Answer:

The expected value is an expression of the weighted average and can be taken as the (arithmetic) mean

As the number of trials is increased in a binomial experiment, the expected values obtained, in each of the set of trials continuously tend to the theoretical expected value

Trey sold t-shirts and hats at a festival. His total profit was $106. He made a $4 profit for each t-shirt he sold. He also made

marta [7]

Answer:

18 t-shirts.

Step-by-step explanation:

Trey made a total profit $106 by selling t-shirts and hats. $34 of that profit was from selling hats, subtract 34 from 106 and you will get 72. So he made a profit of $72 in selling t-shirts. The t-shirts were $4 each, so if you divide 72 by 4 you will get 18. Meaning he sold 18 shirts.

<h3><u>Answer :</u><u>-</u><u> </u></h3>

<h3><u>Question :- </u></h3>

$find \: \frac{ - 4}{5} \times \frac{3}{7} \times \frac{15}{16} \times ( \frac{ - 14}{9} )$

<h2><u>Solution :- </u></h2>

<h3><u>First </u><u>way:</u></h3>

$\frac{ - 4}{5} \times \frac{3}{7} \times \frac{15}{16} \times ( \frac{ - 14}{9} )$

$= > \: ( - \frac {4 \times 3}{5 \times 7} ) \times ( \frac{15 \times ( - 14)}{16 \times 9}$

$= > \: \frac{ - 12}{35} \times ( \frac{ - 35}{24} ) = \frac{ - 12 \times ( - 35)}{35 \times 24} = \frac{1}{2}$

<h3><u>Second way : </u></h3>

$\frac{ - 4}{5} \times \frac{3}{7} \times \frac{15}{16} \times (\frac{ - 14}{9} )$

$= > \: ( \frac{ - 4}{5} \times \frac{15}{16} ) \times \binom{3}{7} \times ( \frac{ - 14}{9} )$

[ ↑ Using commutativity and Associativity ] ...

$\frac{ - 3}{4} \times ( \frac{ - 2}{3} ) = \frac{1}{2}$
