Given:
62% of the residents visit Comet Mall.
73% of the residents visit Star Mall.
48% of the residents visit both malls.
To find:
The probability that a resident chosen at random shops at either Comet Mall or at Star Mall.
Solution:
Let A be the event that the residents visit Comet Mall and B be the event that residents visit Star Mall. Then, we have
We need to find the probability that a resident chosen at random shops at either Comet Mall or at Star Mall. It means, we have to find the value of 
.
We know that,
On substituting the given values, we get
Therefore, the probability that a resident chosen at random shops at either Comet Mall or at Star Mall is 87%.
Answer:
Mercator projection

There are other types of projections, correcting some issues, but with their own flaws too. The only accurate representation of the planet is a globe, since it matches the shape of the planet.
Answer:
AB = 5.8 units
Explanation:
The distance of line segment AB shown in the attachment below can be calculated using the distance formula, 
, assuming that each box in the graph equals 1 unit.
A(2, 4)
B(-3, 1)
Let,
Plug in the values into the distance formula
(nearest tenth)
AB = 5.8 units
