First you do 2 x 3x which will be 6x you then look to see whether there is a plus or minus next we see that it is a minus after this you do 2 x 5 which is 10 so the first bit is 6x - 10 we then look to see whether we have a plus or a minis we look to see that it is a plus you then work out the next bracket so you do 3 x 2x to give us 6x we see that we need to add a plus then do 3 x 3 which is 9 together it is 6x - 10 + 6x + 9 so now we have to simplify it so you do 6x + 6x which is 12x then do -10 + 9 which is -1 so the answer is 12x - 1

What is the nth term of the geometric sequence that has a common ratio of 6 and 24 as it’s third term?

Llana [10]

$\bf \begin{array}{ccll}
n&term&value\\
\text{\textemdash\textemdash\textemdash}&\text{\textemdash\textemdash\textemdash}&\text{\textemdash\textemdash\textemdash}\\
1&a_1&a_1\\
2&a_2&6a_1\\
3&a_3&6(6a_1)\\
&&36a_1
\end{array}\implies \stackrel{\textit{3rd term is 24}}{36a_1=24}
\\\\\\
a_1=\cfrac{24}{36}\implies a_1=\cfrac{2}{3}$

$\bf n^{th}\textit{ term of a geometric sequence}
\\\\
a_n=a_1\cdot r^{n-1}\qquad 
\begin{cases}
n=n^{th}\ term\\
a_1=\textit{first term's value}\\
r=\textit{common ratio}\\
----------\\
r=6\\
a_1=\frac{2}{3}
\end{cases}
\\\\\\
\boxed{a_n=\cfrac{2}{3}\cdot 6^{n-1}}$

A sample is a subset of all possible data values for a given subject under consideration.

Tom [10]

Answer: True

Step-by-step explanation:

A subset is a term used in the sets topic In mathematics to describe a Part of A larger values being considered.

Sample In experimental procedures is known as Part of what is to be used to determine the reaction of a larger mass of specimen.

Taking these two definitions by side, it is quite evident that both of them represent taking part of a larger picture to form a smaller picture which does not totally deviate from the larger picture being considered.
