If I can read the #'s correctly:
add the yes answers together 23+147 = 170
add the no answers together 112+48= 160
so your ratio of haves to have nots is 170 to 160
but both sides can be divided by 10, so it can be simplified to 17 to 16.
Good Luck!
-The area of A is 647 beacuase 16*12 is 192 and 13*35 is 455 and 455+192 is 647.The perimeter is A is 120 because 16+25+12+19+35+13 is 120.
-The area of B is 192 because 8*12+8*12 is 192.The perimeter of B is 70 because 8+12+8+7+8+12+8+7 is 70.

Answer:
a) is a function
b) is not a function
Step-by-step explanation:

b) There are vertical lines that intersect the curve more than once: x=3, for example. The graph does not pass the vertical line test, so DOES NOT REPRESENT A FUNCTION.
He only asked students in his university and he stated that it represented the whole nation (his university does not represent the whole country.)
