Dominique and Ella are comparing
whose jet traveled faster. The graph
shows the relationship between the
total distance Dominique traveled
and the time in hours. The distance Time (1)
Who, if anyone, traveled at a faster
speed? Explain. i hope this helps you.
Answer:


And the slope would be:

Now we can find the means for x and y like this:


And we can find the intercept using this:

So the line would be given by:

And the best option is:
A. y = 0.894x + 0.535
Step-by-step explanation:
We have the following dataset given
x: 5,6,9,10,14
y: 4,6,9,11,12
We want to find the least-squares line appropriate for this data given by this general expresion:

Where m is the slope and b the intercept
For this case we need to calculate the slope with the following formula:

Where:


So we can find the sums like this:





With these we can find the sums:


And the slope would be:

Nowe we can find the means for x and y like this:


And we can find the intercept using this:

So the line would be given by:

And the best option is:
A. y = 0.894x + 0.535
Answer:
412.5 miles
Step-by-step explanation:
1) 2.75/0.5=5.5
2)5.5x75=412.5
