The correct statement about a trend line is: A trend line and a regression line are equivalent terms.
A trend line and a regression line are NOT equivalent terms. They refer to different concepts in data analysis.
1. Trend Line:
A trend line, also known as a line of best fit, is used to represent the general direction or pattern of a dataset. It is a straight line that fits through the data points in a scatter plot to show the overall trend in the data. The primary purpose of a trend line is to identify the underlying pattern or tendency of the data points. Trend lines can be linear or nonlinear, depending on the nature of the data.
In simple terms, a trend line helps us visualize whether the data is increasing, decreasing, or following a specific pattern over time or across a range of values.
2. Regression Line:
A regression line is a specific type of trend line used in linear regression analysis. Linear regression is a statistical method that examines the relationship between two or more variables to predict an outcome. It finds the "best-fit" straight line that minimizes the sum of the squared differences between the actual data points and the predicted values.
The regression line represents the relationship between the independent variable(s) (usually denoted as 'X') and the dependent variable (usually denoted as 'Y'). It provides an equation of the form Y = a + bX, where 'a' is the y-intercept and 'b' is the slope of the line. The regression line serves as a predictive model to estimate the value of the dependent variable based on the values of the independent variable(s).
- A trend line represents the general direction or pattern of a dataset.
- A regression line is a specific type of trend line used in linear regression to predict outcomes based on the relationship between variables.
Therefore, the correct statement is: A trend line and a regression line are NOT equivalent terms.

Jordyn is weighing ingredients on a kitchen scale. The bowls weighs 1 1 2pounds. He adds several scoops of flour. The total weigh of the bowl and flour is 3 pounds. Each cup of flour weighs 1 4pounds. Solve the equation 1 1 2+ 1 4c = 3 to see how many cups of flour he adds.
Answers
Answer:
6cups
Step-by-step explanation:
Given the equation
1 1/2 + 1/4c=3
We are to find the value of c
3/2 + c/4 = 3
c/4 = 3 - 3/2
c/4 = (6-3)/2
c/4 =3/2
Cross multiply
2c = 3×4
2c = 12
c =6
Hence he adds 6cups of flour
20 out of 800 products were found to be defective. At the same rate, how many defective parts will be found in 40,000 products? There would be Blank 1 defective parts out of 40000.
Answers
Answer: 1,000 products
Step-by-step explanation:
If 20 out of 800 products are found to be defective, the percentage of defective products would be:
= 20 / 800
= 2.5%
At this same rate of 2.5%, if there are 40,000 products instead of 800, the number of defective products would be:
= 2.5% * 40,000
= 1,000 products
The standard form of the equation of a parabola is x = y2 + 6y + 1. What is the vertex form of the equation? O A. x = (y + 3)2 - 8 O B. x = (y + 6)2-11 O C. x = (y + 6)2-35 O D. x = (y + 3)2-5
Answers
Answer:
A
Step-by-step explanation:
Given
x = y² + 6y + 1
To complete the square
add/subtract ( half the coefficient of the y- term )² to y² + 6y
x = y² + 2(3)y + 9 - 9 + 1
= (y + 3)² - 8
The vertex form of the equation of a parabola is,
⇒ x = (y + 3)² - 8
What is an expression?Mathematical expression is defined as the collection of the numbers variables and functions by using operations like addition, subtraction, multiplication, and division.
Given that;
The standard form of the equation of a parabola is,
⇒ x = y² + 6y + 1.
Now, We can simplify as;
⇒ x = y² + 6y + 1
⇒ x = y² + 6y + 9 - 9 + 1
⇒ x = (y + 3)² - 8
Thus, The vertex form of the equation of a parabola is,
⇒ x = (y + 3)² - 8

George is reading a book.On Monday he read 1/3 of the book. On Tuesday he reads three-tenths of the remaining pages. He has 35 pages left to read. How many pages are in the book
Answers
Answer:
Step-by-step explanation:
m=p/3
t=(3/10)(1-1/3)
t=(3/10)(2/3)=p/5
p-p/3-p/5=35
(15p-5p-3p)/15=35
7p/15=35
7p=525
p=75

A=15in²
Now we will multiply the area by 4 or the number of other shapes besides the base.

The list below shows the tips earned by Cody while working at Olive Garden. $20, $45, $30.50, $46, $50 What is the mean of the tips earned by Cody?
Answers
Answer:
$38.30
Step-by-step explanation:
Mean is a measure of central tendency. It is the average of a set of numbers. It is determined by adding the numbers together and dividing it by the total number
Mean = sum of the numbers / total number
Sum of the numbers = $20 + $45 + $30.50 + $46 + $50 = $191.50
Total number = 5
Mean = $191.50 / 5 = $38.30
