The dot plot shows the lengths of the 12 trailers sold at a store last month. Which statement about the data is true? A. The interquartile range is 7, and the range is 17. B. The interquartile range is 7, and the range is 11. C. The interquartile range is 2.75, and the range is 17. D. The interquartile range is 2.75, and the range is 11.

the equation for this situation is y=122+45. to solve the equation you would add 45 and 122 to get a total of 167lbs. in conclusion, grace's weight eight weeks ago was 167lbs.  

the answer is b

step-by-step explanation:

to determine whether a given function is even, we simply substitute x with -x in the expression. if the result after simplification is identical to the original equation, then the function is said to be even other wise odd.

f(-x) = (-x)^2 - (-x) + 8

      = x^2 + x +8

the resulting function is not identical to the original one;

f(-x) ≠ f(x)

therefore, f(x) is not an even function
