What is negative 3 squared? What is negative 5 squared? What are negative numbers? If 3 times a number minus 2 equals 13, what is the number? If x and y are both negative integers, then x+y is ___ equals to 0. a. never b. sometimes c. always What...
Because the variance is the product of squares, it is no longer in the original unit of measure. Since price is measured in dollars, a metric that uses dollars squared is not very easy to interpret. Therefore, the standard deviation is calculated by taking the square root of the variance, ...
The Pearson correlation coefficient is frequently referred to as r. This is because r is the value it takes when using statistical notation. This type of coefficient is standardized, which means it must fall within certain bounds. This is in contrast to a value, such as the...
Variance is a statistical measurement of the spread between numbers in a data set. It measures how far each number in the set is from themean(average), and thus from every other number in the set. Variance is often depicted by this symbol: σ2. It is used by both analysts and traders...

Square roots of negative numbers are undefined. There doesn’t exist any negative perfect square numbers. The area of the geometric shape “square” having side “s” is given by s×s=s2. The principal square root of a number is the positive square root. Usually, “the square root” of...

Pearson coefficients range from +1 to -1, with +1 representing a positive correlation, -1 representing a negative correlation, and 0 representing no relationship. The Pearson coefficient shows correlation, not causation. English mathematician and statistician Karl Pearson is credited for developing many...
Is (x^2 - a^2) the same as (x - a)^2? If so, would (x^2 - a^2)/(x - a) = (x - a)? Let A = x -2 y 6. Determine the values of x and y for which A^2 = A. What does 3 squared equal? If x + y = 12 and xy equals 50, what does x squared plus y sq...
