Answer:
0.981
Step-by-step explanation:
We have to find the probability that an individual who has the symptoms and who reacts positively to the test has hepatitis
Let 
be the event that denotes the symptoms has hepatitis and 
denotes the symptoms have not hepatitis
Let A be the event the denotes the blood test result positive
We have to find the value of 
We have 
Using formula
Substitute the values in the given formula
Then,we get
Hence, the probability that an individual who has the symptoms and who reacts positively to the test actually has hepatitis =0.981
Answer:
y = 0.15x+77 is the equation linear connecting total cost y and miles driven x
Step-by-step explanation:
Given that the leasing company charged a flat rental fee for the week, plus a charge for each mile driven.
Let flat rental fee be c and cost per mile driven = m and miles driven = x
Total cost =y
Then y = mx+C is the linear equation.
to find m and c, we use the fact that y =110.30 when x = 222
i.e. 110.30 = c+222x
and similarly 99.05 = c+147x
Subtract to eliminate c
11.25 = 75 x
0.15 =x
Substitute in I equation
110.30 = c+222(0.15)
c = 77
y = 0.15x+77 is the equation linear connecting total cost y and miles driven x
The correct answer is C) n- 0.18
