A box contains twenty-one marbles of the same size. Seven of the marbles are white, four are black, and ten are green. If two of the marbles are randomly selected from the box, what is the probability that the first marble is white and the second is green, given that
the first marble is not replaced before the second marble is selected?

Answers: the graph is translated down 1 unit and the domain and range of g(x) is the same as the domain and range of f(x).

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 )
