<h3>Answer:  Choice C)  -3m^12n^6</h3>

Explanation:

The coefficients -24 and 8 divide to -24/8 = -3. Based on this alone, the answer is between choices B and C.

The m terms divide to \frac{m^5}{m^{-7}} = m^{5-(-7)} = m^{5+7} = m^{12}

Notice how I subtracted the exponents. The general rule is \frac{a^b}{a^{c}} = a^{b-c}

Since we get m^12, this points us to choice C as the final answer

For the sake of completeness, here's what the n terms divide to

\frac{n^4}{n^{-2}} = n^{4-(-2)} = n^{4+2} = n^{6}

user100 [1]

Answer:

Part A: YES, it is.

Part B: the amount of pumpkin picked and the amount of fertilizer applied.

Step-by-step explanation:

Part A:

The closer the correlation coefficient is to 1, the stronger the relationship between two variables, and vice versa. Also, the closer the data points are on a scatter plot, the closer the correlation coefficient is to 1.

The scatter plot shown indicates a positive correlation between number of days and number of pumpkins. However, the data points are to some extent farther apart from each other. This shows a moderate relationship between the two variables. Therefore, a correlation coefficient, r, of 0.51 that was calculated can be concluded to be accurate , because an r of 0.51 depicts a moderate relationship between two variables.

Part B:

A variable that could affect the number of pumpkins picked could be amount of fertilizer applied, instead of the day in October. Thus, we can compare the amount of pumpkin picked and the amount of fertilizer applied.
