Answer:
a) 0.58
b) 0.0464
Step-by-step explanation:
A= The person is sick
B= The give a positive result
P(A)=0.03
P(A')=1-P(A)=1-0.03=0.97
P(B|A)=0.9
P(B|A')=0.02
P(B)=P(B|A)P(A)+P(B|A')P(A')=0.9*0.03+0.02*0.97=0.0464
t(1) = 1 = 2(1)-9 / 1 - a
1 - a = 2 - 9 = -7
a = 1 + 7
a = 8 answer
If you would like to find the value of a in the polynomial, you can do this using the following steps:
(y - 4)(y^2 + 4y + 16) = y^3 + 4y^2 + 16y - 4y^2 - 16y - 64 = y^3 + 4y^2 + ay - 4y^2 - ay - 64
a = 16
The correct result would be 16.
