Suppose that a polygraph is 90% accurate (it will correctly detect 90% of people who are lying and it will correctly detect 90% of people who are telling the truth). The employees of a company are given a polygraph test during which they are asked whether they use drugs. All employees say that they do not use drugs. Assume that anyone whom the polygraph operator finds untruthful is accused of lying. Complete parts (a) and (b). Users Nonusers Total Test finds employee lying Test finds employee truthful Total a. How many employees are accused of lying? nothing How many employees accused of lying were actually lying? nothing How many employees accused of lying were telling the truth? nothing What percentage of those accused of lying were falsely accused? nothing% (Round to the nearest tenth as needed.) b. How many employees are found truthful? nothing How many employees that are found truthful were actually truthful? nothing What percentage of those found truthful really were truthful? nothing% (Round to the nearest tenth as needed.)

the value of v.w= -12.

step-by-step explanation:

we are given three vector r,v and w as:

r = < 5, -5, -2> ; v = < 2, -8, -8> ; w = < -2, 6, -5>

we know that r,v and w could also be represented as:

r=5i-5j-2k

v=2i-8j-8k

and w= -2i+6j-5k

where i,j and k are the unit vectors of x,y and z-axis respectively.

also we know that it has the following property:

i.i=1 ; j.j=1; k.k=1

and i.=j.i=i.k=k.i=j.k=k.j=0

i.e. when we multiply two vectors or we find it's dot product we need to only multiply the components of x coordinates with each other; y with each other and z with each other.

hence, v.w= (2i-8j- -2i+6j-5k)

                  = 2×(-2)+(-8)×(6)+(-8)×(-5)

                  = -4-48+40

                  = -12

hence, v.w= -12

so a parallelogram is just like a square base times height. multiply 40 and 39 to get 1560 inches.

a triangle is base times height divided by two. so multiply 7.9 and 5 and then divide it by 2 to get 19.75inches.

the kite can be split into two separate triangles and added together to get the total area. 30 x 4 /2 which equals 60. make sure to double it for the two triangles making 120.

6/20

step-by-step explanation:

the answer is 8/21
