Well I figured it out and I came up with 13 square inches. you can find this out by doing the square root of 169. I hope this help :).
Answer: 1:2
Step-by-step explanation:
Well, if you're asking for the ratio, it is 1:2
For every 1 notebook bought, there would be 2 free pens.
Since she bought 8 notebooks, just multiply 2 by 8 which will result in 16.
Answer:
16+2.36 is 18.36 i dont know if this was suppose to be the answer to the question but that what thhat equal
Answer:
The percentage of the variability in plant weight is NOT explained by height is
%
Step-by-step explanation:
From the question we are told that
The correlation between height and weight is 
Generally the R-Squared between height and weight is mathematically represented as
substituting values
This R-Squared tells us the percentage of plant weight is accounted by height
and from the calculation we see that it is 56.3%
Now the percentage of plant weight that is not accounted by height is
%
The scale factor is -2. The answer is choice A

How did I get this answer? By picking any pair of preimage and corresponding image points. Let's pick on preimage point A and its paired image value A'.
Note how the x coordinate jumps from -11 to +22. So we multiplied by -2 to do this jump. We can see that 22/(-11) = -2 is another way to get this. Similarly, the same happens to the y coordinates as well: -14/7 = -2.
In short, you multiply the preimage coordinate by the scale factor -2 to get the corresponding image coordinates. Points B and C will follow the same pattern.
