sample
échantillon m

Sample. A finite percentage of a population (may be infinite). For example:
A sample from a set of integers could be 1,3,5,7,9,11 or 1,4,9,16,25 or .8-3-2-1-... etc.

And the sample from the alphabetic letters could be (vowels) or (consonants).

satisfaire

Fulfillment. 1 - Fulfilling existing conditions. For example: 120° satisfies
the requirements for the angle to be obtuse.
2 - A value or set of values ​​is said to satisfy an equation if it makes the equation balanced when substituted For example: 3 = x satisfies the equation 5 = 14 + x2 because 32 + 5 = 14 is true.

And 2 = x and 3 = y satisfy the equations 5 = y + x

And 1 = x2 - y because 5 = 2 + 3 and 1 = 3-2 2 are both true.

scalar
scalaire

Scalar. A scalar quantity has only magnitude and no direction (unlike a vector which has magnitude and direction). For example: time, distance, mass, and volume are all scalar quantities.

scale
échelle f

Scale gradation 1 - A series of marks on a ruler or measuring cylinder, etc., used as a measuring tool for distances, volumes, etc. See the drawing.

2 - Drawing an object to scale means that its measurements are in the same ratio as the original measurements. The map scale is 1:50,000 meaning that every 1 cm on the map represents 50,000 cm, or 0.5 km, on the ground.

scale factor
facteur m de l'échelle

Scale factor. When a shape is enlarged or reduced, the scale factor is determined as follows:

The distance between any two points on the image / the corresponding distance on the object

If the areas of the two shapes above are compared, the area of ​​the enlarged shape is equal to nine times the area of ​​the original shape. Here we say that the area scale factor is equal to 9.

If a solid, such as a cuboid measuring 4×2×3, is enlarged so that its size becomes 8×6×4, we notice that all linear measurements are doubled, all areas are multiplied by four, and all volumes are multiplied by eight.
Then we say that:

Linear scale factor = 2
Area scale factor = 4 (note that (22=4)). Volumetric scale factor 8 (note that (23=8)).

scalene
triangle m quelconque

Scalopic triangle. A triangle that has no equal sides or angles.

60°
50°
70°
A scaleopic triangle may be a right triangle

3 cm
4 cm
5 cm
