Answer:

The Random sampling method is being used.

Step-by-step explanation:

Consider the provided statement.

Random sample: If we select the subset of the individuals from the given set and the probability of getting selected for each individual is same, then it is known as the random sample.

There are 1000 students out of which 500 are boys and 500 are girls.

The probability of selecting a boy and a girl is the same.

If we pull out 100 names then the probability will be the same for the boys as well as for the girls.

Here, for each individual, the probability is the same.

Thus, the Random sampling method is being used.

What is the expanded form of 340,729​
babymother [125]

Answer:

(300,000 + 20,000 + 0 + 700 + 40 + 9)

Step-by-step explanation:

The expanded form of 320, 749

Segmenting each digit in the figure based on its place value :

3 = 100 thousand place = 3 * 100,000 = 300000

2 = ten thousand place = 2 * 10,000 = 20000

0 = thousand place = 0 * 1,000 = 0

7 = hundred place = 7 * 100 = 700

4 = tens place = 4 * 10 = 40

9 = unit place = 9 = 9

(300,000 + 20,000 + 0 + 700 + 40 + 9)

viva [34]

Answer:

Thus Volume of pool is 297.67m^{3}

<u><em /></u>

<u><em>GIVEN:</em></u> A swimming pool 20.6 m long 8.5 m wide and height 1.7 m

<u><em>TO FIND:</em></u> Volume of water needed to fill it.

<u><em>SOLUTION:</em></u>

<em>Length</em> = 20.6 m

Width = 8.5 m

<em>Height = </em>1.7 m

<em>Volume = L × B × H</em>

<em>→ </em>1.7\times20.6\times8.5<em />

<em>→ </em>297.67m^{3}<em />

<em />

Thus volume of pool is 297.67m^{3}

<em>I hope this helps you </em>
