Oliver is determining the number of males in his math class. oliver is collecting what kind of data? a) bivariate b) categorical c) qualitative d) univariate

When Oliver is considering the number of males, he typically assigns people to two categories: make or female, which makes the variable bi-variate : with two values.("bi" means "two).

If he's more inclusive, and adds the category of "other", it would be a categorical data - with 3 categories.

In the first triangle 80+20+p=180 (since sum of all angles of a triangle is 180)so p= 80also in second triangle 55+45+q=180 (since sum of all angles of a triangle is 180)so q=80so we can conclude that p=80 degrees q=80 degrees so p=q=80 degreeshence option b is correct
