Does the line of best fit have to have a positive gradient?
Not at all. If the two variables have a negative correlation, that is as on increases the other decreases, then the line of best fit would have a negative gradient.
What is a layer in math?
A boundary layer in math is a region of very large values of the gradient of a certain function. It is also stated that a boundary layer has its origin in fluid dynamics.
Is anion is positive or negative?
negative. why is this question in math when it should be in chemistry?
How can you tell whether the sum of 71 and 43 is a positive or negative without actually finding the sum?
Well, honey, if you're adding a positive number with another positive number, the sum will be positive. So, in this case, 71 and 43 are both positive, so their sum will definitely be positive without needing to do the actual math. Math can be a real pain, but sometimes it's just that simple.
What is a positive difference in math terms?
When you subtract the smaller number from the larger number in the problem. The answer should always be positive.
In math what is the graident?
gradient in math refers to the slope of a line
What does a positive and a negative gradient look like?
A positive gradient goes uphill from left to right A negative gradient goes downhill from left to right
What is a positive gradient?
An uphill climb
When the coefficient of x is positive the line what?
Has a positive gradient (in a y=mx+c graph)
How want to know that the gradient of a curve in displacement-time graph is increasing or decreasing?
If the gradient is a positive number the curve is increasing, and if the gradient is a negative number it is decreasing.
How can you tell whether the gradient of a curve is increasing or decreasing?
Differentiate the curve twice and then enter a value for x. If the answer is positive, the gradient is increasing at that point. If the answer is negative, the gradient is decreasing at that point. And if the answer is zero, the gradient is not changing.
Does the line of best fit always have a positive gradient?
dunnno dunnno
What is a positive linear relationship?
A linear relationship is one where your equation forms a straight line. A positive linear relationship is one where this line has a positive gradient.
Will the gradient of y equals -x plus 1 be positive or negative?
negative
What is significance of correlation?
it shows any pattern that may emerge in any given set of date, this includes a positive or negative correlation. positive where a gradient goes from low to high negative where a gradient goes from high to low
What is your positive and negative?
positive is to add and negative is to subtract in math
What powers the proton gradient of positive ions in the stroma?
The proton gradient across the thylakoid membrane is powered by the flow of electrons from water to NADP+ during photosynthesis. This flow of electrons creates a proton gradient that drives ATP production through ATP synthase.
