Applicants for temporary office work at carter temporary agency who have successfully completed an administrative assistant course are then placed in suitable positions by nancy dwyer and darla newberg. employers who hire temporary through the agency return a card indicating satisfaction or dissatisfaction with the work performance of those hired. from past experience it is known that 80% of the employees placed by nancy are rated as satisfactory, and 65% of those placed by darla are rated as satisfactory. darla places 55% of the temporary office at the agency, and nancy places the remaining 45%. if a carter office worker is rated unsatisfactory, what is the probability that he or she was placed by darla? (round your answer to three decimal places.)

0.681

Step-by-step explanation:

Let's define the following events:

S: a Carter office worker is rated satisfactory

U : a Carter office worker is rated unsatisfactory

ND: a Carter office worker is placed by Nancy Dwyer

DN: a Carter office worker is placed by Darla Newberg

We have from the original text that

P(S | ND) = 0.8, this implies that P(U | ND) = 0.2.

P(S | DN) = 0.65, this implies that P(U | DN) = 0.35. Besides

P(DN) =  0.55 and P(ND) = 0.45, then we are looking for

P(DN | U), using the Bayes' formula we have

P(DN | U) = = =0.681

the correct option is:

b. a value of the variable that makes the polynomial equal to zero.

the root or roots of a polynomial are the values of the variable that makes the polynomial equal to 0. we can find the roots of a polynomial making the expression equal to 0 and then, isolating the variable (it it has just one variable).

for example, given the following polynomial:

the root or zero of the polynomial, can be found by making the expression equal to 0, and then, isolating the variable, so, finding the root we have:

therefore, we have that the root of the polynomial is equal to 2.

we must remember that the number of roots that a polynomial can have, will depend on the degree of the polynomial, a first degree polynomial have will have one single root, a second degree polynomial (quadratic expression) may have two roots and so.

hence the correct option is:

b. a value of the variable that makes the polynomial equal to zero.

have a nice day!
