Question

Apply sub-goals to find the percentage of perfect squares between 1 and 100, inclusive, that are odd. Round to the nearest percentage if necessary.

Hint: Consider five sub-goals. 1) List all perfect squares from 1 to 100. 2) Count the number of odd squares. 3) Divide the number of odd squares by the total number of squares. 4) Convert the fraction to a percentage. 5) If needed, round your answer to the nearest percentage.

Answer 1

what on earth is a "sub goal"?

Answer 2

That is what I was wondering.

Answer 3

there are not so many perfect squares that you cannot list them all
\[1,4,9,16,25,36,49,64,81,100\]

Answer 4

out of those ten, i count 5 odd ones and 5 even ones

Answer 5

making half odd, and half even
if you want a percent, half is \(50\%\)

Answer 6

the answers that it says it could be are :

40%
50%
56% and
25%

so would it be 25, because 25 is a perfect square? or....

Answer 7

they are asking for the percent of the perfect squares that are odd
half are odd, and half is \(50\%\) i.e. \(\frac{5}{10}=.5=50\%\)

Answer 8

oh gosh, okay I think that is right then. That is good with me.

Answer 9

no, not \(25\%\) because 25 is a perfect square. \(25\%\) means \(.25\)
