Food color mixes faster in warm water than in cold water. Molecules in a liquid have enough energy to move around and pass each

other. This is why water can flow and take the shape of the container you pour it into. Warm water has more heat energy than cold water, which makes the molecules in warm water move faster than molecules in cold water. The food coloring you add to the water is pushed around by the water molecules. Since the molecules in warm water move around faster, the food coloring spreads out quicker in the warm water than in the cold water.

Isabella reads an article in the school newspaper quoting a study that reported a correlation coefficient of +0.85 for the relat
LuckyWell [14K]

Answer:

Strong positive

Explanation:

In studies, we usually establish relationships between two or more variables using correlations. Correlations tell us how this variables are related.

  • Two variables have a positive correlation when if one increases the other increases too.
  • Two variables have a negative correlation when if one increases the other decreases and vice versa.

Also, a correlation can be weak, moderate or strong. Researchers agree that a correlation that is larger than 0.70 should be considered a strong correlation.

In this example Isabella reads about a study saying there's a correlation coefficient of +0.85 between hours spent studying and final exam grade. <u>The fact that the sign of this correlation is "+" tells us that it is positive</u> (the more hours spent studying, the better final exam grade). We can also see that <u>the coefficient is 0.85 which is greater than 0.70 and therefore we can consider this correlation as a strong one.</u>

Thus, Isabella would conclude that this is a strong positive relationship.

Aleks04 [339]

Answer:

The main purposes of the New Deal were relief, recovery, and reform. By relief, the president meant that he intended to aid people in need right now by providing employment, food lines, and welfare. The goal of the recovery was to restore the economy and put an end to the Great Depression.

The Additional Deal imposed new restrictions and protections on the financial industry, as well as measures to re-inflate the economy following a dramatic drop in prices. During Franklin D. Roosevelt's first term in office, the New Deal initiatives comprised both congressional legislation and presidential executive orders.
