1) The average increase in the level of CO2 emissions per year from years 2 to 4 is:
Average=[f(4)-f(2)]/(4-2)=(29,172.15-26,460)/2=2,712.15/2=1,356.075 metric tons. The first is false.

2) The average increase in the level of CO2 emissions per year from years 6 to 8 is:
Average=[f(8)-f(6)]/(8-6)=(35,458.93-32,162.29)/2=3,296.64/2=1,648.32 metric tons. The second is false.

3) The average increase in the level of CO2 emissions per year from years 4 to 6 is:
Average=[f(6)-f(4)]/(6-4)=(32,162.29-29,172.15)/2=2,990.14/2=1,495.07 metric tons. The third is false.

4) The average increase in the level of CO2 emissions per year from years 8 to 10 is:
Average=[f(10)-f(8)]/(10-8)=(39,093.47-35,458.93)/2=3,634.54/2=1,817.27 metric tons. The fourth is true.

Answer: Fourth option: The average increase in the level of CO2 emissions per year from years 8 to 10 is 1,817.27 metric tons.

NeX [460]
The equation for the line of best fit can be obtained as follows, using the least square method (for more info visit http://hotmath.com/hotmath_help/topics/line-of-best-fit.html ):

mean of X = 1/6
mean of Y = 2/3

slope, m = 704/1121 = 0.6

Computing the y-intercept using the formula:

b = mean of Y - m (mean of X) = 2/3 - (704/1121)(1/6)
b = 0.562 = 0.6

Therefore, the equation of the line of best fit, given the standard relation:

y = mx + b

y = 0.6x + 0.6

Which of the following is an example of a rational number that is not an integer? a. -3 b. 1 c. 1/3 d. 3
JulijaS [17]

Answer:

the answer is C.1/3

Step-by-step explanation:

Here is why  in mathematics, a rational number is a number that can be expressed as the quotient or fraction p/q of two integers, a numerator p and a non-zero denominator q. Since q may be equal to 1, every integer is a rational number.  Hope this helps. :)

Jimmy drove to his cabin on the lake and back. it took 0.6 hours longer to go there than it did to come back. the average speed
Neporo4naja [7]
To answer this item, we let x be the distance that Jimmy drove from his origin and back. Given the speeds, the time it takes for him to travel to and fro are,
                                   t1 = x / 46
                                   t2 = x / 52
respectively.

The equation that would best represent the scenario is,
                              x/46 - x/52 = 0.6
The value of x from the equation is 239.2.

The trip there takes x/46 which is equal to 239.2/46 which is also equal to 5.2 hours. The travel from the cabin back took 4.6 hours.
