Initial assessment
An antibody test for a virus has a false positive rate of 598 (if you haven't had the virus it
will say you did 5% of the time) and a false negative rate of 0% (it will always correctly
identify if you had the virus). 1% of the population has had the virus If you tested
positive, what is the probability you had the virus? State answer to 3 significant digits

38.6°

step-by-step explanation:

resultant is 10 pound

smaller force = 8 pound

angle formed = tan⁻¹(

                        =tan⁻¹(

                          =tan⁻¹(0.8)

                        =38.6°

yes, whats the problem?

josh is incorrect

x= 7 and x= -1

step 2 is wrong and honestly first step is not needed, you just need to figure out the factors

i know its wrong because if you plug in the solutions josh found, they do not work (in the original equation)

x^2 -6x -7 = 0

(x-7) (x+1) = 0

x-7=0 x+1=0

x= 7 x= -1
