ikadub [295]2 years ago
6 0

Answer:

{10x}^{2}  - 18 {x}^{3}  +  {14x}^{4}  \\

factorise out x² :

=  {x}^{2} (10 - 18x + 14 {x}^{2} )

then factorise out 2:

= 2 {x}^{2} (7 {x}^{2}  - 9x + 5)

Annual starting salaries for college graduates with degrees in business administration are generally expected to be between and
kenny6666 [7]

The planning value for the population standard deviation is 4330.

Given the confidence interval 20000 and 35000.

We have to find the planning value of standard deviation.

Standard deviation is measuring dispersion of data. Uniform probability distribution has two bounds a and b. The standard deviation is given by :

s=\sqrt{(b-a)^{2}/12 }.

Annual starting salaries for college graduates be between 20000 and 35000.

It is uniform in the interval so, a=20000, b=35000.

Now we have to just put the values of a and b in the above formula to get the value of standard deviation.

s=\sqrt{(35000-20000)^{2} /12}

=\sqrt{(15000)^{2} /12}

=\sqrt{225000000/12}

=\sqrt{18750000}

=4330

Hence the planning values for the population standard deviation is 4330.

What's the difference between a independent variable and dependent variable
Travka [436]

Answer:

The dependent variable depends on the independent variable.

Step-by-step explanation:

  • The variable whose values are deliberately changed by the researcher in order to obtain the desired outcome is called independent variable...
  • The values of the independent variable can be changed as per requirement, by the researcher...
  • Manipulation can be done in the values of independent variable, but the researcher observes the value of a dependent variable during an experiment.
  • An independent variable is a presumed cause whereas dependent variable is a measured effect.
  • In a simple linear regression, ‘y’ denotes dependent variable while ‘x’ denotes independent variable, which means y depends on x
