What in math what does it mean when I'd a sample process is in control or not?

1 answer:

I'm not totally sure what you are asking, but maybe this is a question about dependent and independent variables?

If so, these types of variables are used in math and science as measures. In math, independent variables and dependent variables are the "tools" used in an experiment.

Independent variables are the variables that are controlled during the experiment. These variables do not change during the experiment.

Dependent variables are the variables whose values change based on the independent variables. These variables are the "outcome" portion.

I have no idea if this answers your question or not. All I can say is that the "controlled" part of a sample would be the independent variable.

AURORKA [14]

Answer:

Step-by-step explanation:

x - 3y = 4

x - 3(-3) = 4

x + 9 = 4

x = -5

(-5, -3)

-11 - 3y = 4

- 3y = 15

y = -5

(-11, -5)

I don't see how (0, -3) could be a solution to the equation.

$\qquad\qquad\huge\underline{{\sf Answer}}$

$\textbf{Since it's a right angled Triangle we can } \\ \textbf{ use Pythagoras theorem }$

$\sf{Cos (29°) = \dfrac{b}{c}}$

$\sf{Cos (29°) = \dfrac{b}{260}}$

$\sf{b= 260\cdot Cos (29°) }$

$\sf{b= 260\cdot 0.875 }$

[ $\textsf{Cos(29°)= 0.875}$ ]

$\sf{b= 227.5 in }$

A contractor records all of the bedroom areas, in square feet, of a five-bedroom house as: 100, 100, 120, 120, 180 What is the v

kifflom [539]

The variance is the total of the squared distances of the given data from the mean.

This can be calculated through the equation,

  σ² = summation of X² / N - μ²

where σ² is the variance X's are the data, N is the number of terms, and μ is the mean.

summation of X² = 100² + 100² + 120² + 120² + 180² = 81200
N = 5
  μ = (100 + 100 + 120 + 120 + 180) / 5
μ = 124

Substituting these values to the equation for variance,

  σ² = (81200/5) - 124² = 864

Thus, the variance is equal to 864.
