Which of the following 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? a. bottom-up estimatesb. influence diagramsc. swot analysisd. analogous estimatinge. parametric estimating

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.

fa tha first one you gonna add y to both sides

it look like this

x-y+y=6+y

x=y+6

therefore your answer is

x =y+6

fa tha second one

you gonna flip tha equation

it gonna look like x-4y=y

then add 4 to both sides

it gonna look like tha

x-4 +4 =y +4

so therefore tha answer is x=y+4
