b.
Answer to Problem 10P
Explanation of Solution
Calculation:
Consider the data given in table.
With the help of graphing calculator regression line is computed,
Now graph of regression line is,
c.
Plot the data and the regression line on the same axes.
c.
Answer to Problem 10P
Explanation of Solution
Calculation:
With the help of graphing calculator regression line is computed,
Now graph both functions on same axis,
d.
Verify the regression line predict as the winning pole vault height for the
d.
Answer to Problem 10P
Prediction model gives higher value than actual height.
Explanation of Solution
Calculation:
Put
The actual height was
Hence, prediction model gives higher value than actual height.

- Determine whether the lines L₁ (t) = (-2,3, −1)t + (0,2,-3) and L2 p(s) = (2, −3, 1)s + (-10, 17, -8) intersect. If they do, find the point of intersection.arrow_forwardConvert the line given by the parametric equations y(t) Enter the symmetric equations in alphabetic order. (x(t) = -4+6t = 3-t (z(t) = 5-7t to symmetric equations.arrow_forwardFind the point at which the line (t) = (4, -5,-4)+t(-2, -1,5) intersects the xy plane.arrow_forward
- Find the distance from the point (-9, -3, 0) to the line ä(t) = (−4, 1, −1)t + (0, 1, −3) .arrow_forward1 Find a vector parallel to the line defined by the parametric equations (x(t) = -2t y(t) == 1- 9t z(t) = -1-t Additionally, find a point on the line.arrow_forwardFind the (perpendicular) distance from the line given by the parametric equations (x(t) = 5+9t y(t) = 7t = 2-9t z(t) to the point (-1, 1, −3).arrow_forward
- Let ä(t) = (3,-2,-5)t + (7,−1, 2) and (u) = (5,0, 3)u + (−3,−9,3). Find the acute angle (in degrees) between the lines:arrow_forwardA tank initially contains 50 gal of pure water. Brine containing 3 lb of salt per gallon enters the tank at 2 gal/min, and the (perfectly mixed) solution leaves the tank at 3 gal/min. Thus, the tank is empty after exactly 50 min. (a) Find the amount of salt in the tank after t minutes. (b) What is the maximum amount of salt ever in the tank?arrow_forwardpleasd dont use chat gptarrow_forward
