Hey there!
The answer is C. teenagers across the country.
A population is the whole. It's every member of the group, which is pretty much the opposite of a sample. A sample is just a fraction or a percentage of the group.
The sample is the homeroom class, who is the group being surveyed. But the population the survey is determining data for overall is teenagers across the country.
We also know that they are across the country because we are told that the gym is a national franchise.
Hope this helps!

ANSWER
the area of the trim around the glass in the window is option ( D)
i.e (x²+7x+3)
REASON
As given in the question
A window frame has a length of (5x+3) inches an a width of (x+6) inches.
As the shape of the window in the form of rectangle.
Formula
Area of the rectangle = length × breadth
put the value in the above equation
we get
Area of window = (5x+3)× ( x + 6)
= 5x² + 33x + 18 inches²
As given in the question
The area of the glass in the window is (4x²+26x+15) square inches.
Area trim around the glass in the window = area of the window - area of the glass.
put the value
we get
= ( 5x² + 33x + 18 ) - ( 4x²+26x+15)
= 1x²+ 7x + 3 inches²
therefore the correct option is (D)
Hence proved
Answer:
15
Step-by-step explanation:
1/5x = 2/5
x = 2/5 * 5/1 (5/1 is the inverse of 1/5)
x = 2
