Determine whether the quantitative variable is discrete or continuous. number of interceptions made by a defensive back is the variable discrete or continuous? a. the variable is continuous because it is not countable. b. the variable is continuous because it is countable. c. the variable is discrete because it is countable. d. the variable is discrete because it is not countable.

The number of interceptions made by a defensive back is definitely countable because it is finite and also it is not continuous because each interception is different and is unique. That is to say, one interruption happens and then then next. They do not happen in a continuous manner.

Thus, the number of interceptions made by a defensive back are countable and are discrete. Having a look at the options we can see that Option C matches as it says "the variable is discrete because it is countable".

Thus Option C is the answer.

check the picture below.

well, the angle at the vertex d is clearly not a right-angle, let's check for the one at the vertex f which does look like,   however if it's indeed, that means ef is perpendicular to df, in which case their slopes will be negative reciprocal of each other.

so the negative reciprocal of the slope of ef is 1, however the slope of df is not 1, is 1/2, so nope, they're not perpendicular lines.
