Step-by-step explanation:
=(y-y1)=Y2-Y1/X2-X1(X-X1)
Answer:

Step-by-step explanation:
As the mean is 20.2 and the standard deviation is 2.4
The range within the first standard deviation is
(17.8,22.6)
This means that we can safely use the range of (18,22) as we cannot confirm whether the other values fall within the range.
Within this range there are

9514 1404 393
Answer:
- sin(Z) = 9/15 = 3/5
- cos(Z) = 12/15 = 4/5
Step-by-step explanation:
The hypotenuse is the longest side, XZ (15). It is opposite the right angle (Y).
The segments adjacent to Z are the ones with Z in their name: ZX and ZY. When we talk about the "side" or "leg" adjacent to Z, we are usually not interested in the hypotenuse ZX. We refer to that as the "hypotenuse." So, the side or leg "adjacent" to Z is ZY, of length 12.
The segment opposite to Z is the one that does not have Z in its name: XY.
sin(Z) = Opposite/Hypotenuse = XY/XZ = 9/15 = 3/5
cos(Z) = Adjacent/Hypotenuse = YZ/XZ = 12/15 = 4/5
Answer:
9x² + 5x
Step-by-step explanation:
4x² + 6x + 5x²-x
Combine like terms:-
4x² + 5x² = 9x²
6x - x = 5x
9x² + 5x
