Asurvey of 2000 doctors showed that an average of 3 out of 5 doctors is brand x aspirin. how many doctors use brand x aspirin

since, average of  doctors using brand x aspirin  is 3 out of 5

if we consider one part then one part will be equal to 3/5

total survey consists of 2000 doctors then to find the brand x aspirin we can use the unitary method that is  multiply the total number by one part

2000 x 3/5= 400 x 3

= 1200

so, total 1200 doctors are using brand x aspirin

the required function is .

step-by-step explanation:

from the given table it is noticed that the graph passing through (-3,7), (0,4), (3,1) and (8,-4).

it is a linear function because the value of y is decrease by one as the value of x increase by 1.

the slope of the function is

the slope of the function is -1 and the y-intercept is 4.

the slope intercept form is

where, m is slope and b is y-intercept.

therefore the required function is . the graph of this function is shown below.
