Answer:
Step-by-step explanation:
We write a function f(x) which gives the values of the function that are dependent on the independent variable "x".
Given: The number of miles on the odometer can be represented by the equation y = x + 40, 000, where y is the number of miles on the odometer, and x is the number of miles you have driven it.
Here y is dependent on x, so we replace y by f(x), then we get
which is the required answer.
Answer:
Step-by-step explanation:
Let X be the number of persons out of 12 who have RH negative blood.
X is binomial since each person is independent of the other to have Rh negative blood.
n =12
a) What is the probability that exactly 5 of those patients will have Rh negative blood?
P(X=5) =
b) What is the probability that at least 3 of them will have Rh negative blood?
=0.6397
c) What are the expected number and standard deviation of the number of these patients with Rh negative blood?
E(X) = np =
Var(x) = npq =
Std dev =
