Solution :
It is given that :
P (positive | Has disease) = 0.7
P (positive | No disease) = 0.08
P (has disease) = 0.18
P (No disease) = 1 - 0.18
= 0.82
Now if test administered to the individual is positive, the probability that the person actually have the disease is
P (Has disease | positive) 
......(1)
The P(positive) is,
= P(positive | has disease) x P(Has disease) + P(positive | no disease) x P(No disease)
= 0.7 (0.19) + 0.04 (0.81)
= 0.1654
Now substituting the values in the equation (1), we get
P (Has disease | positive)
= 0.8041
Answer:
24
Step-by-step explanation:
The multiples of 8 are 8,16,24,32 etc. and the multiples of 6 are 6,12,18,24,30, ect. The answer is 24 because it is the lowest multiple of 6 that crosses with multiples of 8.
Answer:
t = 6162 years
Step-by-step explanation:
Apparently you are asked to use the constant k = 0.0001 instead of the most common 0.00012. We'll answer the problem using such number you typed, but make sure that there is no omission in your typing.
The equation to use is that for carbon decay:
If the skull contains 54% of its original amount of C14, then that means that :
we use this to solve for the time (t) in our equation:
which rounded to the nearest year as requested gives :
t = 6162 years
Find an x value and f(x) is just it's y value. we can start with x=0
when x=0 y= -3
when x= 2 y= -2
and so on, choose easy to read numbers.
you can finish the rest, let me know if you wanna check your answers or if you are stuck.
