Answer:
3
Step-by-step explanation:
Because 30 divided by 5 =6 which is the miles so divide 15 by 5 and the minutes are 6 so 6x5 so 3
Answer <u>(assuming it can be in slope-intercept form)</u>:
Step-by-step explanation:
1) First, find the slope of the line between the two points by using the slope formula, 
. Substitute the x and y values of the given points into the formula and solve:
Thus, the slope of the line is 
.
2) Next, use the point-slope formula 
to write the equation of the line in point-slope form. Substitute values for 
, 
, and 
in the formula.
Since represents the slope, substitute in its place. Since and represent the x and y values of one point the line intersects, choose any of the given points (it doesn't matter which one, it will equal the same thing) and substitute its x and y values into the formula as well. (I chose (-2,0), as seen below.) Then, isolate y and expand the right side in the resulting equation to find the equation of the line in slope-intercept form:
The confidence interval extremities are given by the formula:
m +/- (z · σ / √n)
In your problem:
m = 3.13
<span> σ = 0.23
n = 36
The z-score for a 99% confidence interval is 2.576
Therefore:
</span>m - (z · σ / √n) = 3.13 - (2.576 · 0.23 / √36) = 3.031
<span>m + (z · σ / √n) = 3.13 + (2.576 · 0.23 / √36) = 3.229
Therefore, the confidence interval is (</span>3.031, <span>3.229).</span>
