Nataliya [291]

Answer:

100,000

200

65,610

Step-by-step explanation:

Given that:

Identification number = 5 digits

A.) number of identification numbers possible :

Possible digits : 0, 1, 2, 3, 4, 5, 6, 7, 8, 9

Total digits possible = 10

Each digit can be any of the 10;

Hence,

10 * 10 * 10 * 10 * 10 = 100,000 possibilities

B.) How many of them begin with either 023 or 003

023 or 003

0 or 0 = 1 option

2 or 0 = 2 options

3 or 3 = 1 option

Other digits will have any of the 10 options :

1 * 2 * 1 * 10 * 10 = 200

3.) if no two digits that follow each other are the same, then only the first digit has 10 options with the other 4 each having 9

10 * 9 * 9 * 9 * 9 = 65,610

Select the correct answer. The volume of one of the Great Lakes is 3. 5 × 103 cubic kilometers. If there are 6. 3 × 107 fish in

valentinak56 [21]

The average number of fish per cubic kilometer is $1. 8 \times 10^4$ .

The correct option is B.

Given

The volume of one of the Great Lakes is 3.5 × 103 cubic kilometers.

The number of fish in the lake = 6. 3 × 107.

<h3>What is the average value?</h3>

The average is the middle value of the given data set and is calculated by adding up all the numbers and dividing the result by the total quantity of figures added.

The average number of fish per cubic kilometer is given by;

$\rm \text{The average number of fish per cubic kilometer}= \dfrac{Number \ of \ fish \ in \ lake}{Total \ volume \ of \ lake}$

Substitute all the values in the formula;

$\rm \text{The average number of fish per cubic kilometer}= \dfrac{Number \ of \ fish \ in \ lake}{Total \ volume \ of \ lake}\\\\ \text{The average number of fish per cubic kilometer}= \dfrac{6.3\times 10^7}{3.5\times 10^3}\\ \text{The average number of fish per cubic kilometer}= 1.8 \times 10^4$

Hence, the average number of fish per cubic kilometer is $1. 8 \times 10^4$ .
