Polynomials are linear combinations of positive integer powers. For example,
is a polynomial, but
is not.
(In case you're unfamiliar with the term, a linear combination of two quantities is the sum of scaled versions of those quantities, e.g. a general linear combination of 
and 
is 
, where 
are any numbers.)
is not a polynomial; the offending term is 
, or 
.
Im not sure ask ur teacher
Hello from MrBillDoesMath
Answer: SAS, the second choice
Discussion:
The sides with a single "tick mark" in each triangle have the same length.
The sides with two "tick marks" in each triangle have the same length.
Finally the angle shown in each triangle is the same.
Hence we have congruence by S(ide)-A(ngle)-S(ide) which is the second bullet point from the top of the list.
Thank you,
Mr. B
If you search the internet you can find the answer I hope you can find the answer
Solution :
Let 
and 
represents the proportions of the seeds which germinate among the seeds planted in the soil containing 
and 
mushroom compost by weight respectively.
To test the null hypothesis 
against the alternate hypothesis 
.
Let 
denotes the respective sample proportions and the 
represents the sample size respectively.
The test statistic can be written as :
which under 
follows the standard normal distribution.
We reject at 
level of significance, if the P-value 
or if 
Now, the value of the test statistics = -1.368928
The critical value = 
P-value = 
= 0.171335
Since the p-value > 0.05 and 
, so we fail to reject at level of significance.
Hence we conclude that the two population proportion are not significantly different.
Conclusion :
There is not sufficient evidence to conclude that the 
of the seeds that 
with the percent of the 
in the soil.
