4. Media aritmetica a numerelor 24, 26 si 28 este:

26

24

28

78

The given numbers are 24, 26, and 28. To find the arithmetic mean (average), we add up all the numbers and divide the sum by the total count of numbers. Adding 24, 26, and 28 gives us 78. Since there are three numbers, we divide 78 by 3 to get the arithmetic mean. Therefore, the arithmetic mean of 24, 26, and 28 is 26.

5. Doua ore reprezinta:

7200 s

3600 s

120 s

360 s

The correct answer is 7200 s. This is because there are 60 minutes in an hour and 60 seconds in a minute. Therefore, 2 hours would be equal to 2 * 60 minutes = 120 minutes. And 120 minutes * 60 seconds = 7200 seconds.

Explanation

The correct answer is 7200 s. This is because there are 60 minutes in an hour and 60 seconds in a minute. Therefore, 2 hours would be equal to 2 * 60 minutes = 120 minutes. And 120 minutes * 60 seconds = 7200 seconds.

6. Daca un produs ce costa 200 lei se scumpeste cu 20%, el va costa:

220

400

440

240

If a product that costs 200 lei increases in price by 20%, the new price will be 240 lei. This can be calculated by multiplying the original price (200) by the percentage increase (20%) and adding the result to the original price. So, 200 + (200 * 20%) = 240.

Explanation

If a product that costs 200 lei increases in price by 20%, the new price will be 240 lei. This can be calculated by multiplying the original price (200) by the percentage increase (20%) and adding the result to the original price. So, 200 + (200 * 20%) = 240.

7. Care din urmatoarele numere este mai mare? 2,34 ; 2,(34) ; 2,(3) ; 2,304

2,34

2,(34)

2,(3)

2,304

The correct answer is 2,(34). This is because the number 2,(34) represents a repeating decimal, where the digits 34 repeat infinitely. This means that the number is larger than the other options given, which are all either terminating decimals or non-repeating decimals.
