Answer:

26

Step-by-step explanation:

SST = ∑ ( y − ȳ ) ² (ȳ = pronounced y bar is the mean of y values)

ȳ = (4+6+11)/3 = 21/3 = 7

∑ ( y − ȳ ) ² =  ( 4 − 7 ) ² +  ( 6 − 7 ) ² +  ( 11 − 7 ) ²

=  (  − 3 ) ² +  (  - 1 ) ² +  ( 4 ) ²

= 9 + 1 + 16

= 26

Answer: 26

Step-by-step explanation:

First Data: (4 - 7)^2

Second data: (6 - 7)^2

Third Data: (11 - 7)^2

So the SST is (4 - 7)^2 + (6- 7)^2 + (11 - 7)^2 = 9 + 1 + 16 = 26

Hope this helps! :)

How to find the exterior angle
Vlad1618 [11]

X + 12 + X - 6 = X + 50

2X + 6 = X + 50

X = 44

44 + 50 = 94

To check you can substitute X into the problem.

44 + 12 = 56

44 - 6 = 38

44 + 50 = 94

56 + 38 = 94

94 = 94

When carbon is burned in air, it reacts with oxygen to form carbon dioxide. When 16.8g of carbon were burned in the presence of
dlinn [17]
The balanced chemical reaction is written as:

C + O2 = CO2

We are given the amounts of the reactants to be used in the reaction. We use these values for calculations. Since there is oxygen that is left in the reaction then the limiting reactant would be carbon. We calculate as follows:

16.8 g C ( 1 mol / 12.01 g) ( 1 mol CO2 / 1 mol C ) ( 44.01 g / 1 mol) = 61.56 g CO2 produced
