Answer:
The percentage of visitors who are truthful clickers and answered yes is 15%.
Step-by-step explanation:
Denote the events as follows:
<em>Y</em> = a visitor clicked Yes.
<em>N</em> = a visitor clicked No.
<em>R</em> = a visitor is a random clicker.
<em>T</em> = a visitor is a truthful clicker.
Given:

The law of total probability states that:

The probability of Y can be computed using the law above as
Compute the value of P (Y|T) as follows:

Percentage = 0.15 × 100 = 15%.
Thus, the percentage of visitors who are truthful clickers and answered yes is 15%.
Answer:
X=3,y=-2
Step-by-step explanation:
This is a simultaneous equation question and we will have to solve using substitution method
So let's solve
y=-2x+4...(1)
y=-2....(2)
Let's substitute (2) into (1)
-2=-2x+4
Substrate 4 from both sides
-6=-2x
Divide both sides by-2
x=3
Substitute the value of x in (1)
y=-2(3)+4
y=-6+4
y=-2
Therefore x is 3,y is -2

Step-by-step explanation:
Perhaps you want a graph of ...
x^2/49 +(y +1)^2/4 = 1
This is an ellipse centered at (x, y) = (0, -1) with a major axis in the x-direction of 14, and a minor axis in the y-direction of 4.
