Answer:
The Standard Deviation
Step-by-step explanation:
Your concentration should be on what the standard deviation tells us about the data. The standard deviation is a number which measures how far the data are spread from the mean. Let a calculator or computer do the arithmetic. The standard deviation, s or σ , is either zero or larger than zero.

Answer:
The single decimal multiplier is
.
Step-by-step explanation:
The single decimal multiplier is obtained by multiplying the following two numbers in decimal form:
![x = (1 + 0.14)\cdot (1 - 0.01)](https://tex.z-dn.net/?f=x%20%3D%20%281%20%2B%200.14%29%5Ccdot%20%281%20-%200.01%29)
Then, the number is:
![x = 1.129](https://tex.z-dn.net/?f=x%20%3D%201.129)
Answer:
Siti's money = RM 430
David = RM 1,290
Farid = RM 280
Step-by-step explanation:
Let
Siti's money = x
David = 3x
Farid = x - 150
Total of their money = RM 2 000
x + 3x + (x - 150) = 2000
4x + x - 150 = 2000
5x = 2000 + 150
5x = 2,150
x = 2,150/5
x = RM 430
Siti's money = x
= RM 430
David = 3x
= 3(430)
= RM 1,290
Farid = x - 150
= 430 - 150
= RM 280
This is a right triangle, the measure of angle A is 90 degrees.
First thing to do I guess is finding B and C.
tan^-1 (7/12) = 30 degrees
tan^-1 (12/7) = 60 degrees
60 + 30 = 90
180 - 90 = 90. Therefore angle A = 90 degrees
