Tracy flipped a coin 30 times and recorded the frequency of each result in this table. According to the table, what is the experimental probability in simplest form of the coin landing on heads? A. 1/30
B. 2/5
C. 1/2
D. 3/5

C. because you add 1/2 to 1/2 you get 2/4 and then simplifying that would get you 1/2

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 )
