Answer:
The calculation of a standard deviation involves taking the positive square root of a nonnegative number. As a result, both standard deviations in the formula for the slope must be nonnegative. ... Therefore the sign of the correlation coefficient will be the same as the sign of the slope of the regression line.

Answer:
Photosynthesis is the process by which plants use sunlight, water, and carbon dioxide to create oxygen and energy in the form of sugar
Explanation:
On a chilly, humid evening, intermolecular forces enable fog to form. The gaseous water molecules condense as a result of powerful molecular interactions.
What force allows fog formation?
From the south, warm, moist air is brought in, and if there is snow or cool precipitation on the ground, it will come into touch with the warm, moist breezes. The air coming in will cool as a result of this air-ground contact. Dew point rises at that position, leading to high humidity and the formation of fog.
What is molecular interactions?
Interactions between molecules or between atoms without bonds are referred to as molecular interactions. There are three types of molecular interactions: cohesive (attraction between like), adhesive (attraction between unlike), and repulsive forces.

Answer is: more ionic.
When the electronegativity difference is greater than 2.0, the bond is considered ionic.
Electronegativity (χ) is a property that describes the tendency of an atom to attract a shared pair of electrons.
Atoms with higher electronegativity attracts more electrons towards it, electrons are closer to that atom.
For example fluorine has electronegativity approximately χ = 4 and sodium χ = 1, fluorine attracts electron and it has negative charge and sodium has positive charge.
