Answer:
B. Yuri divided by n instead of n-1
Step-by-step explanation:
It was stated in the question that the dataset was sample dataset. For a sample dataset, the standard deviation is given by the formula,
σ = √ Σ (Xi - mean)²/(n - 1) where i = 1,2,3.....n
Since this is just a sample dataset and not the whole population, Yuri should have divided by n-1 instead of n.
<em>2.7 / 3 = 0.9.</em>
Is <em>0.9</em> greater than, or less than <em>1? </em>=)
Answer:
y≥-4 or (-4,∞)
Step-by-step explanation:
For this case we have the following quadratic functions:
Revenue: 
Cost: 
Then, we observe that the profit is given by the following mathematical relationship:

Substituting values we have:

Making the corresponding calculations we have:

Answer:
An expression that represents the profit is:

J
You get the same answer, you just start with (x + 3) in the second equation...
That moment when you realize you're dumb and the correct answer is F
