Two coins are flipped. You win $3 if either two heads or two tails turn up; you lose $4 if a head and a rail turn up. What is th
Lyrx [107]

Answer:

Step-by-step explanation:

It's too bad about this problem. It's a fair game if you get paid the same amount that you have to pay if you lose.

You win 2 ways

  • H - H
  • T - T
  • Probability 1/2

You lose 2 ways.

  • H - T
  • T - H
  • Probability 1/2

Expectation

E = 1/2 * 3 - 1/2 * 4

E = 1.5 - 2

E = -0.5

Which means that you should expect to lose 0.5 dollars every time you play this dreadful game.

Savings account100 shares x $9.75 = $975, then multiplied by 0.045 will result to $43.89.
Stock100 shares x $9.75 = $975, then multiplied by 0.08 will result to $78.00.
So, the difference between your stocks and savings account by end of the year is $34.11 ($78.00 deducted by $43.89).Your stock is gaining higher APR by $34.11 than what's calculated in your savings account.

Use the Law of Sines to find the measure of angle J to the nearest degree.
rjkz [21]
\bf \textit{Law of sines}
\\ \quad \\
\cfrac{sin(\measuredangle A)}{a}=\cfrac{sin(\measuredangle B)}{b}=\cfrac{sin(\measuredangle C)}{c}\\\\
-----------------------------\\\\
\cfrac{sin(J)}{9.1}=\cfrac{sin(97^o)}{11}\implies sin(J)=\cfrac{9.1\cdot sin(97^o)}{11}
\\\\\\
\textit{now taking }sin^{-1}\textit{ to both sides}
\\\\\\
sin^{-1}\left[ sin(J) \right]=sin^{-1}\left( \cfrac{9.1\cdot sin(97^o)}{11} \right)
\\\\\\
\measuredangle J=sin^{-1}\left( \cfrac{9.1\cdot sin(97^o)}{11} \right)
