How can you recognize and interpret associations in two-way tables?
galina1969 [7]

Answer:

Sometimes the best way to tell whether two variables are associated is to ask yourself whether they are not associated. Think backward. In a two-way frequency table, if the relative frequencies for one variable are the same (or close) for all categories of another variable, there is no (or little) associa

What is the end behavior to y=1^x?
hichkok12 [17]

Answer:

It graphs as a line: y will always equal 1.

Step-by-step explanation:

f(x) = 1^x will always equal 1

example:

f(2) = 1^2 = 1 * 1 = 1

f(3) = 1^3 = 1 * 1 * 1 = 1

...

f(100) = 1^100 = 1

No matter how many times you re-multiply, 1 times 1 will always equal 1.

Factor. ​9x^2+42xy+49y^2​ <br> Enter your answer in the box
Sonbull [250]

\qquad \qquad\huge \underline{\boxed{\sf ᴀɴsweʀ}}

The factorized form of the given equation is ~

\boxed{ \sf(3x + 7y) {}^{2} }

Let's solve ~

\qquad \sf  \dashrightarrow \: 9 {x}^{2}  + 42xy + 49 {y}^{2}

\qquad \sf  \dashrightarrow \: (3x) {}^{2}  + 2(3x  \times 7y) + (7y) {}^{2}

Now, as we can see, an Identity is applied here ~

that is ;

\qquad \sf  \dashrightarrow \:  {a}^{2} + 2ab +  {b }^{2}   = (a + b) {}^{2}

So, let's use this identity in our next step, taking :

  • a = 3x

  • b = 7y

\qquad \sf  \dashrightarrow \: (3x + 7y) {}^{2}
