For the given sample, mean = 1.306 and standard deviation = 0.1826.
As given ,
Given sample
: 1.38, 1.18, 1.47, 1.35, 1.52, 1.23, 1.62, 1.17, 1.03, 1.11
Total samples N=10
Mean
= ( 1.38+1.18+ 1.47+ 1.35+ 1.52+ 1.23+ 1.62+ 1.17+ 1.03+1.11)/ 10
= (13.06 ) /10
= 1.306
= (1.38 -1.306)² + (1.18 -1.306)² +(1.47 -1.306)² +(1.35 -1.306)² +(1.52 -1.306)² +(1.23 -1.306)² +(1.62 -1.306)² +(1.17-1.306)² +(1.03 -1.306)² +(1.11 -1.306)²
=0.33344
Standard deviation =
= 
= 0.1826
Therefore, for the given sample, mean = 1.306 and standard deviation = 0.1826.

Answer:
(x + y)1 - a)
Step-by-step explanation:
x + y - ax - ay
= x - ax + y - ay
= x(1 - a) + y(1 - a)
= (x + y)1 - a)
Answer:
Angle b = 20
Angle c = 160
Step-by-step explanation:
You know this because angle b corresponds with the other 20 degree angle. A line equals 180 so therefore 180-20 = 160.

Answer: Quadratic; 6x^2, x, -12
Detailed Explanation:
The highest power of the function (degree) is 2. Therefore it is a quadratic function. The quadratic term is 6x^2 since its power is 2, the linear term is x since its power is 1 and the constant term is -12.
