⬇ Anyways, hey bud! The answer is down below ⬇

The answers are bolded so watch out for those!

Part 1

a. Complete this table showing some possible combinations of the number of each type of game being played;

Chess games (x) | Poker games (y)

1) 28 divided by 2 = 14 1) 8x4 = 32 people

2) 12x2=24 people 2) 36 divided by 4 = 9

3) 0 3) 15x4 = 60 people

4) 2x2=4 people 4) 56 divided by 4 = 14

Part 2 (Just a little extra ;] I love math :D)

b. There are 3 more games of poker being played than games of chess being played;

Y = x+3

60 = 2x+4y

Y = 8+3

Y = 11

60 = 2x+4(x+3)

60 = 2x+4x+12

$\frac{48}{6} = \frac{6x}{6}$

8 = x

8 games of chess are played and 11 games of poker.

Step-by-step explanation:

None, but on Part 1 you were actually correct! Good job!

You may have a great day! Bye! :D

The number of pages in the books in a library follow a normal distribution. The mean number of pages in a book is 150 with a sta

AysviL [449]

As the mean is E[X] =150 and $\sigma$ = 30, using the normal distribution to get the answer is just using Z. So, what we need is P(X<180).

$Z= \frac{x-E[X]}{\sigma } = \frac{180-150}{30} = \frac{30}{30} = 1$

P(x<180) = P(z< 1) = $\phi$ (1) = 0.8413.

Then, just multiplying the amount of books you have, which is 500, with the probability would give how many books are less than 180 pages, being:
$0.8413 * 500 = 420.65$
