Answer:
I believe it is true
Step-by-step explanation:
I'm not 100% sure but I am like 85% sure that it is true.
For this case we have that the inverse variation is defined as:
Where:
k: It is the constant of proportionality
According to the statement we have:
We find the constant of proportionality:
Then we find the value of x when :
Answer:
Answer:
The probability that at least one of the children get the disease from their mother is P=0.7125.
Step-by-step explanation:
This can be modeled as a binomial random variable.
The parameter p=0.34 is the probability of a child being infected, and is constant and independent of the other events.
The parameter n=3 is the number of children (sample size).
Then, we have to calculate the probabilty that at least one of the children get the disease from their mother. That is:
The probability of exactly k children being infected can be calculated as:
Then, the easiest way to calculate this probability is using the complement: the value of the probability is 1 (or 100%) less the probability that no children gets infected.
(x+2)(x+1) = x^2 + x + 2x + 2
simplify it
x^2 + 3x + 2
Jude's mistake is that he added the exponents and multipled the numerators and the denomerators before doing the exponents first.
correct way:
1/4 times 1/2 times 1/8
which equals 1/64
