The Venn diagram is given below. Then the number of students who have brother and sister will be 6.
<h3>What are sets?</h3>
A set is a group of clearly specified components. The number of items in a finite set is denoted by a curly bracket.
In a class of 20 students:
11 have a brother, 9 have a sister, and 6 have neither.
Then the Venn diagram will be
11 – a + a + 9 – a = 20 – 6
20 – a = 14
a = 6
The Venn diagram is given below.

Answer:
337.5 and also 202.5
Step-by-step explanation:
do 8x = 540 since 5 and 3 are in a ratio... so you get 5x plus 3x. Then you solve for x and get 67.5..67.5 times 3 is 202.5 and 67.5 times 5 is 337.5.
Answer:
Volume of the given oblique cylinder = 36π units³
Step-by-step explanation:
Volume of the oblique cylinder = πr²h
Here, 'r' = Radius of the circular base
'h' = Height of the cylinder
For the given oblique cylinder,
Radius of the circular base = 3 units
Height of the cylinder = 4 units
Volume of the cylinder = π(3)²(4)
= 36π units³
Therefore, volume of the given oblique cylinder = 36π units³
If the number is a multiple of 8, it is divisible by 8.
The multiples of 8 are: 8, 16, 24, 32, 40, 48, 56, 64, 72, 80, 88... etc.
If a number is very big, let's say 176, see if you can deduct 80 from it. For this, 176 can be deducted by 80 twice, which will give you a remainder of 16 (I.e. 176 - 80 - 80 = 16". If this remainder (i.e. 16) is divisible by 8, 176 is divisible by 8.
For even larger numbers, try deducting 800, or even 8000.
Let's say you're trying to see if 2464 is divisible by 8. In this case, 2464 can be deducted by 800 thrice (I.e. 2464 - 800 - 800 - 800 = 64), and 64 is its remainder. Since 64 is divisible by 8, 2464 is divisible by 8.
Hope this helps! :)
