Which of the following terms refers to the numerical probability of the chances that the true value falls within the range of reliability?mean
variability
confidence level
standard deviation

Answers

Answer 1

Answer: The term that refers to the numerical probability of the chances that the true value falls within the range of reliability is called confidence level.
Saving that you surveyed a whole population, a 100% confidence level is non-existent in statistics, — and even then you probably couldn’t be 100 percent sure that your survey wasn’t open to some kind of error or bias.

PLEASE HELP! DUE TOMORROWWrite each equation in standard form.

y - 4 = -3(x - 3)

and

y + 9= 2(x + 5)

Answers

I think you do not want to find the value of x and y from the two given equations. Only thing you want is to write the equations in their standard form only. Let us take one equation at a time and then write them in their standard form.
In case of the first equation:
y - 4 = - 3(x - 3)
y - 4 = - 3x + 9
3x + y = 9 + 4
3x + y = 13
Now we take the second equation
y + 9 = 2(x + 5)
y + 9 = 2x + 10
2x - y = 9 - 10
2x - y = -1
These are the two standard form of the given equations.

For the first equation...
$y-4 = -3x+9 \n 3x+y = 13$

For the second equation...
$y+9 = 2x+10 \n -2x+y = 1 \n 2x -y = -1$
