mean=31
st.dev.=0.8
x=32

Step-by-step explanation:
I honestly don't know how I got my answer but I know it's correct
A proportional graph includes a line that is A) straight and B) passes through the origin/(0,0).
graphs A and D would be incorrect since they do not include straight lines. graphs B and C would be incorrect since they do not include lines that intersect the origin.
the only correct answer here is graph E since it’s both straight and passes through (0,0). hope this helps!
