The inverse of the statement is 'If it is Wednesday, then it is not sunny'
<h3>What is the inverse of a word?</h3>
The inverse of a word is simply the contrary nature or quality and could be termed opposite or reverse of a proposition or theorem that is formed by'
- contradicting both the subject and predicate
- Contradicting both the hypothesis and conclusion of a given proposition or theorem
For instance, the inverse of "if A then B" is "if not-A then not-B" and 'if not A, then B" is 'If A, not B ' is termed a compare contrapositive
From the information given, we have;
'If it is not Wednesday, then it is sunny'
We can see that the inverse of the proposition is;
'If it is Wednesday, then it is not sunny'
Thus, the inverse of the statement is 'If it is Wednesday, then it is not sunny'

The result of the given expression on simplification is -3
<h3>Solving expressions</h3>
Polynomials are expressions that has a leading degree of 3. Given the expression below;
x^2-x^3+x^2/-x^2
Simplify the numerator to have:
2x^2-x^2/-x^2
Factor out x^2 from the numerator
-x^2(2+ 1)/-x^2
-3x^2/-x^2
Cancel out x^2 to have;
-3x^2/-x^2 = -3
Hence the result of the given expression on simplification is -3

The given values are:
p = 22% = 0.22
Zc = 1.645 at 90% confidence level.
margin of error, E = 0.04
The formula we can use here is:
E = sqrt(pq/n) * Zc
0.04 = sqrt(0.22*(1-0.22)/n)*1.645
n = (0.22*(1-0.22))*(1.645/0.04)^2
n = 290.22
hence minimum sample size = 290
Ok first take out the GCF which is 3 in this case.
