y = 12000x + 35000


When Mr. Nicolas began recording, it means, at 0 hour, how many tortillas was produced?


Subs x by 0.


y = 12000.0 + 35000

y = 0 + 35000

y = 35000


When Mr. Nicolas began recording the data, 35,000 tortillas had already been produced


The total number of tortillas produced 2 hours after the he began, it means, when x = 2


y = 12000 . 2 + 35000

y = 24000 + 35000

y = 59000


The total number of tortillas produced 2 hours after he began recording the data was 59,000


The total number of tortillas produced _ hours after he began recording the data was 85,000


Now we have y but not x.


y = 12,000x + 35,000

85,000 = 12,000x + 35,000

85,000 - 35,000 = 12,000x

50,000 = 12,000x

x = 50/12

x = 25/6

x = 4,1666...

Rounding

x = 4,167

If a data set has ssr = 400 and sse = 100, then the coefficient of determination is
BARSIC [14]
To solve this problem you must apply the proccedure shown below:

 1. You have that the <span>data set has SSR=400 and SSE=100

 2. Therefore you have </span><span>the coefficient of determination is:

 r</span>²=SSR/SSTO

 SSTO=SSR+SSE

 3. Then, when you substitute the values, you obtain:

 SSTO=400+100
 SSTO=500

 r²=400/500

 4. So, you have that the result is:

 r²=0.8

 Therefore, as you can see,  the answer for the exercise shown above is: <span> the coefficient of determination is 0.8</span>
