All the pupils at a primary school come from one of three villages: Elmswell, Haughley or Woolpit. 1/4 of the pupils come from E

Jlenok [28]

Answer:

680

Step-by-step explanation:

Given that:

All the pupils at a primary school come from one of three villages: Elmswell, Haughley or Woolpit.

$\frac{1}{4}$ of the pupils come from Elmswell

$\frac{3}{5}$ of the pupils come from Haughley

102 pupils come from Woolpit.

To find:

Total number of pupils in the school.

Solution:

Let total number of pupils = $100x$

So, number of pupils that come from Elmswell = $\frac{1}{4}$ of 100x

$\dfrac{1}{4} \times 100x\\\Rightarrow 25x$

And, number of pupils that come from Haughley= $\frac{3}{5}$ of 100x

$\dfrac{3}{5} \times 100x\\\Rightarrow 60x$

Number of pupils that come from Woolpit = $100x - 25x - 60x \Rightarrow 15x$

As per given statement:

$15x = 102\\\Rightarrow x =6.8$

Number of pupils from Elmswell = 25x = 25 $\times$ 6.8 = 170

Number of pupils from Haughley = 60x = 60 $\times$ 6.8 = 408

Total number of pupils at the school = $100x \Rightarrow 100 \times 6.8=680$

Construct a truth table for the statement: (p v q) v (~p ^ q) -> q

Gnom [1K]

Step-by-step explanation:

We have the following statement $(p\lor q)\lor(\lnot p \land q) \rightarrow q$

A truth table shows how the truth or falsity of a compound statement depends on the truth or falsity of the simple statements from which it's constructed.

The simple statements from the statement given are:

$\lnot p$ , $p\lor q$ , $\lnot p \land q$ , and $(p\lor q)\lor(\lnot p \land q)$

This is the truth table.

In how many ways can ann, bob, chuck, don and ed be seated in a row such that ann and bob are not seated next to each other?

balandron [24]

The 5 people can seat in a row in 5! ways
But we need to exclude the ways that ann and bob are seated next to each other which is = 4! * 2!

So, the number of ways can ann, bob, chuck, don and ed be seated in a row such that ann and bob are not seated next to each other = 5! - 4! * 2! = 72

=====================================================

Another solution:

If ann seated in one of the ends, the number of ways = 3*2

If ann didn't seat in one of the ends , the number of ways = 2*3

So, the total number of ways that can ann, bob be seated = 3*2 + 2*3 = 12

The remaining persons can seat with a number of ways = 3! = 6
So, the total ways that the five persons can seat = 12*6 = 72
