40.5 hours

Step-by-step explanation:

Monday hours: 8 hr 30 min

7-11:30 is 30 min and 4 hr

12:15-4:15 is 4 hr

Tuesday hours: 7 hr and 45 min

7:00 to 12:30 is 30 min and 5 hr

1:45 - 4:00 is 15 min and 2 hr

Wednesday hours: 9 hr

7:30-12:15 is 45 min and 4hr

12:45-5:00 is 15 min and 4hr

Thursday hours: 9 hr

7:15-12:15 is 5 hr

1:30-5:30 is 4 hr

Friday hours: 6 hr and 15 min

8:45-12:15 is 30 min and 3 hr

1:15-4:00 is 45 min and 2 hr

18 + 1 + 13 + 8 + 30 min

40 hr and 30 min

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 answer to the question provided is 14.4 ft.

Step-by-step explanation:

We can solve this using proportion!

$\frac{18}{x} = \frac{10}{8} \\ \\ \frac{10x}{10} = \frac{144}{10} \\ \\ x = 14.4$

Please answer i need help quick

Answer:

(-2, 6)

Step-by-step explanation:

Since you want a 1 to 7 ratio, you want to divide the line into 2 parts, where one part has a length of 1 and the other has a length of 7. So the total length of the line is 8.

Start by looking at the difference in the X and Y coordinates.

X = | -4 - 12 | = | -16 | = 16

Y = | 7 - -1 | = | 8 | = 8

You could calculate the length of the line using pythagorian's theorem, but that's not needed. Simply use similar triangles. We have a right triangle with legs of length 16 and length 8. We want a similar triangle that is 1/8th as large (to get the desired 1 to 7 ratio). So divide both legs by 8, getting lengths of 16/8 = 2, and 8/8 = 1.

Now add those calculated offsets to point A.

A has an X coordinate of -4 and B has an X coordinate of 12 and the X coordinate for C must be between those limits. So calculate -4 + 2 = -2 to get the X coordinate for C.

The Y coordinate of A is 7 and the Y coordinate of B is -1. And since the Y coordinate must be between then, you have 7 - 1 = 6.

So the coordinates for C is (-2, 6)
