What is the product of the numerator of one ratio and the denominator of the other ratio called in a proportion?
The numerator of the second ratio and the denominator of the first ratio are called the means, and the numerator of the first ratio and the denominator of the second ratio are called the extremes. The product of the means equals the product of the extremes.
What is variable ratio and variable interval?
different between variable intervals and fixed ratio
What are 2 ratios that are equal called?
equivalent ratio
If two cylinders are similar and the ratio between the altitude lengths is 2 3 what is the ratio of their volumes?
8 27
The two solids are similar and the ratio between the lengths of their edges is 2 7 What is the ratio of their surface areas?
If the length ratio is 2:7 then the area ratio would be 4:49, squaring the 2 and the 7.
What is nonvertical line is the ratio of the vertical change to the horizontal change between any two points on a line?
The slope.
What is the ratio of the vertical change (rise) to the horizontal chnage (run) of a nonvertical line?
It is called the slope of a line.
What nonvertical line is the ratio of the vertical change to the horizontal changebetween any two points on the line?
note: that one and two on the y's ans x's and doesnt mean to the 2nd or 1st powery2-y1_______ x2-x1
Why does the ratio of rise and run in a linear function always the same?
The ratio of rise and run in a linear function (which its graph is a nonvertical line) is called the slope of the line. We can calculate the slope of the line by using any two points on the line and always the ratio of changes on their y-coordinates and the changes on x-coordinates (rise and run) is constant (unchanged). The reason is that two points determine a line and its direction, so the line is fixed and extends without end in that direction. Any line intersects the x-axis only at one point (we call it the x-intercept point) by forming an angle α (the inclination angle), where 0˚ ≤ α < 180˚, that is measured from the positive x-axis to the line. There is a theorem that state that the slope of a nonvertical line is the tangent of its inclination: m = tan α if α ≠ 90˚ (if α = 90˚, then the line is vertical and has no slope).
The ratio between the distance between two points found on the map as compared to the actual distance between these points in the real world?
look at the scale of the map
Can there be a ratio between decimal points?
Yes, it is possible. For instance there could be a gear ratio of 3.1:1 or you can have a waist-hip ratio of 0.8:1.
The ratio of current assets to current liabilities is called the?
The ratio between current assets to current liability is called "Current Ratio".
How is magnification calculate?
It can be measured as the ratio between two points in the image compared to the same two points in the pre-image.
When graphing the points can your tell whether or not they are collinear?
Yes. Calculate the ratio of the difference in y-coordinates and the difference in x-coordinates between pairs of points. If the ratio is the same, the points are collinear. If not, they are not. The only exception is if all the x-coordinates are he same and the ratio is not defined. In this case the points are also collinear - all on a vertical line.
What is called the Ratio between oxygen uptake and oxygen usage?
The ratio between oxygen uptake and oxygen usage is called the respiratory exchange ratio (RER). It is a measure of the ratio of carbon dioxide produced to oxygen consumed during metabolism. This ratio can vary depending on the type of fuel being used by the body for energy.
What are the defining characteristics of the Ratio Level of Measurement?
Equal intervals between points of that scale and a true zero
A ratio that describes the tilt of a line?
The slope of the line is the tilt of the line. The ration is the difference of two y points over the difference between two x points.
