In a regression analysis if the mean value of y is related negatively of the value of x then larger values of x is associated with?
If the value (not mean value) of y is related negatively to the value of x then larger values of x are associated with smaller values of y.
The larger of two supplements exceeds 7 times the smaller by 4 degrees. Find the measure of the larger angle?
The two angles are 158o and 22o Two supplementary angles add up to 180o Let the smaller angle be x and the larger y, then: y = 7x + 4o x + y = 180o → x + (7x + 4o) = 180o → 8x = 176o → x = 22o ← y = 7 x 22o + 4o = 158o
What happens to the graph of a line when the slope is negative?
Looking from left to right, or as the x values get larger, the y values are decreasing. On a graph the line would be tilted down if you follow from left to right.
What happens to the x and y coordinates when a figure is translated up?
Translated means "slide." The y coordinates are increased
What is y x -y?
(y * x) - y = y * (x - 1)
What is are IF statements?
IF statements provide a way to branch from one part of the program to another, when a certain condition is met. For example, IF (X>Y) THEN A=X-Y ELSE A=Y-X gives the same result as A=|X-Y| (absolute value). The program performs the X-Y calculation if X is larger than Y, and it branches to the Y-X calculation if Y is larger than X (or if they are equal).
What happens when the line y x is changed to y x 2?
If you mean: y = x and y = x+2 then the lines are then parallel to each
If the sum of two numbers is 3 times their difference and the larger number is 6 more than the smaller number what is the larger number?
12 Let x represent the smaller number and y the larger number. From the problem, we have two equations: x+y=3(y-x) y=x+6 Now solve for x: x+(x+6)=3((x+6)-x) 2x+6=18 x=12 Now use this to solve for y: y=x+6=6+6=12
In a regression analysis if the mean value of y is related negatively of the value of x then larger values of x is associated with?
If the value (not mean value) of y is related negatively to the value of x then larger values of x are associated with smaller values of y.
When do you say two quantites to be in the golden ratio?
Two quantities are said to be in the Golden Ratio if the ratio of the larger to the smaller is the same as the ratio of their sum to the larger. Algebraically, if X and Y are the two quantities and X<Y, then Y/X = (X+Y)/Y This gives the ratio as 0.5*[1 + sqrt(5)] = 1.61803...
When you add two numbers together the answer is 63 when you subtract the smaller number from the larger the answer is 15 what are the two numbers?
78
When a point lies on the x-axis what happens to the y-axis?
y = 0
The larger of two supplements exceeds 7 times the smaller by 4 degrees. Find the measure of the larger angle?
The two angles are 158o and 22o Two supplementary angles add up to 180o Let the smaller angle be x and the larger y, then: y = 7x + 4o x + y = 180o → x + (7x + 4o) = 180o → 8x = 176o → x = 22o ← y = 7 x 22o + 4o = 158o
What is the maximum value of -3x plus 4y?
-3x+4y doesn't have a maximum value because you can plug in anything for x and anything for y. In fact, if you keep x=0 and you plug in larger and larger numbers for y, you get a larger and larger output--it's unbounded.
What is the y intercept of this equation y-2x equals 5?
The y-intercept happens when x = 0, so if y = 2x - 5, then the y-intercept happens when y = 0 - 5, or -5.
Why is the graph of an inverse of a function flipped over the line y x instead of another line?
Because the inverse of a function is what happens when you replace x with y and y with x.
What happens to the graph of y equals x when the equation changes to y equals x 9?
The line y = x will shift up when you add a value to x and shift down when you subtract a value from x.
