Answer:

490 pens
510 pencils

Step-by-step explanation:

Let p represent the number of pens Nick sold. Then the revenue is ...

0.10p +0.05(1000 -p) = 74.50

0.05p = 24.50 . . . . . . eliminate parentheses, subtract 50

p = 490 . . . . . . . . . . . . multiply by 20

The number of pencils sold is then ...

pencils = 1000 -490 = 510

Nick's Printing Press sold 490 pens and 510 pencils.

Answer:

We conclude that expected value of this game is -0.865$.

Step-by-step explanation:

We know that in a lottery game, a player picks six numbers from 1 to 27.

We know that

$C_6^{27}=296010$

As there is only one advantageous combination, we conclude that the number of non-winning combinations is 296009.

He can win 40,000 dollars.

We calculate:

$E(X)=\frac{1}{296010}\cdot 40000\$- \frac{296009}{296010}\cdot 1\$\\\\E(X)=\frac{40000-296009}{296010}\, \$\\\\E(X)=-0.865\, \$$

We conclude that expected value of this game is -0.865$.
