When two negative numbers are multiplied, is the answer positive or negative? 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...
Find the square root of 6 + 6 i so that the real part of your answer is positive. What is the positive square root of What is the square root of a negative number? Is negative square root of 9 a rational number? What is the principle square root of negative 121? Is the...
Last time I checked, one negative multiplied by the same negative number (negative number squared) is a positive number. Why the discussions lasted so long was not because what I wrote was wrong, but the titles of the thread are misleading. What the arguments are is about order of operation...
To ensure that this plot is not biased for any specific uncertainty measure, participants were classified as risk averse/seeking if they had a significant negative/positive Unc[r] effect according to any of the three models (SD, range or entropy; Supplementary Table 2). Also, to illustrate ...
The greater this value, the more significant the variable is. The difference is expected to be positive, but if it is a negative number, then it implies that the random permutation worked better inferring that the feature does not have a role in the prediction and is not deemed important. ...
This correlation can range from -1 to 1, and so the square of the correlation then ranges from 0 to 1. The greater the magnitude of the correlation between the predicted values and the actual values, the greater the R-squared, regardless of whether the correlation is positive or negative....
Easier if the value of a is 1. To find the values to go with the brackets you need 2 values that when added give you b and when multiplied together give you c. If c is positive and b is negative then the values that go with the brackets will be negative. If a is not equal to...
The average rate of change of an increasing function is positive, and the average rate of change of a decreasing function is negative. Figure 3 shows examples of increasing and decreasing intervals on a function.Figure 3. The function f(x)=x3−12xf(x)=x3−...
Fit a GPR model using the squared exponential kernel function with a separate length scale for each predictor. This covariance function is defined as: k(xi,xj∣θ)=σ2fexp[−12d∑m=1(xim−xjm)2σ2m]. where σm represents the length scale for predictor m, m = 1, 2, ..., d...
Why is the square root of all the real numbers not a function? Why/how does the exponent of 1/2 mean the square root? Explain. Why can't the square root of a^2 + b^2 be simplified? Why do negative numbers in parentheses squared become positive?
