<em><u>Polynomials in standard form:</u></em>

<em><u>Solution:</u></em>
Standard form of polynomials: terms are ordered from biggest exponent to lowest exponent
<em><u>Option A:</u></em>

The above is a polynomial
Where, largest exponent is arranged first
Therefore, it is standard form of polynomial
<em><u>Option B</u></em>

Here, exponents are from greatest to least
Therefore, it is standard form of polynomial
<em><u>Option C</u></em>

Here, "t" is a variable. The first term has largest degree
Therefore, it is standard form of polynomial
Answer: add 22 with $18.55 divide 50%
Step-by-step explanation:
Considering the situation described, the null hypothesis is given as follows:
.
<h3>What are the hypothesis tested?</h3>
At the null hypothesis, it is tested if the <u>mean is the same as in the Census</u>, of $64,000, hence:
.
At the alternative hypothesis, it is tested if the mean is different from the Census, hence:
.

The area of a triangle is bh/2. If we know the height (8m), we can plug it into a=bh/2 for a=8h/2 or a=4h or a/4=h
Since we know the area (44m^2), we can put that in for 44/4=h or h=11 metres.
