Answer:
b. 40m+0.25=25m+0.45
Step-by-step explanation:
Step one:
given data
First Rate Rental
Charges $40 a day plus $0.25 per mile.
let the number of days be m
and the total charges be y
y= 40+0.25m---------------------1
Star Rental
charges $25 a day plus $0.45 per mile.
y= 25+0.45m-----------------------2
Step two:
equate 1 and 2 above we have
40+0.25m= 25+0.45m

Answer: E. Parametric estimating
Step-by-step explanation:
A parametric estimate is the estimating process that uses a statistical relationship between past project's data and other variables to give an estimation for the parameters such as duration ,cost and budget.
It is based on parameters that summarize the risk , costs of algorithm , project , process , complexity and service.
It can create a greater level of accuracy.
Therefore , Parametric estimating is an estimating technique that uses a statistical relationship between historical data and other variables to calculate an estimate for activity parameters such as duration and cost.
Hence , the correct answer is E. Parametric estimating.
