1. The foowing is an equivalence relation on {g, e, r, m, a, n, y} : {(g, g),(g, m), (g, n), (m, g), (m, m), (m, n), (n, g), (n, m),(n, n), (e, e), (r, r), (r, a),(a, r), (a, a),(y, y)}.
What is the partition that this relation induces?

answer

a,b, and d

explanation

a reflection angle is more than

but less than;

an angle that measures

is a reflex angle.(true)

an angle that measures less than

is acute.(true)

provided we are considering angles greater or equal to zero.

an acute angle lies in the range.

an obtuse angle is less than 180° but more than 90°

an angle that measures 300° is obtuse (false)

an angle that measures 65° is an acute angle.(true)

from the figure we get,

the x axis shows   the months and,

the y-axis shows the number of satisfied customer.

each line or each cell in upward direction (y-axis) shows 500.

the appropriate scale for the y - axis is: -

a = 2000 customers

b = 4000 customers

c = 6000 customers

d = 8000 customers

e = 10000 customers

f = 12000 customers

g = 14000 customers

i hope this is what you were looking for.
