Use quadratic regression on your calculator.
See my graph below.
y=24.093915 + 0.02876392 x^2
Minimize sum of squared deviations
I did it by hand on Android spreadsheet
x y f(x) (y-f(x))^2
sum of squared devìation from the line 17.80312941
43.6 * 2.94 = 436/10 * 294/100 = (436 * 294)/1000 = 128184/1000 = 128.184
sorry im in6th grade i dont know but i dont get what the q is asking so im realy sorry
(Hope this explanation can ease your mind a little if possible! Alright let's go! :D)
Let n be the middle of the 3 consecutive even integers. Therefore, (n - 2) and (n + 2) are the smallest and largest of the 3 numbers respectively.
We know that (n - 2) + n + (n + 2) = 78,
so 3n = 78, and n = 78/3 = 26.
Since the middle number is 26, the smallest number is 26 - 2 = 24 and the largest number is 26 + 2 = 28.
Feel free to comment below if you have any queries!
The Pythagorean Theorem is l^2 + l^2 = H^2:
Substituting 12 and 16 as our l's we achieve:
12^2 + 16^2 = 144 + 256
144 + 256 = 400
Square root of 400 = 20
So H or Hypotenuse = 20.
Adding gives us 20 + 12 + 16 = 48 feet.
The answer is:

After all of the description of the climbing to the 10 mts platform, you can now see that it was all a bet, and that he was there only to probably cash that ice pop, and that all of this trip was not worth it.
The answer to your question is below
Derivative of a quotient
f'(x) = 0
g²(x) = (
Simplification and result
The significance level of difference in fhe two means is indeed 0.26.
To obtain the significance level, just standardize the mean in 2012 with the new mean and standard deviation.
The standardized score (z) is the value (x) minus the mean (xbar) then divided by the standard deviation (σ)
z = (x - xbar)/σ = (49007 - 49800)/3100 = - 0.26
Therefore, the significance level of difference is indeed 0.26.
