Plz , will give brainliest! type the correct answer in each blank. the line of best fit represents the number of miles jean covered at different speeds during a trip. if the speed is represented by x and the distance covered is represented by y, the equation of the best line of fit is y =(blank) . she covered about (blank) miles at the speed of 50 miles per hour.

Answer: d. 39 cmin the diagram, the approximate length of the minor arc de is 39 centimetres.step-by-step explanation: the formula for the length of an arc in a circle is as displayed below.let the length of the minor arc de = xx = 2( pi )r × angle of sector / 360°from this, we will substitute the values given from the problem into the formula to obtain the length of the minor arc de.x = 2( pi )r × angle of sector / 360°r = radius = 25cmpi as an approximate value = 3.14angle of sector = 120°x = 2( 3.14 )( 25 ) × 120° / 360°x = 157 × 1 / 4x = 39.25x = 39 ( rounded to the nearest whole number as an approximate value )
