Y=4x+rx+6 solve for x

Irina-Kira [14]

$y=4x+rx+6$

$y-6=4x+rx

$ $Subtract \ 6 \ from \ both \ sides$

$y-6=x(4+r)

 
$ $Factor \ out \ the \ common \ term \ x$

$\dfrac{y-6}{4+r} =x$ $Divide \ both \ sides \ by \ 4+r$

The value of t∗ for a 95% confidence interval when there are 10 pieces of data is:

Anarel [89]

Answer:

The t-critical value for 95% confidence interval is ±2.2621

Step-by-step explanation:

We are given the following information in the question:

Sample size, n = 10

Alpha, α = 0.05

We have to find the value of t-critical at 95% confidence interval.

Degree of freedom = n - 1 = 9

$t_{critical}\text{ at degree of freedom 9 and}~\alpha_{0.05} = \pm 2.2621$

The t-critical value for 95% confidence interval is ±2.2621
