To go from A to A ', we shift 6 units to the right. Put another way, shift every point that makes up figure A and you get to figure A '.

In terms of coordinate geometry, we're adding 6 to each x coordinate. The y coordinate stays the same.

What is the total number of digits required in numbering the pages of a book, which has 1,724 pages?

Alex Ar [27]

Answer:

5789 digits

Step-by-step explanation:

Given that the number of pages ares: 1,724

As we know that:

(from 1 - 9) there are 9 one-digit numbers
(from 10- 99) there are 90 two-digit numbers
(from 100 - 999) there are 900 three-digit numbers
(from 1,000 - 1,724) there are 725 four-digit numbers

So the total are:

$= 9(1)+90(2)+900(3)+725(4)\\\\= 9+180+2,700+2,900\\\\= 5,789\ digits$

A roulette wheel has the numbers 1 through 36, 0, and 00. A bet on five numbers pays 6 to 1 (that is, if one of the five numbers

tatiyna

Answer:

5 cents

Step-by-step explanation:

So the roulette wheel would have a total of 38 numbers, which means 38 different possible cases. Since you are allowed to bet on 5 numbers, the chance to win this is 5 out of 38 and to lose this is 33 out of 38.

If you win, you get 1 + 6 = 7 dollar, and if you lose, you lose 1 dollar.

Therefore the expected amount out of this game is:

$E = 7\frac{5}{38} - 1\frac{33}{38} = \frac{35}{38} - \frac{33}{38} = \frac{2}{38} = \frac{1}{19} = \$0.0526$
