A stockbroker estimates that at the end of the year, there is a 40% chance a stock will be worth $50,

nadya68 [22]

The expected value that this broker assign to this stock's end-of-the-year price is $58.50.

Using this formula

Expected value=Stock worth at $50+ Stock worth at $60+ Stock worth at $70

Where:

Stock worth at $50=40% chance

Stock worth at $60=35% chance

Stock worth at $70=25% chance

Let plug in the formula

Expected value=(40%×$50)+($35%×$60)+($25%×$70)

Expected value=$20+$21+$17.5

Expected value=$58.50

Inconclusion the expected value that this broker assign to this stock's end-of-the-year price is $58.50.

Find the coordinates of the point P at an angle of 45 degrees on a circle of radius 4.5. Round your answer to 3 decimal places.

Varvara68 [4.7K]

$\bf sin(\theta)=\cfrac{y}{r}
\qquad 

% cosine
cos(\theta)=\cfrac{x}{r}\quad 
\begin{cases}
r=radius=hypotenuse\\
x=adjacent\\
y=opposite\\
\theta=angle
\end{cases}\\
-----------------------------\\
thus
\\\\

\begin{cases}
r=4.5\\
\theta=45^o
\end{cases}\implies 
\begin{cases}
sin(\theta)=\cfrac{y}{r}\to sin(45^o)=\cfrac{y}{4.5}\to 4.5\cdot sin(45^o)=y
\\\\
cos(\theta)=\cfrac{x}{r}\to cos(45^o)=\cfrac{x}{4.5}\to 4.5\cdot cos(45^o)=x
\end{cases}
\\\\
P\ is \ at\quad (x,y)$

the angle is in degrees, thus, when taking either sine or cosine, make sure your calculator is in Degree mode

1 1/3 divided by 3 + 1/3

Phantasy [73]

The first step to solve this problem is to convert the first mixed number to an improper fraction.
$\frac{4}{3}$ ÷ 3 + $\frac{1}{3}$
Dividing is equivalent to multiplying with the reciprocal value,, so next you will need to change the signs.
$\frac{4}{3}$ x $\frac{1}{3}$ + $\frac{1}{3}$
Multiply the fractions
$\frac{4}{9}$ + $\frac{1}{3}$
Finally,, add the two fractions together to get your final answer
$\frac{7}{9}$
This means that the correct answer to your question is $\frac{7}{9}$ .
Let me know if you have any further questions
