Answer:

Step-by-step explanation:

Why are you asking? Why isn't your friend?

The diagram assumes that the angle on the lower left of the triangle is a right angle. If it is not, then I don't think there is a way that this can be solved.

Tan(A) = opposite / adjacent

opposite = 7

Adjacent = 4

Tan(A) = 7/4 = 1.75

A = inverseTan (1.75)

A = 60.60 degrees

An employee suspected of having used an illegal drug is given two tests that operate independently of each other. Test A has pro

puteri [66]

Answer:

0.02 or 2%

Step-by-step explanation:

The probability that test A is negative if the illegal drug has been used (P(A|N)) is 0.1 while the probability that test B is negative if the illegal drug has been used (P(B|N)) is 0.2.

Therefore, the probability that neither test is positive if the illegal drug has been used is:

$P(A \cap B|N) = P(A|N)* P(B|N) = 0.1 *0.2\\P(A \cap B|N) = 0.02$

There is a 0.02 or 2% probability that neither test is positive if the illegal drug has been used.

tamaranim1 [39]

So it went from 30 to 35, or 5 bucks, if we take 30 to be the 100%, what is 5 off of it in percentage?

$\bf \begin{array}{ccll}
amount&\%\\
\text{\textemdash\textemdash\textemdash}&\text{\textemdash\textemdash\textemdash}\\
30&100\\
5&p
\end{array}\implies \cfrac{30}{5}=\cfrac{100}{p}\implies p=\cfrac{5\cdot 100}{30}$
