And slowness of course. Enjoying a meal with friends or family is the main ingredient of any Italian dish. Italian Sunday lunches are the best example, a unique experience you should try at least once. They say only 5% of Italians eat out on Sundays, while 95% are at home eating as much as humanly possible. Sunday lunch is usually spent at some relativesâ home, in my case my grandparentsâ.
A minus one indicates a perfect negative correlation, while a plus one indicates a perfect positive correlation. A correlation of zero means there is no relationship between the two variables. When there is a negative correlation between two variables, as the value of one variable increases, the value of the other variable decreases, and vise versa. In other words, for a negative correlation, the variables work opposite each other.
Zero is an acceptable value for a variable. As a general rule, if you solve an equation and get x equals zero, that's just what it is: zero. There is one solution. Example: 10x +1 = 5x +1. 5x = 1 - 1. 5x = 0. x = 0. There is one solution, zero. If you solve for x and get two solutions, such as 2 and 0, there are two answers.
