You take a random sample of five City College students and record what color shirt they are wearing. Here are the results: Black Black White Blue Red Calculate a point estimate for the population proportion of City College students who wear black shirts on any particular day, based on the data in this sample. 25. Give the symbol used to denote this point estimate. Write your answer on paper and upload a photo or scan, or else put your answer in an electronic file and upload the file.

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 )
