Since there are 1500 people in your random sample, and the statistics show that 19.9% of people in that bracket smoke, convert your decimal to a percent (divide by 100, so you would get 0.199) and multiply that by the number in your sample, 1500. This gives you 298.5. You cannot have a fraction of a person, so round up to 299 people.

180=interior angle of triangle so
angle TRS IS 180-9X as it is (angles on a straight line)
then angle RTS=5x
and angle TSR=9+x
180=180-9x+5x+9+x
180=-3x+189
180-189=-3x
-9=-3x
x=-9/-3
x=3
Answer:
a rectangle
Step-by-step explanation:
because 2 sides are the same the other 2 arent it has four sides with straight angles
Area is given by the formula
Area = length*width
Filling in the given information, we have
51 = (2m+7)*(m-2)
2m² +3m -65 = 0
(m -5)(2m +13) - 0
m = -13/2 or 5
Since dimensions of physical objects are non-negative, the value of m is 5.
