This one actually made me think. I like your teacher.
2h 30min (2.5)×30mph=75m
1h 30min (1.5)x50mph=75m
1 hour longer when driving to Arkansas
______________________________
11h 12min (11.2)×300mph=3360m
4h 48min (4.8)×700mph=3360m
11h 12min from NY to Paris.
300. When the number is 5 and up, then you round up to the next digit. For example, 350 would round up to 400. But seeing as it is 346, you round down.
Answer:
56 hours
Step-by-step explanation:
we know that
A relationship between two variables, x, and y, represent a proportional variation if it can be expressed in the form 
or 
Let
x -----> the number of hours
y ----> the amount earned in dollars
This problem represent a proportional relationship between the variable x and the variable y
Find the value of the constant of proportionality k
For (3,27) ----> 
For (9,81) ----> 
For (21,189) ----> 
The constant of proportionality k is 9
The linear equation is
For y=$500
substitute in the equation and solve for x
Divide by 9 both sides

Explained below.
Step-by-step explanation:
Consider the variables height and weight.
It is usually seen that taller people are heavier than shorter people.
So a regression analysis can be used to specify this belief.
The statistical questions that are being asked here are:
- What the independent and dependent variables?
- Are there any other factor influencing the dependent variable other than the independent variable?
The variable <em>Y</em> is considered as the dependent variable and the variable <em>Y</em> is considered as the independent variable. And the main purpose of the regression analysis is to predict the value of <em>Y</em> when the value of <em>X</em> is given.
The linear regression model can be used to predict the past and future value of the dependent variables provided that the independent variables for those times are provided.
