Write the mixed number as a percent <br><br> 2 41/50
ehidna [41]

Answer:

∴ 2 \frac{41}{50}  = 282 %

Step-by-step explanation:

2 \frac{41}{50}

= [( 2 × 50) + 41] ÷ 50

=  ( 100 + 41) ÷ 50

= \frac{141}{50}

=( \frac{141 }{50} ) × \frac{2}{2}

= \frac{282}{100}

= 282 %

∴ 2 \frac{41}{50}  = 282 %

Prove the statement holds for all positive integers:<br><br> 2 + 4 + 6 + ... + 2n = n² + n
crimeas [40]

Proving a relation for all natural numbers involves proving it for n = 1 and showing that it holds for n + 1 if it is assumed that it is true for any n.

The relation 2+4+6+...+2n = n^2+n has to be proved.

If n = 1, the right hand side is equal to 2*1 = 2 and the left hand side is equal to 1^1 + 1 = 1 + 1 = 2

Assume that the relation holds for any value of n.

2 + 4 + 6 + ... + 2n + 2(n+1) = n^2 + n + 2(n + 1)

= n^2 + n + 2n + 2

= n^2 + 2n + 1 + n + 1

= (n + 1)^2 + (n + 1)

This shows that the given relation is true for n = 1 and if it is assumed to be true for n it is also true for n + 1.

<span>By mathematical induction the relation is true for any value of n.</span>
