When x is a positive integer, if y = 3 - 5x, and 2z = 10x + 2, what is the sum of y and z? Prove that, for all positive integers 1 + 2 + \cdots + n = \frac{1}{2} n (n+1) . Negative plus a positive equals what?
If x equals a negative number, what is the additive inverse of the number -x? Explain. How do you add a positive number and a negative number? Give a numerical example when negative + negative = positive. If a negative number is multiplied by a positive number, is it possible to get ...

When the length of each side of the triangle is a positive integer, the three numbers make aPythagorean triple.(3,4,5)is the smallest triple with32+42=52. The Chinese textChou Pei Suan Ching– original titleZhoubi– (周髀算经), (The Arithmetical Classic of the Gnomon and the Circular ...
For now I’ll just memorize a negative * a negative = a positive. I’ll ask my school teacher daughter to explain it, says: Oh wow. You guys need to consider that numbers are directional vectors. The opposite of a vector is the negative (-) of that vector. Therefore -3 x -3 is...
In that case, higher q values indicate that decision-makers have a more negative attitude, while lower values indicate a more positive attitude. Therefore, different DM can select the most appropriate value of q based on their attitude.
(A–D) Differences in IPS among different risk groups in the four situations: negative immunoresponse to both PD-L1/PD-1 inhibitors and CTLA-4 inhibitors (A); positive immunoresponse to PD-L1/PD-1 inhibitors (B); positive immunoresponse to CTLA-4 inhibitors (C); positive immunoresponse ...
The lack of a decision is the same as a negative decision; no green light is a red light, and work can stop for a whole organization. Delegation without follow-through is abdication. Any decision be worked out and reached at the lowest competent level. The reason is that this is where ...
Which are the truly predicted positive class (TP) and truly predicted negative class (TN) to all the predictions, which are the true predictions of positive class (TP) and negative class (TN) and the falsely predicted positive class (FP) and the falsely predicted negative class (FN). As ...
for some positive value of r; r has an upper bound of − ∑ i = 1 n γ i log ( γ i ) . The variables α, γ, and ψ all have probabilistic interpretations: α j = p ( v φ j ) and γ i = p ( v π i ) correspond to marginal probabilities of states v φ j and ...
