The solution would be like this for this specific problem:

Given:

                                                                                                                No (Did Not Lie)                Yes (Lied)

Positive Test Result                                                                                         10                           29

(Positive test indicated that the subject lied.)                      (false positive)                  (true positive)

Negative test result                                                                                         66                           18

(Polygraph test indicated that the subject did not lie.)     (true negative)                  (false negative)

 

Find:


The probability that all four test subjects had a true negative test result when they are randomly selected without replacement.

Formula:

(66/123) x (65/122) x (64/121) x (63/120) = 0.0793864272

 

Therefore, when they are randomly selected without replacement, the <span>probability that all four test subjects had a true negative test result is 0.079</span>.

Solve the equation x^2=26
Volgvan

Take the square root. The opposite of squaring something is taking the root :)

√x^2 = √26

x = √26

x = 5.099...

OR leave it if your teacher doesn't want a decimal since it can't be simplified anymore

Graph the function f(x)=−13x+1.
pogonyaev

Graph each points:

f(x) = -13x + 1

when x = 0, y = 1

f(0) = -13(0) + 1

f(0) = 0 + 1

f(0) = 1

when x = 1, y = -14

f(1) = -13(1) + 1

f(1) = -13 + 1

f(1) = -14

when x = 2, y = -25

f(2) = -13(2) + 1

f(2) = -26 + 1

f(2) = -25

etc.

Graph each point and connect them.
