Answer:
The probability that a birth was to a teen mother if we know that the pregnancy was unintended is 0.1942.
Step-by-step explanation:
Denote the events as follows:
<em>T</em> = birth was to a teen mother
<em>Y</em> = birth was to a young-adult mother
<em>A</em> = birth was to an adult mother
<em>U</em> = a birth was unintended
<em>I</em> = a birth was intended.
<u>Given:</u>
P (T) = 0.09
P (Y) = 0.24
P (A) = 0.67
P (I | T) = 0.23
P (U | T) = 0.77
P (I | Y) = 0.50
P (U | Y) = 1 - P (I | Y) = 0.50
P (I | A) = 0.75
P (U | A) = 1 - P (I | A) = 0.75 = 0.25
Consider the tree diagram below.
According to the Bayes' theorem,
Using the Bayes' theorem compute the probability that a birth was to a teen mother if we know that the pregnancy was unintended as follows:
The probability that a birth was to a teen mother if we know that the pregnancy was unintended is 0.1942.
For the first point, remember this simple rule: every exponential function always returns
when evaluated at
. In fact,
for every possible base
.
So, we can see that the graph of the exponential passes through the point where
appears to be between 1 and 2. So, the only feasible option would be
, because it passes throught the point
because
.
The other functions are wrong because:
would pass through
, which would be between 0 and 1 on the y axis
would pass through
, which would be between 2 and 3 on the y axis
would pass through
, which would be between 0 and 1 on the y axis
As for the second question, you simply have to plug in the values: the function
means that you have to choose an input, x, and use it as exponent for 7. So, if you choose x=2, it means that you have to give exponent 2 to 7, i.e. you replace the x with the specific value, 2.
So, the expression becomes
