Answer:
f(-4) = 4
f(-1) = 0
f(-6) = -4
Step-by-step explanation:
Since functions, f(x), are interpreted as "The function of x," then it means that the values inside the parenthesis of the f(x) are the x values. Looking at the graph, the following functions are located as the curve crosses the given points on the graph:
f(-4) = 4
f(-1) = 0
f(-6) = -4
Answer:
0.967 = 96.7% probability the rock sample actually contains raritanium
Step-by-step explanation:
Conditional Probability
We use the conditional probability formula to solve this question. It is
In which
P(B|A) is the probability of event B happening, given that A happened.
is the probability of both A and B happening.
P(A) is the probability of A happening.
In this question:
Event A: Positive reading
Event B: Contains raritanium
Probability of a positive reading:
98% of 13%(positive when there is raritanium).
0.5% of 100-13 = 87%(false positive, positive when there is no raritanium). So
Positive when there is raritanium:
98% of 13%
What is the probability the rock sample actually contains raritanium?
0.967 = 96.7% probability the rock sample actually contains raritanium
