Mean: 74
(72+72+73+75+78) divided by 5
median: 73
(line all the numbers up in numerical order then cross out one from each side and repeat process until in the middle)
Answer:
I think it is C
Step-by-step explanation:
Reason being because the question said at least 15 points more so it can't
be 12 equal to 12 points. so you could eliminate the greater than or equal to.
so that leaves c and d. can't see how it is D because if he has 15 points more can't see why his other portion of points could take away 15 so that leaves C.
hope that helps
2.1428 is the answer not in fraction
Implicit differentiation
take derivitive of both sides
1=15y^2dy/dx-12ydy/dx
1=dy/dx(15y^2-12y)
divide both sides by (15y^2-12y)
1/(15y^2-12y)=dy/dx
sub the point (-4,1)
1/(15(1)^2-12(1))=dy/dx
1/(15-12)=dy/dx
1/3=dy/dx
slope is 1/3
3^3*5^2*13 is the prime factorization of 8775
