Answer/Step-by-step explanation:

A positive number divided by a negative number equals a negative number.

a ÷ -a = -a

a x -a = -a

a + -a = -a

a - -a = +a

In a completely randomized experimental design involving five treatments, 13 observations were recorded for each of the five tre

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:

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

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

$MSE = 10$

The angle of elevation to the top of the Empire State Building in New York is found to be 11 degrees from the ground at a distan

Svetllana [295]

Draw a picture of a building and a one mile (or 5280 feet) distance to a point from the base of the building.

The angle of elevation is given as 11° and we want the height of the building or x.

tan(11°) = x/5280

5280 tan(11°) = x

1026.3 feet = x

I hope my answer has come to your help. Thank you for posting your question here in Brainly.

M×10+m×13=138<br><br>sorry theres another loll I'm so bad at these

Dimas [21]

So first of all you would add the two together
so it would be m23.

138÷23 would equal 6,

therefore m would equal six

to check it substitute m for 6 and you should get 138!
