What is the probability that this spinner will land on a 3 in one spin? a. 1/8 b. 1/4 c. 1/3 d. 3/8

This questions answer is B since there are two 3 out of 8 its 2/8 then you make them smaller divide each top with 2 the you get 1/4

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.

the first dot plot best represents the data
