What is the equation of this circle in standard form? (x+1)2+(y+2)2=49 (x−1)2+(y−2)2=7 (x−1)2+(y−2)2=49 (x+1)2+(y+2)2=7 A circle on a coordinate plane centered at begin ordered pair negative 1 comma negative 2 end ordered pair. The horizontal x-axis ranges from negative 10 to 10 increments of 1. The vertical y-axis ranges from negative 10 to 10 in increments of 1. The circle passes through begin ordered pair negative 6 comma negative 2 end ordered pair, begin ordered pair negative 1 comma 5 end ordered pair, begin ordered pair 6 comma negative 2 end ordered pair, and begin ordered pair negative 1 comma negative 9 end ordered pair.

If your score on your next statistics test is converted to a z score, which of these z scores would you prefer: minus2.00, minus1.00, 0, 1.00, 2.00? why? a. the z score of 2.00 is most preferable because it is 2.00 standard deviations above the mean and would correspond to the highest of the five different possible test scores. b. the z score of 0 is most preferable because it corresponds to a test score equal to the mean. c. the z score of minus2.00 is most preferable because it is 2.00 standard deviations below the mean and would correspond to the highest of the five different possible test scores. d. the z score of minus1.00 is most preferable because it is 1.00 standard deviation below the mean and would correspond to an above average
