Option B: The domain of the function is the set of all real numbers, Option C: the range of the function is the set of all non-negative real numbers, Option D: the graph has an intercept at (0, 0), and option G: the graph is symmetric with respect to the y-axis are correct statements about the graph.

There are only real numbers in the domain, or collection of x-values. This is so because x holds true for all numbers. The set of all non-negative real numbers is known as the range or set of y-values. This is due to the fact that every value we obtain for y is a positive real number. The graph's x-intercept and y-intercept, also known as the intersection point, are located at (0, 0). Instead of the other way around, the graph increases on the interval x>0 and decreases on the interval x<0. Instead of a maximum, the graph shows a minimum at (0, 0). The graph is symmetric with respect to the y-axis because it may be folded in half along that axis.

As per the question, the function described below is an example of a polynomial function since it is a function of a single independent variable that has been raised to an integer power.

4.1.1 and 4.1.3 are discrete variables and 4.1.2 is a continuous variable.

What are discrete and continuous variables?

Discrete variables are those that have distinct, countable values. A continuous variable can be assigned to any value that falls inside a range, which has an infinite number of possible values.

4.1.1 "I am fifty years old"

It is a discrete variable because age is represented in whole numbers.

4.1.2 "I can drink 400.5 ml of juice in a minute"

It is a continuous variable because the amount of juice is consumed every minute so, we can obtain values even in fraction.

4.1.3 "I have 2 brothers and 1 sister"

It is a discrete variable because the given value is countable.

Hence, 4.1.1 and 4.1.3 are discrete variables and 4.1.2 is a continuous variable.

Find the value of the 25th percentile. 25th percentile = second observation + decimal portion of L25(third observation - second observation) = 24 + 0.25 ( ____ – 24) =

Answers

The value of the 25th percentile for this data set is 26.25. This means that 25% of the data is below 26.25 and 75% of the data is above 26.25

The 25th percentile, also known as the lower quartile, is a value that separates the lowest 25% of the data from the rest of the data. To find the 25th percentile of an ordered data set, we first need to determine the position of the 25th percentile, which can be calculated using the formula:

position = (n+1) * p

where n is the number of observations in the data set and p is the percentile (in decimal form). In this case, n = 8 and p = 0.25. Put values:

position = (8+1) * 0.25 = 2.25

Since the position is not a whole number, we know that the 25th percentile falls between the second and third observations in the data set. In this case, the second observation is 24 and the third observation is 27. To find the exact value of the 25th percentile, we use the formula:

value = L + (position - i) * h

where L is the value of the lower observation, i is the integer part of the position, and h is the difference between the two observations. In this case, L = 24, i = 2, and h = 27 - 24 = 3. Put values:

value = 24 + (2.25 - 2) * 3 = 24 + 0.75 * 3 = 24 + 2.25 = 26.25

The perimeter of a rectangle is 430 meters. Express the area A as a function of the length L, and state the domain of this function

A(L) = ? m²

Answers

ANSWER -

Let L be the length of the rectangle and W be the width. The perimeter is given by 2(L + W) = 430. Solving for W, we have W = (430 - 2L)/2. The area A is given by the product of the length and the width:

A(L) = L * W = L * (430 - 2L)/2 = 215L - L^2.

So the area A is a function of the length L with the equation A(L) = 215L - L^2.

The domain of this function is the set of all real numbers L such that the width W is positive, i.e., 0 < W < ∞. This implies that 0 < 215 - 2L < ∞, or 0 < 215 < 2L. Hence, the domain of the function A is L > 107.5.

