is calculated by multiplying the length of one side or dimension of the shape by the length of another side or dimension. The resulting value represents the total number of square units that are contained within the shape. Area is an important concept in mathematics and is used in various fields, such as geometry, physics, and engineering. It helps in measuring and comparing the sizes of shapes and figures, and in determining how much material is needed to cover or fill a certain area.

Here,

The area of the base can be calculated using the dimensions of the aquarium.

Let's assume that the aquarium has a rectangular base with length L, width W, and height H. Then, the area of the base of the aquarium can be calculated as:

Area of base = Length x Width = L x W

If Monica measured the length and width of the base, we can use those measurements to calculate the area of the base. If not, we'll need to make additional assumptions or measurements.

Assuming we have the length and width of the base, we can calculate the area as follows:

Area of base = Length x Width

A circle is formed by all points in a plane that are at a particular distance from the centre. The radius of a circle is the separation between any point on the circle and its center.

The product of the measures of the secant segment and its external secant segment equals the square of the measure of the tangent segment if a tangent segment from a location outside the circle, secant segments are drawn.

In the circle shown, if

AB=6cm

AC=4cm and

CD=x?

AC×AD=[tex]AB^{2}[/tex]

4(4+x)=[tex]6^{2}[/tex]

4+x=36/4

x=5

Hence, The length of segment in the given circle x is 5cm.
