Use the formula to find the standard error of the distribution of differences in sample means, x₁-x₂. Samples of size 105 from Population 1 with mean 81 and standard deviation 10 and samples of size 85 from Population 2 with mean 72 and standard deviation 18

(Round your answer for the standard error to two decimal places).

standard error =

No i refuse to tell you the answer but the estimate is 10

Answercounterclockwise rotation about the origin by 180 degrees followed by reflection about the y-axisexplanationthe given figure has verticesrecall that for counterclockwise rotation about the origin, when we rotate figure pqrs counterclockwise through an angle of 180° about the origin, the coordinates will becomenext, we reflect in the y-axis by negating the x-coordinates of the resulting figure to obtain,therefore the correct answer is c
