You have a function taking in two integer variables, x and y. You want to subtract x from y, but you want to make sure the result does not overflow. Write some lines of code (assuming x and y are already defined integers with values in them) to check if the result would be an overflow if x was subtracted from y. Do this without allowing an overflow to happen.

For each of the following, state whether you expect the distribution to be symmetric, right skewed,...

For each of the following, state whether you expect the distribution to be symmetric, right skewed, or left skewed. Also specify whether the mean or median would best represent a typical observation in the data, and whether the variability of observations would be best represented using the standard deviation or IQR. Explain your reasoning. -Housing prices in a country where 25% of the houses cost below $350,000, 50% of the houses cost below $450,000, 75% of the houses cost below...

Each of the following scenarios describes a correlation between two variables. State whether the correlation is most likely due to a coincidence, a common underlying cause, or a direct cause. If there is an underlying cause, state what you think it is. If you believe that one variable directly causes the other, suggest possible physical causation. 1. Sales of winter boots are positively correlated with the sale of sidewalk salt. 2. I’ve noticed that the more hours I work each...
