In one study on rideshare distances, the median rideshare distance was 175 miles. A histogram of the data set was skewed to the left.Which of the following values for the mean rideshare distance is most plausible? 21.2 miles 23.5 miles 5.7 miles The most plausible value for the mean is $\square $ because when the data set is skewed to the left, the mean is $\square $

Factor using the sum or difference of cubes.(Check by multiplying.) $y^{3}+64$ Part 1 of 2 Factor using the sum or difference of cubes. $y^{3}+64=(y+4)(y^{2}-4y+16)$ Part: $1/2$ Part 2 of 2 Check: $(y+4)(y^{2}-4y+16)=y^{3}-\square y^{2}+\square y+\square y^{2}-16y+64=y^{3}+64$
