Answer:

0=0

Step-by-step explanation:

When you  combine both expressions  you multiply the first one  by -3

As result all the terms in the second expression are cancelled when both expressions are added

-3x -6y = -30

3x  + 6y =30

0   +  0  = 0

Solver for x- and y- 3x+y=12
Elan Coil [88]
Salutations!

First, add -2y to both sides.
-3x + 2y + -2y = 12 + -2y
-3x = -y + 12

Second, divide by -3 on both sides.

\frac{-3x}{-3} =   \frac{-2y + 12}{-3} 

x =  \frac{2}{3} y - 4

Hope This Helps!!!

The conditional relative frequency table was calculated by row using data from a survey of one station’s television programmin
Setler [38]

The conditional relative frequency presents the result of the survey that conveys information about the programming and the audience.

  • The best description of the value 0.357 in the table is; <u>Given that the program was targeted at adults, there is a 37.5% chance that it was recorded</u>.

Reasons:

The table is presented as follows;

\begin{tabular}{|c|c|c|c|}&Live&Recorded&Total\\Adult&0.625&0.375&1.0\\Children&0.5&0.5&1.0\\Total&\approx 0.583&\approx 0.417&1.0\end{array}\right]

Based on the given table, we have that the programs are categorized based on the intended audience.

Therefore, the 0.375, indicates that 37.5% of the program targeted at adults are recorded.

Therefore, the correct option is;

<u>Given that the program was targeted at adults, there is a 37.5% chance that it was recorded.</u>
