You are the foreman of the Bar-S cattle ranch in Colorado. A neighboring ranch has calves for sale, and you are going to buy some calves to add to the Bar-S herd. How much should a healthy calf weigh? Let x be the age of the calf (in weeks), and let y be the weight of the calf (in kilograms).  x 1 5 9 16 26 36  y 37 49 75 100 150 200  given Σx=93 Σy=611 Σx2=2335 Σy2=81895 Σxy =13657 and r =.9985  a) Find x and y. Then find the equation of the least squares line ^                                                 Y=a+bx (round 4 decimals places)  x= y=  ^ y=___+____x  b) Find the value of the coefficient of determination r2. What percentage of the variation in y can be explained by the corresponding variation in x ans the least squares line? What percentage is unexplained?(round your r2 four decimal places. Round your answers for the percentages to two decimal places.)  r2=___ explained=___% unexplained=___% c) the calves you want to buy are 24 weeks old. What does the least squares line predict for a healthy weight?( round your answer two decimal places)  ___ kg

Differential Equations

Have you ever observed the movement of the satellites and rockets or how the planets go around the sun in their orbits? How will you determine their motion? Definitely they follow some scientific laws and these kinds of problems are framed as differential equations.
