Answer:
10 is 2 / 3% of 1500
Step-by-step explanation:
Answer:
the change in C can be calculated by evaluating the cost function at Q = 356 and Q = 357
change in C = 1,020,000/357 + 7.6*357 - 1,020,000/356 + 7.6*356 ≈ -0.43
Instantaneous rate of change in C is first order derivative C':
C'(Q) = -1,020,000/(Q^2) + 7.6
C'(356) = -1,020,000/(356^2) + 7.6 ≈ - 0.45
Hope my answer helps.
Answer:
x = 57/28
y = -95/84
z = 97/168
Step-by-step explanation:
Use the application in the next link: https://www.zweigmedia.com/RealWorld/tutorialsf1/scriptpivotold.html
Start with the expanded array:
then using the tool provided, make row operations until you find the solution:
r2 = r2-3r1
r3 = r3+2r1
r2 = r2*(-1/13)
r1 = r1- r2*5
r3 = r3+ r2*-3
r3 = r3*13/168
r2 = r2- r3*22/13
r2 = r2+ r3*6/13
Here you have a reduced array an therefore the answers to each variable are on each row:
Total points scored=72(2)+9
=153
Mean=153/7
=21 6/7
=21.9 (3s.f.)
