A company administers an "aptitude test for managers" to aid in selecting new management trainees. Prior experience suggests tha

RoseWind [281]

Answer:

0.94

Step-by-step explanation:

The question after this basically is:

<em>"If the applicant passes the "aptitude test for managers", what is the probability that the applicant will succeed in the management position?"</em>

<em />

So,

P(successful if hired) = 60% = 0.6 [let it be P(x)]

P(success at passing the test) = 85% = 0.85 [let it be P(y)]

P(successful and pass the test) = P(x) + P(y) -[P(x)*P(y)]

So,

P(successful and pass the test) = 0.6 + 0.85 - (0.6*0.85) = 0.94 (94%)

in 2 h, kelly laid new floor tile over 1/5 of the room. when she was joined by annette, the rest of the work was completed in 3h

jeyben [28]

Answer: Annette will take 6 hours to do the entire job alone.

Step-by-step explanation:

Given: Time taken by Kelly to do $\dfrac{1}{5}$ of job = 2 hours

i.e. Time for complete job done alone by Kelly = $5\times2=10\ hours$

Rest of work = $1-\dfrac{1}{5}=\dfrac{4}{5}$ of the job

$\dfrac{4}{5}$ of the complete job done by both Kelly and Annette in 3 hours

Time would be taken by then to do entire job together = $3\times\dfrac{5}{4}=3.75\ hours$

Let t be the time taken by Annette to do job alone.

Then, as per situation

$\dfrac{1}{3.75}=\dfrac{1}{10}+\dfrac{1}{t}\\\\\Rightarrow\ \dfrac{1}{t}=\dfrac{1}{3.75}-\dfrac{1}{10}\\\\\Rightarrow\ \dfrac{1}{t}=\dfrac{4}{15}-\dfrac{1}{10}\\\\\Rightarrow\ \dfrac{1}{t}=\dfrac{1}{6}\\\\\Rightarrow\ t=6$

hence, Annette will take 6 hours to do the entire job alone.

Given the function f(x) = −5x2 − x + 20, find f(3). −28 −13 62 64

Katyanochek1 [597]

Answer:

Option (a) is correct.

The value of given function $f(x)=-5x^2-x+20$ at x = 3 is -28

Step-by-step explanation:

Given : Function $f(x)=-5x^2-x+20$

We have to find the value of given function at x = 3

Consider the given function $f(x)=-5x^2-x+20$

Since, we have tof ind the value of function at x = 3

Put x = 3 in given function f(x)

$f(3)=-5(3)^2-(3)+20$

Simplify, we have,

$f(x)=-45-3+20=-28$

Thus, the value of given function $f(x)=-5x^2-x+20$ at x = 3 is -28
