The probability that an electronic device produced by a company does not function properly is equal to 0.1. if 10 devices are bought, then the probability, to the nearest thousandth, that 7 devices function properly is
a. 0.057
b. 0.478
c. 0.001
d. 0

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.

just needed some points but try socratic
