If a random variable has a standard deviation of σ and a sample of size n is collected for the variable, then the mean has a standard error given by σ/√n. So the standard error of the mean is calculated using the two quantities: standard deviation σ and the sample size n.
1/3 goes into 2 = 6 times
And then you have a 1/3 left over so u can make 7 batches of brownies
7 batches
First represent your 3 consecutive integers as follows.
X ⇒ <em>first integer</em>
X + 1 ⇒ <em>second integer</em>
X + 2 ⇒ <em>third integer</em>
<em />
Since their sum is 84, our equation reads x + (x + 1) + (x + 2) = 84.
Simplifying on the left side we get 3x + 3 = 84.
Now subtract 3 from both sides to get 3x = 81.
Dividing both sides by 3, we find that <em>x = 27</em>.
Finally, make sure you list all your answers.
If <em>x </em>is 27 then <em>x </em>+ 1 is 28 and <em>x </em>+ 2 is 29.
When c = 4 and it is applied to this equation, the answer is 32.

The answer would be: 128
You can find minimum value by looking at the vertex. First, differentiate the equation and find the value of x.
<span> y=2x^2-32x+256
4x - 32=0
4x=32
x=8
If you put x=8, the value would be:
</span>y=2x^2-32x+256
y=2(8)^2-32(8)+256
y= 128- 256 + 256= 128
