I am big brain. if she wants to know if it is correct, repeating the exact ay would show her if it is right or if she did something wrong
The correlation coefficient is a number between zero and 1 and the answer is <u>false</u>
And that is because the correlation coefficient is a number between -1 and one. A positive correlation coefficient means that two variables are positively correlated or move in the same direction. Plus one means perfect like full correlation, zero means there is no correlation whatsoever.
And a negative correlation means that as one variable moves in a positive direction, the other moves in a negative direction, so that is negative correlation, And the correlation of -1 means perfect negative correlation.
<h3>What Is the Correlation Coefficient?</h3>
The correlation coefficient is a statistical measure of the strength of the relationship between the relative movements of two variables. The values range between -1.0 and 1.0. A calculated number greater than 1.0 or less than -1.0 means that there was an error in the correlation measurement.
A correlation of -1.0 shows a perfect negative correlation, while a correlation of 1.0 shows a perfect positive correlation. A correlation of 0.0 shows no linear relationship between the movement of the two variables.

Answer:
Mass of iron = 59.375 gm
Explanation:
Calories ( or joules) are added to the water by the hot steel so at the endpoint they are BOTH at 40 C
The water gains:
4.18 j/g-C * 50 * (40-30 C) = 2090 j
The steel gave up 2090 j going from 120 to 40 C
2090 = .44 j/g-C * m * (120-40) solve fro m = 59.375 gm
