Answer:
Option E
Step-by-step explanation:
This survey will not be reliable as it is chosen for convenience; the first 120 students to arrive in school on a particular morning and this collection of individuals may not be a representative of the population. The study may become biased because it does not take into account the latecomers among the students which might have been changed the study from systematically favoring certain outcomes.
If the answer can be left in a fraction than this is the solution: 2×5/8=5/4
5/4-1/3=11/12
if you mean the answer must be left in a whole number than.. I don't really know how to do it
X=6 and y=-9. Not sure if y is correct since I kind of rushed but I hope this helps!
(x-center)^2+(y-center)^2=r^2
x^2+y^2=r^2
(5)^2+(-12)^2=r^2
25+144=r^2
169=r^2
r=13
Related to ur last question......food totaled 17.42
17.42 - 1.75 = 15.67...this is with the coupon added
15.67 + 0.87 = 16.54....this is the final total....with tax included
so ur answer is 16.54
