Answer:
Step-by-step explanation:
We want to find the inverse of
We interchange x and y.
We need to solve for y, so let us multiply through by 2.
Subtract 6 from both sides.
Therefore the required inverse is

Hi there
How to find unit rates?
To find the unit rate, divide the numerator and denominator of the given rate by the denominator of the given rate.
You have to first solve for the slop using the equation y2-y1/x2-x1 and then you plug the slope (m) into y=mx+b using one of the x and y values from any of the points above and then lastly solve for b.
For these particular points it would look like this... 11-7/5-3 =2 (slope/m)
7=2(3)+b
7=6+b
7-6=b
1=b
Final equation: y=2x+1
Answer:
There is a 13.40% probability that a message is spam, given that it contains the word "text" (or "txt").
Step-by-step explanation:
The problem states that
There are 5574 messages.
There are 747 messages that are spam.
Every message contains the word text.
Bayes rule:
What is the probability of B, given that A?
In this problem, we have that
A is containing the word text. So
So
is containing the word text and being a spam message. So:
There is a 13.40% probability that a message is spam, given that it contains the word "text" (or "txt").
