A national forest service wanted to estimate the number of deer in a particular national park. They caught and tagged 55 deer and released them back into the park. Later they selected a sample of 319 deer. Of the
319 deer, 29 were tagged. Assuming that the proportion of tagged deer in the sample holds for all deer in
the forest, what is the best estimate of the number of deer in the park?

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 )
