What will be the correlation for the graph of this equation y equals 14x?
Since y=14x is a perfect linear relation, the correlation would be 1.
What are the variables for 2x - 5y plus 3z equals -1?
x, y and z are the variables.
What is a numerical factor of a multiplication expression?
Multiplicand times multiplier equals product. If the expression has a variable, the numerical factor of the variable is the coefficient.
What is the numerical factor in a variable term?
Multiplicand times multiplier equals product. If the expression includes a variable, the numeral is the coefficient.
What is y equals five minus one fourth x?
It is a linear equation in two variables
When there is no linear correlation the correlation coefficient equals?
0
What happens if the correlation coefficient equals 0?
Nothing happens. It simply means that there is no linear relationship between the two variables. It is possible that there is a non-linear relationship or that there is none.
How do you calculate friction equals coefficient of friction X normal force when frictional force and coefficient force are variables not given?
Friction= (coefficient of friction)(normal reaction) If you don't have the friction or the coefficient of it I'm sure you must have been given something else. Could you add the exact question to the discussion ?
For the data below compute the Pearson correlation X Y 1 2 2 3 4 2 5 6 8 7 x equals 20 y equals 20 equals 40?
No, the Pearson coefficient does not equal 40.
What is the slope b of the least squares regression line y equals a plus bx for these data?
The graph and accompanying table shown here display 12 observations of a pair of variables (x, y).The variables x and y are positively correlated, with a correlation coefficient of r = 0.97.What is the slope, b, of the least squares regression line, y = a + bx, for these data? Round your answer to the nearest hundredth.2.04 - 2.05
What is the coefficient in the number sentence 8x equals 16?
8 is the coefficient. A coefficient is the number in front of a variable.
How do you solve 5t-5 equals 5t plus 7?
You don't for t, as gathering your coefficient variables together = 0 5t - 5 = 5t + 7 now, subtracting 5t from either side to get the variables on one side of the equation renders this. - 5 does not = 7
What is the coefficient in Y equals 2X?
It is 2
In a correlation coefficient the difference between r and r squared?
r is correlation and can be positive or negative. If you want an analogy, consider it like the slope of a line. If the slope is negative, the line slopes downward and therelationship between the two variables (x & y) are inverse. That is, as x increases, y will decrease. If r is positive, then the line slopes upward and as x increases so does y. Now if x equals or is close to zero, there is no significant relationship between the two variables ... as x increases y does not change or fluctuates between positive and negative changes. The closer r is to +1 or -1, the stronger the relationship between x and y.
What is the coefficient in 4 plus x equals y?
The only coefficient here is just 1
What is the coefficient in front of iron Fe plus O2 equals Fe2O3?
The coefficient of Fe2O3 is 1
What is the coefficients of -3x2 equals -9?
The coefficient is -3.
