What do you notice about the absolute value of the
difference between the two numbers of -5 and -1
Mark all the relative minimum points in the graph.
Please help I don't understand what to do.
Answer:
Step-by-step explanation:
The thing to remember is that absolute can be relative but relative can't be absolute. In other words, absolute min is the very lowest point on the graph and there's usually only one (unless there are 2 absolute mins that have the same y value) while relative mins can occur at several points on a graph. That means that the only relative min point on the graph occurs at (-3, 4); the absolute min occurs at (5, -6).

What is the value of a in the given figure
Answer:
soln
let one side be c
let another side be d
then
40=d(vertically opposite angle)
5a =c(vertically opposite angle)
again
c+90=180(being linear pair)
or, c=180-90
therefore, c=90
finally
let c be a
5a=5×90
=450
Answer:
a = 10
Step-by-step explanation:
CF is a straight line , so the 3 angles on it sum to 180° , then
∠ BOA = 180° - (90 + 40)° = 180° - 130° = 50°
∠ DOE = ∠ BOA ( vertical angles ) , then
5a = 50 ( divide both sides by 5 )
a = 10
.The conversion of square feet to square yards can be represented by direct variation. Three square yards are equivalent to 27 square feet. Let y represent the number of square yards and x the number of square feet. Then y varies directly with x.
What is the constant of variation?
What is the equation representing the direct variation?
Answer:
The constant of variation is 1/9
The equation representing the direct variation is y/x= 1/9
Step-by-step explanation:
In direct variation, y/x=k denotes the equation, with k being the constant of variation. Here, y is the number of square yards and x is the number of square feet. Therefore, as we know that 27 square feet = 3 square yards, we can write one point (x₁, y₁) as (27 square feet, 3 square yards). Plugging x₁ and y₁ into our equation, we get
y/x = k
3 / 27 = k
(3/27) / (3/3) = 1/9* = k
Therefore, the constant of variation is 1/9
Next, as stated previously, y/x = k represents the equation of direct variation. Therefore, y / x = 1/9 as our equation
* because 3 is a factor of both 3 and 27, we can divide both the numerator and denominator by 3 to keep the fraction the same but also simplify it. One way to find the greatest common factor is to list the factors of each number and see the highest number that is a factor of both
The constant of variation is "1/9" and the equation representing the direct variation is y = (1/9)x.
What is the equation?The equation is defined as mathematical statements that have a minimum of two terms containing variables or numbers that are equal.
The equation of direct variation is given by,
y = kx ....(i) where "k" is a constant.
Let y represent the number of square yards and x the number of square feet. Then y varies directly with x.
Given that y varies directly with x, and x = 27, then y = 3.
Substitute the values of y = 3 and x = 27 in the direct variation equation and solve for k:
⇒ 3 = 27k
⇒ k = 3/27
⇒ k = 1/9
Substitute the values of k = 1/9 in the direct variation equation :
⇒ y = (1/9)x
Thus, the constant of variation is "1/9" and the equation representing the direct variation is y = (1/9)x.

Answer:
is your answer how are you
You are taking a survey on the heights of all your classmates. This is an example of categorical data.
True or false
The given statement is false as taking a survey on the heights of all your classmates is an example of quantitative data.
Quantitative data is data that can be measured and expressed as numbers,
such as height, weight, age, etc. Categorical data, on the other hand, consists of distinct categories or groups, such as eye color, gender, favorite color, etc.
Data can be classified into two main types: quantitative data and categorical data.
Quantitative data:
Quantitative data is numerical data that represents measurements or quantities.
It deals with things that can be measured and expressed as numbers.
For example, the heights of people, the weights of objects, the ages of individuals, and the temperatures in degrees are all examples of quantitative data.
Quantitative data can be further divided into two subtypes: discrete and continuous data.
Discrete data: Discrete data consists of whole numbers that cannot be further divided into smaller parts.
For example, the number of students in a class, the number of cars in a parking lot, and the number of books on a shelf are all examples of discrete data.
Continuous data: Continuous data consists of real numbers that can take on any value within a specific range.
For example, the height of a person can be measured as 165.5 cm, 170.2 cm, 178.9 cm, etc. These are all examples of continuous data.
Categorical data:
Categorical data, also known as qualitative data, involves the grouping of items into categories or classes.
It represents characteristics or attributes and is not numerical in nature. Categorical data is further divided into two subtypes: nominal and ordinal data.
Nominal data: Nominal data consists of categories with no intrinsic order or ranking.
For example, eye color ( blue, brown, green) and types of fruits (e.g., apple, banana, orange) are examples of nominal data.
Ordinal data: Ordinal data consists of categories with a meaningful order or ranking.
However, the differences between the categories are not quantifiable.
For instance, educational levels (elementary, middle, high school) and satisfaction levels (very satisfied, satisfied, neutral, dissatisfied, very dissatisfied) are examples of ordinal data.
The height survey of classmates, the data collected would be numerical values representing the heights of each individual.
Since heights are measured and expressed as numbers, this falls under quantitative data, not categorical data.

Solve the inequality.
|11 – xl < 20
[?] < x < [ ]
Answer:
-9<x<31
Step-by-step explanation:
|11 – xl < 20
There are two solutions, one positive and one negative, remember to flip the inequality for the negative
11-x < 20 and 11 -x > -20
Subtract 11 from each side
11-x-11 <20-11 and 11-x-11 >-20-11
-x <9 and -x > -31
Multiply each side by -1, remembering to flip the inequality
x>-9 and x< 31
-9<x<31

Step-by-step explanation:
You are in the third quadrant. You want the answer to come out to the equivalent of 225o or pi + pi/ 4 = 5/4 * pi
x - pi/2 = 5/4 pi
x = 5/4 pi + pi/2

If it takes a team of three painters to paint a 7-room house in a day, how many painters are required to paint a 14-room house in a day?
Answer: 6 Painters
Step-by-step explanation:
Total painters needed to paint 7-room house = 3 painters
Rooms painted by each painter = 3/7
Total painters needed to paint 14-room house = 3/7×14
= 42/7
= 6 painters
Therefore it will require 6 painters to paint 14-room house

Elanor wants to estimate the number of frogs in a reservoir.
She catches 90 frogs from the reservoir and marks them with a non-harmful dye.
Elanor then returns the frogs to the reservoir.
The next day she catches another 70 frogs and 10 of these are marked with the dye.
Work out an estimate for the total number of frogs in the reservoir.
Answer:
approximately 150 frogs
Step-by-step explanation:
To find your estimate, you have to add 90 + 60 because from the 70 that Elanor caught the second day, 10 of them were the ones that she had caught the day before so you have to do 70 - 10 = 60. Therefore, 90 + 60 = 150 estimated frogs.
3) Sabina has a box containing bottles of juice. The three flavorsare
orange, mango and apple. The ratio of these flavor’sis 3 : 5 : 4 There are 35
bottles of mango juice. How many bottles are there altogether?
A )12 B) 28 C) 49 D) 84
Answer:
D
Step-by-step explanation:
sum the parts of the ratio, 3 + 5 + 4 = 12 parts
Mango has 5 parts and there are 35 bottles of mango , so
35 ÷ 5 = 7 ← value of 1 part of the ratio
In total there are 12 parts, then
total bottles = 12 × 7 = 84 → D

Answer:
98 degrees
Step-by-step explanation:
The angles of a quadrilateral add up to 360 degrees, therefore:
(25x+1)+(25x-2)+(20x-1)+82=360
70x +80=360
70x=280
x=4
the angle at C:
25*4-2 = 98 degrees
