Triangle a″b″c″ is formed by a reflection over x = −3 and dilation by a scale factor of 3 from the origin. which equation shows the correct relationship between δabc and δa″b″c′?
coordinate plane with triangle abc at a negative 3 comma 3, b 1 comma negative 3, and c negative 3 comma negative 3
segment b double prime c double prime over segment bc = segment ab over segment a double prime b double prime
segment ab over segment a double prime b double prime = segment bc over segment b double prime c double prime
segment bc = three segment a double prime b double prime
segment a double prime b double prime = three segment bc

People end up tossing 12% of what they buy at the grocery store. assume this is the true population proportion and that you plan to take a sample survey of 540 grocery shoppers to further investigate their behavior. a. calculate the mean and the standard error for the sample proportion p. b. describe the sampling distribution of p in part a. draw a graph of this probability distribution with its mean and standard deviation. what is the probability that your survey will provide a sample proportion more than 15%? c. d. population proportion? what is the probability that your survey will provide a sample proportion within + 0.03 of the
