Answer:
b. There's no statistically significant linear relationship between the number of miles driven and the maintenance cost
Step-by-step explanation:
The p-value for the slope estimate show us how strong is the certainty that there are a linear relationship between both variables. In this case, the p-value for the slopes shows if there is a significant relationship between the number of miles driven and the maintenance cost.
If we have a high p-value like 0.7 we can said that there is no certainty in the linear relationship. it means that there's no statistically significant linear relationship between the number of miles driven and the maintenance cost.
Answer:
The slope-intercept form is 
Step-by-step explanation:
To find the slope, use
Replace the x and y values with the points.
Solve.
After that, find the y-intercept form.
Put the equation in point-slope form.
Replace x with 0.
Add 5 to both sides.
Convert to improper fraction form.
The y-intercept is 
Now finally, write in slope-intercept form. (y=mx+b)
m is slope, b is the y-intercept.
Matrices always go row x column.
Count the rows: 4
Count the columns: 3
The matrix is a 4 x 3 matrix
The expression cos240 degrees is equivalent to cos120 degrees
