Find the t-value such that the area in the right tail is 0.005 with 28 degrees of freedom.
klasskru [66]

Answer:

t = 3.673900

Step-by-step explanation:

Given

df = 28 -- degree of freedom

Area = 0.005

Required

Determine the t-value

The given parameters can be illustrated as follows:

P(T > t) = \alpha

Where

\alpha = 0.005

So, we have:

P(T>t) = 0.005

To solve further, we make use of the attached the student's t distribution table.

From the attached table,

The t-value is given at the row with df = 28 and \alpha = 0.005 is 3.673900

Hence, t = 3.673900

8x+5y=24<br> y=−4x<br> ​what is X and Y??
Mrac [35]

Answer:

Step-by-step explanation:

plug y into the first equation:

8x+5y=24

8x+5(-4x)=24

8x-20x=24

-12x=24

x=-24/12

x=-2

then plug x to the second equation

y=-4

y=-4(-2)

y=8

x=-2

y=8
