Answer:

$MSE = 10$

Step-by-step explanation:

Given

$SSTR = 200$

$SST = 800$

Required

Determine MSE

This is calculated as:

$MSE = \frac{1}{ddf} * SSE$

Where:

$SSE = SST - SSTR$

$ddf \to$ denominator df

So, we have:

$SSE = 800 - 200$

$SSE = 600$

To calculate the df, we have:

$r = 13$ --- observations

$n = 5$ treatments

So:

$ddf = Total\ df - Numerator\ df$

$Total = n*r-1 = 5*13 -1 = 64$

$Numerator =n - 1 = 5 - 1 =4$

$ddf =64-4=60$

So, we have:

$MSE = \frac{1}{ddf} * SSE$

$MSE = \frac{1}{60} * 600$

$MSE = 10$

A circle has a circumference of 138.16 meters. What is the diameter of the circle ?

Neporo4naja [7]

circumference = 2 π r
138.16 = 2 π r
138.16/2π = 2π/2π r
21.98884694 =r
Diameter = r X 2
Diameter = 21.98884694 X 2
Diameter = 43.97769388

Hello can someone try and help me

lyudmila [28]

Answer:

f(x)=-4x+/4

let y=f(x)

y=-4x+4

interchange the role of x & y

x=-4y+4

x-4=-4y

(x-4)/-4=y

y=-(x-4)/4

f-¹(x)=-(x-4)/4

yeah you are right
