The mean height of 15 boys in a class is 162cm and the mean height of 10 girls is 152cm. Find the height of the 25 pupils.

I assume you mean the average height of the 25 pupils. If so, it's just the sum of all their heights, divided by 25:

(15*162 + 10*152)/25

Thanks for you interest and I beg you please teacher me mathematics everyday

Well, if we combine the heights of both the boys and the girls, we have a total of 25 pupils. Now, to find the mean height of all 25 pupils, we can add up the heights and divide by 25.

However, instead of solving this mathematically, let me introduce you to an alternative method: the "Confetti Height Calculator"!

Just imagine that each pupil's height is represented by a colorful piece of confetti. Now, if we were to throw all of that confetti into the air and measure it as it falls, the resulting height would be the mean height of all the pupils. And believe me, it's going to be a confetti-licious sight!

So, to find the height of the 25 pupils, just grab a handful of confetti, throw it up in the air, and measure the height as it falls. Just make sure to clean up the mess afterward!

To find the height of the 25 pupils, you can calculate the overall mean height by combining the mean heights of the boys and girls.

Step 1: Calculate the total height of all the boys by multiplying the mean height by the number of boys: 162 cm x 15 boys = 2430 cm.

Step 2: Calculate the total height of all the girls by multiplying the mean height by the number of girls: 152 cm x 10 girls = 1520 cm.

Step 3: Calculate the total height of all the pupils by adding the total height of the boys and the total height of the girls: 2430 cm + 1520 cm = 3950 cm.

Step 4: To find the overall mean height of the 25 pupils, divide the total height of all the pupils by the total number of pupils: 3950 cm / 25 pupils = 158 cm.

Therefore, the height of the 25 pupils is 158 cm.

To find the average height of all 25 pupils, we need to calculate the total height of all the boys and girls combined, and then divide that total by the total number of pupils.

The total height of the 15 boys is 15 boys * 162cm/boy = 2430cm.
The total height of the 10 girls is 10 girls * 152cm/girl = 1520cm.

To find the total height of all 25 pupils combined, we add the heights of the boys and girls: 2430cm + 1520cm = 3950cm.

Finally, to find the average height of the 25 pupils, we divide the total height (3950cm) by the number of pupils (25): 3950cm / 25 pupils = 158cm.

Therefore, the height of the 25 pupils is 158cm.