Answer:

A(L) = - L²  + 215L

Domain
0 < L < 215

or

(0, 215) in interval notation

Step-by-step explanation:

Let  L represent the length and W the width

Perimeter of a rectangle = 2(L+W) and is given as 430 meters

Therefore 2(L + W) = 430

L + W = 430/2
L + W = 215

W = 215-L

The area A is given by L x W

Substituting for W in terms of L this becomes

A = L x(215 - L)

A = 215L - L²

which can be expressed as a function of in the form
A(L) = 215L - L² or in standard form(highest degree first)

A(L) = - L²  + 215L

The domain of this function are the values of L which result in a defined , real value for A

Without restrictions, the domain for L is -∞ < L < ∞. However real world facts coming into play

1. Area cannot be zero
So A(L) > 0 (upper bound on area)

-L² + 215L > 0

-L² > - 215L Move 215L to right side

L² < 215L   (dividing by -1 changes signs of variables and also inequality)

L < 215      (divide by L both sides)

2. Length cannot be negative
So lower bound on L is L > 0

Together the domain is
0 < L < 215

Step-by-step explanation:

Perimeter of rectangle = Perimeter of triangle

= {2 × (Length + Width)} = Sum of all three sides

= {2 × [(2x) + (x + 12)]} = [(4x) + (2x) + (x + 3)]


The parenthesis are expanded using the Distributive Law:
= {2 × [2x + x + 12]}  = [4x + 2x + x + 3]

= {2 × [3x + 12]} = [7x + 3]
= 6x + 24 = 7x + 3

Bring all the like terms together and isolate x:

= 24 - 3 = 7x - 6x

= 21 = x

∴x = 21


Substitute this calculated value of x to determine the perimeter of rectangle:

6x + 24

= 6(21) + 24

= 126 + 24

= 150 units

Turning yards into feet

Answers

To convert yards to feet we multiply the given value by 3.

How is this determined?

A yard is one linear yard. "Yd" is the yard symbol. It is equivalent to 36 inches or 3 feet. 1 yard equals 0.9144 metres in metres when measured in metres. Both the imperial and US customary systems of measuring use this unit. The most common use of yards is to measure the length of a field, such a sports field.

A foot can also be used to measure length. The letter "ft" stands for the foot. Twelve inches and one third of a yard make up one foot. Additionally, one foot is equal to 0.3048 metres. We must divide the provided value by 3.281 to translate the given value from feet to metres. In aviation and elevation, the foot is typically used to measure height or altitude. The height of a person is also expressed in feet and inches.

The study and application of numbers in all other fields of mathematics are covered in the area of mathematics known as arithmetic operations. Addition, subtraction, multiplication, and division are included in the basic operations.

Given the thickness of plate 1 = 7/8 inches

the thickness of plate 2 = [tex]1\frac{1}{4}[/tex] inches = 5/8 inches

total thickness of both plates = 7/8 + 5/4

5/4 is equaivalent to (5*2)/(4*2) = 10/8

Answers

An equation of a line in a slope-intercept format that is parallel to

y = (1/2)x - 3 line and goes through the point (4, 2) is y = (1/2)x

What are lines and their slopes?

We know lines have various types of equations, the general type is

Ax + By + c = 0, and the equation of a line in slope-intercept form is

y = mx + b.

Where slope = m and b = y-intercept.

the slope is the rate of change of the y-axis with respect to the x-axis and the y-intercept is the (0,b) where the line intersects the y-axis at x = 0.

We know parallel lines have equal slopes.

The equation of the line given is y = (1/2)x - 3 and our required equation is parallel to it and passes through (4, 2).

So, 2 = (1/2)(4) + b.

2 = 2 + b.

b = 0.

The students in Class 6 vote to pick a class captain. The choice is Anton, Eva, Kofi or Petra. Anton gets 0.2 of the votes. Eva gets 10% of the votes. Petra gets of the votes. Kofi gets 9 votes. How many students are in class 6?​

Answers

Answer:

Step-by-step explanation:

Let's say there are "x" students in class 6.

Since Anton got 0.2 of the votes, he got 0.2 * x votes.

Eva got 10% of the votes, which is equal to 0.1 * x votes.

Petra got 0.3 of the votes, which is equal to 0.3 * x votes.

Kofi got 9 votes.

So, the total number of votes in class 6 is x.

By adding up the number of votes each candidate received, we can write an equation:

0.2x + 0.1x + 0.3x + 9 = x

Simplifying the equation:

0.6x + 9 = x

Subtracting 0.6x from both sides:

9 = 0.4x

Dividing both sides by 0.4:

x = 22.5

Since the number of students must be a whole number, we round up to the nearest whole number:

x = 23

So there are 23 students in Class 6.
