Answer:You have roughly the same chance of being called as anyone else living in the United States who has a telephone. This chance, however, is only about 1 in 154,000 for a typical Pew Research Center survey. To obtain that rough estimate, we divide the current adult population of the U.S. (about 235 million) by the typical sample size of our polls (usually around 1,500 people). Telephone numbers for Pew Research Center polls are generated through a process that attempts to give every household in the population a known chance of being included. Of course, if you don’t have a telephone at all (about 2% of households), then you have no chance of being included in our telephone surveys.

-8(4+9r) = 7(-2-11r)
-32-72r = -14-77r
5r = 18
r = 3.6
The amount of wrapping paper he use is 62.4 square inches
<h3>How to calculate the surface area of a prism</h3>
The formula for calculating the total surface area is expressed as:
Area = 4(area of triangle)
Find the area of the triangle
A = 0.5(6)(5.2)
A =3(5.2)
A = 15.6 square inches
TSA = 4(15.6)
TSA = 62.4 square inches
Hence the amount of wrapping paper he uses is 62.4 square inches
