What is wrong with this "proof"? "Theorem" For every positive integer n,n i =1 i = (n + 1 2 ) 2 /2. Basis Step: The formula is t

creativ13 [48]

Answer:

The basis step is not even true.

Step-by-step explanation:

The basis step would be for n = 1.

If the basis step was true then you would have that.

$\sum\limits_{i=1}^{1} i = \frac{(1+1/2)^2}{2}$

Now. When you say

$\sum\limits_{i=1}^{1} i$

That's just a fancy way of writing 1.

On the other hand

$\frac{(1+1/2)^2}{2} = \frac{9}{4} = 2.25$

Therefore

$1 \neq 2.25$

And the basis hypothesis is false.

Shelby spends 2/7 of her salary on her monthly rent and has $3455 left over. How much does she spend on her rent each month?

Zepler [3.9K]

Answer:

$1382

3455 is 5/7 of salary so divide 3455/5 = 691

then multiply 691x2 because rent is 2/7 of salary

691x2 = 1382
