You measure 45 backpacks' weights, and find they have a mean weight of 64 ounces. Assume the population standard deviation is 3.1 ounces. Based on this, what is the maximal margin error associated
with a 95% confidence interval for the true population mean backpack weight.
Give your answer as a decimal, to two places
x ounces

Solve the equation using the given values: x= -2.5; y= -7.51. 2xy + 2x²

Hurry and answer this! circle x with a radius of 6 units and circle y with a radius of 2 units are shown which steps would prove the circles similar? translate the circles so they share a common center point, and dilate circle y by a scale factor of 4. translate the circles so the center of one circle rests on the edge of the other circle, and dilate circle y by a scale factor of 4. translate the circles so they share a common center point, and dilate circle y by a scale factor of 3. translate the circles so the center of one circle rests on the edge of the other circle, and dilate circle y by a scale factor of 3

Type the correct answer in the box. use numerals instead of words. if necessary, use / for the fraction bar.
