Determine whether the results appear to have statistical? significance, and also determine whether the results appear to have pr
actical significance. In a study of a gender selection method used to increase the likelihood of a baby being born a? girl, 2089 users of the method gave birth to 1027 boys and 1062 girls. There is about aa 23?% chance of getting that many girls if the method had no effect. Because there is a 23% chance of getting that many girls by? chance, the method has A) has statistical significance B) does not have statistical significance C) has practical significance D) does not have practical significance. A) Most or B) Not many couples would likely use a procedure that raises the likelihood of a girl from the approximately? 50% rate expected by chance to the [what %?] produced by this method, so this method A) has statistical significance B) does not have practical significance C) does not have statistical significance. D) has practical significance.
Let the width of the rectangle be x Then length =x-4 Area=x(x-4)=140 x²-4x=140 x²-4x-140=0 x²-14x+10x-140=0 x(x-14)+10(x-14)=0 (x-14)(x+10)=0 Therefore,length=14 cm and width=10 cm
which would be 1 third times 3.14 times 6 squared times 33
Step-by-step explanation:
okay so your dealing with a cone and a hemisphere. so what you would do is the cone equation is multiplied by multiplied by the radius squared times the height so what u would o is plug in the things you know .
