The cost of fixing a fault for a software product identified during the implementation phase is approximated at $32,000 USD. How
nydimaria [60]

Answer:

Cost of fixing the software = $ 32,000 USD

Recalling the formula for calculating post design stage = Cost x 3

= 32000 x 3 = 96,000

Now the cost would be:  

Cost = Post Delivery Cost x (Relative Design Cost/Relative Post Delivery Cost)

= 96000 x (32000/96000)

= 96000 x 0.3333

= $36,000 USD

1. Round off 2553 N to three significant figures.
Marizza181 [45]

Answer:

(1) 2553 N = 2550 N

(2) 58342 m = 58300 m

(3) 68.534 s = 68.5 s

Explanation:

To round off a number to any significant number start from the last digit, round it off to 1 if the number is up to 5 and to 0 if the last digit is less than 5. Add this 1 or 0 to the preceding digit and continue the process until you are left with three non zero digits, if you are rounding off to three significant figures.

(1) Round off 2553 N to three significant figures.

= 2550 N

(2) Round off 58342 m to three significant figures.

= 58300 m

(3) Round off 68.534 s to three significant figures.

= 68.500 s (zero after decimal point is insignificant)

= 68.5 s
