Answer:
There are many solution for this problem
The solutions are -2, -3, -4..... And even fractions like -11/7, -12/7, etc.
Hope this helps!
So I added all of the numbers of tourists together, I got 30 tourists. Then I saw that the number of tourists that visisted the museum but not the zoo was 5. I divided 5 by 30 and got that there was a 16% chance that a randomly selected tourist would of visited the museum but NOT the zoo.
Hope this helps!

Solution :
Let us consider the squares be ![$[1, 16] \times [16, 32]$](https://tex.z-dn.net/?f=%24%5B1%2C%2016%5D%20%5Ctimes%20%5B16%2C%2032%5D%24)
If x ranges from the 0 to 16 and the y ranges from 16 to 32, we see that the boundary of the region
which goes from the 
.
And so it is easier to find the area of region where 
. This is the triangle with points 
as its vertices.
The area if the triangle is = 
= 
Now the entire area is 
= 256
Then, 
or 
Thus the answer is 
Answer:
The center is at ( (-1, -2) and the radius is 5.
Step-by-step explanation:
X^2 + 2X + Y^2 + 4Y = 20
Complete the square on the x and y terms.
(x + 1)^2 -1 + (y + 2)^2 - 4 = 20
(x + 1)^2 + ( y + 2)^2 = 25 Comparing this with the standard form:
(x - h)^2 + (y - k)^2 = r^2
- the center is at ( (-1, -2) and thr radius is 5.
