Sam is making wheels for tricycle. He can make 400 wheels in 2 hours. how many hours will it take him to make 1,000 wheels.

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

So the book has 75 pages.

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.

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

Answer:

60in²

Step-by-step explanation:

Since lateral surface area means all the shapes except the base, we will ignore the square in the middle.

A=1/2(b*h)

A=1/2(10*3)

A=15in²

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

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
