A seven digit telephone number is of the form ABC-DEFG. In one particular state, the

yKpoI14uk [10]

Answer:

Choice B. 5,114,880 (There's a digit missing in the problem.)

Step-by-step explanation:

You must see the number of choices you have for each digit. Then you multiply all those numbers of choices together.

There are 7 digits in the phone number, so you will be multiplying 7 numbers together.

_ * _ * _ * _ * _ * _ * _

First digit: any digit except 8 and 9.

Since you exclude 2 digits from the 10 possible digits, there are 8 choices left.

8 * _ * _ * _ * _ * _ * _

Second and third digits: any digit from 1 and 8.

Any digit from 1 to 8 means: 1, 2, 3, 4, 5, 6, 7, 8. That means there are 8 choices.

8 * 8 * 8 * _ * _ * _ * _

Last four digits: no restrictions (for now), so there are 10 choices for each digit. We will deal with the restriction of 4 equal digits below.

8 * 8 * 8 * 10 * 10 * 10 * 10

The product of the 7 numbers above is:

8 * 8 * 8 * 10 * 10 * 10 * 10 = 5,120,000

The last 4 digits cannot all be thee same. There are 10 ways they can all be the same: 0000, 1111, 2222, 3333, 4444, 5555, 6666, 7777, 8888, 9999.

Each of the combinations of the first 3 digits cannot have 10 combinations of equal digits.

The number of combinations of the first 3 digits is: 8 * 8 * 8 = 512.

Each of these 512 combinations cannot have 10 combinations of equal digits for the last 4 digits. 512 * 10 = 5120.

We must subtract 5120 from 5,120,000 to find the final answer.

5,120,000 - 5120 = 5,114,880

What is the product in simplest form? −611⋅34

Anton [14]

<u>Correct Question:</u>

What is the product in simplest form?

$-\frac{6}{11} \times \frac{3}{4}$

<u>Answer:</u>

$-\frac{9}{22}$ is the product in simplest form

<u>Step-by-step explanation:</u>

We can find the simplest form of solving two fractions. So, to make the fractions multiplication simple, multiply two fractions in the numerator and divide it by the denominators of the two fractions. In the given case,

$-\frac{6}{11} \times \frac{3}{4}$

To simplify, multiply both 6 and 3 in numerator and multiply 11 and 4 in denominator of two fractions. So, we get

$-\frac{18}{44}$

To simplify the above, divide 18 and 44 by their greatest common factor, which is 2. By doing this, we get

$-\frac{9}{22}$
