Answer:
The complete question is as shown in the attached figure 1
The Venn diagram is the attached figure 2
Let: R⇒ribs , H⇒hamburgers and C⇒corn
People would eat all three = 53
People would eat only R and H = 56 - 53 = 3
People would eat only C and H = 54 - 53 = 1
People would eat only R and C = 55 - 53 = 2
People would eat only H = 60 - (53+3+1) = 60 - 57 = 3
People would eat only R = 59 - (53+3+2) = 59 - 58 = 1
People would eat only C = 56 - (53+1+2) = 0
See Vinn diagram.
=========================================================
a. How many people did not want any of these foods?
people did not want any of these foods = 64 - (53+3+1+2+3+1) = 1
b. How many people would eat ribs but not corn?
people would eat ribs but not corn = 1+3 = 4
c. How many people would eat something as long as it was not a hamburger?
people would eat something as long as it was not a hamburger= 1+2 = 3
d. How many people would eat only corn?
people would eat only corn = 0
e. How many people would eat exactly two foods?
people would eat exactly two foods = 1 + 2 + 1

Answer:
Step-by-step explanation:
Assuming this complete problem: "A cell tower is located at (-8, 4) and transmits a circular signal that covers three major cities. The three cities are located on the circle and have the following coordinates: G (-4, 7), H (-13, 4), and I (-8, -1). Find the equation of the circle"
For this case the generla equation for the circle is given by:
From the info we know that the tower is located at (-8, 4) so then h = -8 and k = 4, so then we need to find the radius. So we have the equation like this:
If the 3 points are on the circle then satisfy the equation. We can use the first point (-4,7) and if we replace we can find the value for
So then
And if we replace the second point we got this:
And for the third point we have:
And we got the same result.
So then our final equation is given:
