Answer:

x-y

Step-by-step explanation:

First you must distribute:  

4(x-y)= 4x-4y

-3(x-y)=-3x+3y

4x-4y-3x+3y

Then combine like terms:

(be careful of negatives)

4x-<em>4y</em>-3x+<em>3y</em>

x-y

As people exited a movie theater, they were informally surveyed about whether they enjoyed the movie or not. Males Enjoyed: 47 D
Norma-Jean [14]

Answer:

(B) a = 41%, b = 3%

Step-by-step explanation:

The result from the survey is given below:

\left|\begin{array}{c|c|c|c}&Enjoy&$Did not Enjoy&$Total\\--&--&--&--\\Male&47&13&60\\Female&53&3&56\\Total&100&16&116\end{array}\right|

The second table is given as:

\left|\begin{array}{c|c|c|c}&Enjoy&$Did not Enjoy&$Total\\--&--&--&--\\Male&a&11\%&\\Female&46\%&b&\\Total&&&100\end{array}\right|

Now, from the first table

Total Number of Respondents =116

Therefore:

\dfrac{47}{116}*100 \approx 41\%\\\dfrac{13}{116}*100 \approx 11\%\\\dfrac{53}{116}*100 \approx 46\%\\\dfrac{3}{116}*100 \approx 3\%

Therefore:

a=41%

b=3%

The correct option is B.
