You only flip the second fraction.
It's important to say that a conjecture, in mathematics, it's a conclusion based on certain evidence and it's supposed to be true. In this case, we have the conjecture: <em>The difference between any two whole numbers is a whole number. </em>
<em />
<em />
When you have a conjecture, the first thing you have to do is to make sure you know the meaning of each part. For example, you have to know what a whole number is. Basically, whole numbers are all the number from 0 to infinite (not decimal, not fractions), it doesn't include negative numbers.
Once you know what a whole is, then you can analyze the conjecture. Notice that the conjecture states that the difference of two whole numbers is a whole number, but if you subtract 2 - 5 you would get -3 which is an integer but not a whole number.
<h2>Therefore, the difference 2 - 5 can be a counterexample of the conjecture, proving that it's not true for all cases possible.</h2>
Answer:
(0.4291, 0.4743)
Step-by-step explanation:
Using the relation :
p ± Zcritical * Sqrt[(p(1-p)) / n]
P = x / n =. 1447 / 3203 = 0.4517
1 - p = 0.5483
Zcritical at 99% = 2.575
Sqrt[(p(1-p)) / n] = sqrt(0.4517(0.5483)) / 3203) = 0.008793
p ± Zcritical * 0.008793
Lower boundary = 0.4517 - (2.575 * 0.008793) = 0.4291
Upper boundary = 0.4517 + (2.575 * 0.008793) = 0.4743
(0.4291, 0.4743)
