A general question about Riemann sums... Generally, if a function is increasing, the left Riemann sum is an underestimation and the right Riemann sum is an overestimation. If a function is decreasing, the left Riemann sum is an overestimation and the right Riemann sum is an underestimation. Does this also apply to functions that are entirely negative? Thanks!

The sat and act tests use very different grading scales. the sat math scores follow a normal distribution with mean 518 and standard deviation of 118. the act math scores follow a normal distribution with mean 20.7 and standard deviation of 5. suppose regan scores a 754 on the math portion of the sat. how much would her sister veronica need to score on the math portion of the act to meet or beat regan's score?
