Answer:
1.345
Step-by-step explanation:
I think the question you are trying to ask is (15/100) + (1/50) + (1.175) =
Convert all the fractions which includes 15/100 and 1/50 to decimals
Thus we have 15/100 = 0.15 and 1/50 = 0.02
The question is: 0.15 + 0.02 + 1.175 = 1.345
Answer: D. 21ways.
Step-by-step explanation:
This is based on selection, fixing two '3' numbers into 5numbers to make it 7 numbers can be done in 7C2 ways.
Generally, nCr = n!/(n-r)!r!
7C2 = 7!/(7-2)!2!
=7!/5!2!
=7×6×5!/5!×2!
=7×6/2

Compute the gradient of 
.
Set this equal to the zero vector and solve for the critical points.
The last case has no real solution, so we can ignore it.
Now,
so we have two critical points (0, 0) and (2, 2).
Compute the Hessian matrix (i.e. Jacobian of the gradient).
Check the sign of the determinant of the Hessian at each of the critical points.
which indicates a saddle point at (0, 0);
We also have 
, which together indicate a local minimum at (2, 2).
