To determine the degree of the product of the given trinomials, you would multiply the term with the highest degree of each trinomial together. Both trinomials are degree 2, and when you multiply x2<span> by </span>x2<span>, you add the exponents to get </span>x4<span>. Thus, the degree of the product is 4. If the product is degree 4, and there is only one variable, the maximum number of terms is 5. There can be an </span>x4<span> term, an </span>x3<span> term, an </span> x2<span> term, an </span>x<span> term, and a constant term. </span>

Using the normal distribution, it is found that the third quartile is of Q3 = 0.67, hence option B is correct.
In a normal distribution with mean
and standard deviation
, the z-score of a measure X is given by:
- It measures how many standard deviations the measure is from the mean.
- After finding the z-score, we look at the z-score table and find the p-value associated with this z-score, which is the percentile of X.
In this problem:
- The mean is of 0ºC, hence
.
- The standard deviation is of 1ºC, hence
.
The third quartile is X when Z has a p-value of 0.75, as
, hence <u>X when Z = 0.67.</u>
![Z = \frac{X - \mu}{\sigma}](https://tex.z-dn.net/?f=Z%20%3D%20%5Cfrac%7BX%20-%20%5Cmu%7D%7B%5Csigma%7D)
![0.67 = \frac{X - 0}{1}](https://tex.z-dn.net/?f=0.67%20%3D%20%5Cfrac%7BX%20-%200%7D%7B1%7D)
![X = 0.67](https://tex.z-dn.net/?f=X%20%3D%200.67)

I am pretty sure that D is a vertical angle because we know that a circle is 360 degrees, and using this we can assume that the opposite angle of D is the same degrees as D.
