In the 1980's it was generally believed around 5% of all children in the U. S. were affected by congenital abnormalities. Some people believe that the increase in chemicals in the environment has led to an increase in the proportion of children in the U. S. with congenital abnormalities. A recent study examined 384 randomly selected children in the U. S. and found that 23 had congenital abnormalities. Is this enough evidence to state the proportion of all children in the U. S. with congenital abnormalities is more than 0.05

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 )
