Many people in the U. S. think that the penny should be eliminated from economy, but 67% of people think that it still should be minted. If a sample of 15 people were randomly selected, how many of the 15 are expected to say that they want the U. S. to continue making the penny?

Step-by-step explanation:

It's true that it costs more to mint these two coins than they are worth. In 2017, it cost the U.S. Mint 1.8 cents to make each penny and 6.6 cents for each nickel. ... For every dollar's worth of coins it shipped out, the Mint made 45 cents.

there are lots of ways.   pick's theorem tells us if the vertices are lattice points the area a is

a = b/2 + i - 1

where b is the number of boundary lattice points and i is the number of interior lattice points.

in the figure i count b=16, i=50 so

a = 8 + 50 - 1 = 57

let's try the shoelace formula.   the area is half the sum of the cross products of the sides.  

a(-2,6)   -2(2)-6(-5) = 26

b(-5,2)   -5(-3) - 2(-2) = 19

c(-2,-3) -2(-3) - (-3)(4) = 18

d(4,-3)   4(3) - (-3)(5) = 27

e(5,3)   5(3) - 3(1) = 12

f(1,3)     1(6) - 3(-2) = 12

a(-2,6)

each of the cross products is twice the area of the triangle with the associated side and one vertex the origin. so the area of abo=26/2=13.

area = (1/2) (26 + 19 +   18 + 27 + 12 + 12) = 57

that checks!
