The prevalence of a disease can directly influence screening characteristics of a diagnostic test, especially its sensitivity and specificity. Trying to eliminate this ef-fect, LR was developed. Pre-test probability of a disease multiplied by positive or negative LR can estimate post-test probability...
When you multiply X by a positive integer Y you’re adding it to itself Y times. So it makes sense that a positive times a positive is positive. For example, . By looking at 3 (or any other number you like) multiplied by smaller and smaller integers you see a pattern: Every time y...

Negative numbers, all numbers lower than zero written with a negative sign '-' (-3, -4, -5, etc), can be multiplied and divided much like positive numbers. Use the examples provided to master applying multiplication and division to negative numbers. ...
Water molecules have poles of positive and negative electric charge that are known to create attractive forces between cells, known as van der Waals forces. The particles that move are electrons, and they carry a negative charge. Electrons have a negative charge, and the two Polar Regions tend...

If a negative number is multiplied by a positive number, is it possible to get a positive number? If x is a positive integer and y is a negative integer, then x+y is ___ equal to 0. a. never b. sometimes c. always Is every integer a whole number? Can a negative number be a...
The negative exponent rule states that the base must be written as its reciprocal, and then the exponent will become positive. 10 to the negative power of 2 is rewritten as 1/10 to the power of 2. 10 to the power of 2 is 100, so 10 to the negative power of 2 is 1/100. ...
If two negative numbers are multiplied together or divided, the answer is positive. If a positive and a negative number are multiplied or divided, the answer is negative. Examples (-2) ÷ (-4) = ½ (8) ÷ (-2) = (-4) 2× (-3) = (-6) ...
