The table below displays results from experiments with polygraph instruments. Find the positive predictive value for the test. That is, find the probability that the subject lied, given that the test yields a positive result.
_ No_(Did_Not_Lie) Yes_(Lied)
Positive_test_results 10 45
Negative_test_results 34 12
Using it's concept, the probability that the subject lied, given that the test yields a positive result is of 9/11 = 0.8182 = 81.82%.
What is a probability?The probability of an event in an experiment is calculated as the number of desired outcomes of the experiment divided by the number of total outcomes of the experiment.
In this problem, we want to find the probability that the subject lied, given that the test yields a positive result, hence:
The total outcomes are the tests resulting in a positive.The desired outcomes is the number of tests out of those positive in which the subject lied.From the table, we have that:
There were 10 + 45 = 55 positive test results.In 45 of those tests, the subject lied.Hence the probability is given as follows:
p = 45/55 = 9/11 (simplifying by 5)
p = 9/11 = 0.8182 = 81.82%.

Describe the function that this situation gives rise to. make a table for this function, sketch a graph for this function, and find an equation for this function. Is the function linear or not? How can you tell?
Step 1
Describe the function,
.
Let
x, the number of bags
shipping = 3 dollars
Charges=$12 for each bag, then
charges=12*x
Now, the total is
total=charges + shipping
total=12x +3
now, we have a function ( the total (y) depends on the number of bags)
[tex]y=12x+3[/tex]where
y is the total charge, and x is the numbers of bags
Step 2
assume values for x, replace and find y
x=-3
then y=12(-3)+3, y=-36+3, y=-33
so, when x=-3, y=-33
2
then y=12(-2)+3, y=-24+3, y=-21
so, when
x=-2, y=-21
1
then y=12(-1)+3, y=-12+3, y=-9
so, when
x=-1, y=-9
0
then y=12(0)+3, y=+3, y=3
so, when
x=0, y=3

contains (-6, 3)?
An equation in slope-intercept form for the line perpendicular to y = 3x + 9 that contains (-6, 3) is 3 = -1/3(-6) + 1.
What is slope-intercept form?The most "popular" type of a straight line is one with a slope-intercept. Due to its simplicity, this is helpful to a lot of students. The slope and y-intercept of the straight line can be easily determined or read off from this form, making it possible to describe its properties without having access to the graph.
The equation for a line written in slope-intercept form
y = mx + b
Where,
m is the slope, and b is the y-intercept.
We know that the slope of a line perpendicular to given equation becomes reciprocal with opposite sign.
So, here slope is 3 and in perpendicular line it will become -1/3.
Now we will go with slope-intercept form and put the values (-6, 3) as x and y in y = mx + b
⇒ 3 = -1/3(-6) + b
Lets solve for b
⇒ b = 3 - ( -1/3(-6))
= 3 - (2)
= 1
Now we have the desired equation
3 = -1/3(-6) + 1
Thus, An equation in slope-intercept form for the line perpendicular to y = 3x + 9 that contains (-6, 3) is 3 = -1/3(-6) + 1.

Correct
The second number is:
Correct
By using the elimination method, the numbers are 11 and 30
Consider the first number as x and the second number as y
Sum of 5 times the first number and 6 times the second number is 235
The linear equation will be
5x+6y = 235
The difference between 7 times the first number and 17 is 2 times the second number
7x-17 = 2y
Rearrange the terms
7x-2y = 17
The both equations are
5x+6y = 235
7x-2y = 17
Multiply the first equation by 2 and second equation by 6
10x+12y = 470
42x-12y = 102
Here we have to use the elimination method
Add both equation and y term will cancelled
10x+42x = 470+102
52x = 572
x = 11
Substitute the value of x in any equation
5x+6y =235
5(11)+6y = 235
