A project can be completed by 8 workers in 30 days. In order to complete the project sooner, the company plans to hire additional workers. How many total workers are needed to complete the project in 16 days?

15

Step-by-step explanation:

Given

8 Workers can a work in 30 days

i.e. 1 workers can do the same job in

If additional workers is hired to do the same work in 16 days

suppose Now x no of workers do the job so, one worker will do the same job in

No of days require to complete the job by one worker  remains the same (considering all are equally efficient)

So a total of 15 workers is required to do the same job in 16 days

answer: 33 ( approx)

step-by-step explanation:

since, in the linear regression formula, the slope is the a in the equation y = b + ax ( by comparing it with the general equation of line y = mx + c )

where,

here given table is,

price ($), x   :           18         23       25       29       30       33

pairs sold, y :         16         13         10       8         6       2

so, ,   ,   ,

and   ,

thus, slop of the given line is,

⇒  

⇒   ≈ 33
