An experiment consist of drawing 1 card from a standard 52 -card deck. Let E be the event that card drawn is a 2. Find P(E').

Snezhnost [94]

The sum of the probabilities of an event E and its complement E' is 1,

that is P(E)+P(E')=1, where E' is "not E".

The event E can happen in 4 ways, because there are four 2's that can be drawn.

P(E)=n(E)/52=4/52=0.08

P(E')=1-P(E)=1-0.08=0.92

Answer: 0.92

If sine of x equals square root of 2 over 2, what is cos(x) and tan(x)? Explain your steps in complete sentences. (10 points)

tensa zangetsu [6.8K]

$\bf sin(\theta)=\cfrac{opposite}{hypotenuse}
\qquad
cos(\theta)=\cfrac{adjacent}{hypotenuse}
\quad 
% tangent
tan(\theta)=\cfrac{opposite}{adjacent}\\\\
-------------------------------\\\\$

$\bf sin(x)=\cfrac{\sqrt{2}}{2}\cfrac{\leftarrow opposite}{\leftarrow hypotenuse}\impliedby \textit{now, let's find the adjacent side}
\\\\\\
\textit{using the pythagorean theorem}\\\\
c^2=a^2+b^2\implies \pm\sqrt{c^2-b^2}=a\qquad 
\begin{cases}
c=hypotenuse\\
a=adjacent\\
b=opposite\\
\end{cases}
\\\\\\
\pm\sqrt{(2)^2-(\sqrt{2})^2}=a\implies \pm\sqrt{4-2}=a\implies \pm\sqrt{2}=a$

now, the adjacent side, or the x-coordinate for the angle, can be negative and positive, is positive in the I quadrant and negative in the II quadrant, with a positive y-coordinate... so it can be either, the +/- one.

$\bf cos(x)=\cfrac{\pm\sqrt{2}}{2}\qquad tan(x)=\cfrac{\frac{\sqrt{2}}{2}}{\pm\frac{\sqrt{2}}{2}}\implies tan(x)=\pm 1$

vredina [299]

The answer is 25 feet because 5*5=25 you wont be multiplying it all by 5 because that's just when you're trying to find out the perimeter
