The answer is C. 2 hours and 15 minutes. Please refer to the attached document to see the image for better understanding of solution.
Philadelphia = Point A
Pittsburgh = Point B
X = distance traveled by Michelle
(305-X) = distance traveled by Rich
The general formula used is:


Assigning values gives 2 equations:
For Michelle:

For Rich:

Substituting both equations gives:
X = 146.852 miles
t = 2.26 hours or approximately 2 hours and 15 minutes
The inequality that represents this phrase is n+6 > 31.
<span>Well, think of it this way? How many times does 5 go into 9?
5 * 1 = 5
5 * 2 = 10
So 5 goes into 9 one time. Then you have to subtract that 5 from 9 to be left with your fraction value.
1 and 4/5 is your mixed number.</span>
Answer:
A
Step-by-step explanation:
Simple linear regression is a statistical method that summarizes and study relationships between two continuous quantitative variables.
One variable is regarded as the predictor, explanatory, or independent variable and the other variable is regarded as the response, outcome, or dependent variable.
Two variables can be denoted by X and Y.
Among the given options, the correct option is A. After conducting a hypothesis test to test that the slope of the regression equation is nonzero, you can conclude that your predictor variable, X, causes Y
