Knowing that a square gives the optimum area;
120=s²
√120=s
√2×2×2×5×3=s
2√2×3×5=s
2√30=s
Therefore, the length should be ≈10.95"
Hope I helped :)
Answer:
around 56-57
Step-by-step explanation:
Yes they are
When a research question asks you to find a statistical sample mean (or average), you need to report a margin of error, or MOE, for the sample mean. The general formula for the margin of error for the sample mean is the population standard deviation, n is the sample size, and z* is the appropriate z*<span>-value for your desired level of confidence
</span>1.Find the population standard deviation and the sample size, n<span>.
</span><span>2.Divide the population standard deviation by the square root of the sample size.
</span>3.Multiply by the appropriate z*<span>-value.

Answer:
x=1
Step-by-step explanation:
- choose a side to get rid of so since its easier to take 6 away from seven we will do that but remember what you do to one side you have to do to the other
- so take away 6x from the left that leaves 0 your equation should look like this 4=-3+7x remember that we have to to it to the right side too
- so take 6x away from the 7x on the right side and that leaves 1x so it should look like this 4=-3+1x
- then since it's a -3 you will need to add 3 for it ton equal 0 so it will look like this 4=7x
- but dont for get to do the same to the other side so add 3 to the 4 on the left so it will look like this 7=7x
- then divide by 7 to get x by itself so it will look like this 7=x
- but you aren't done yet you still have to divide the left by 7 so it will look like this 1=x
and thats all there is to it hope this helps
F'(x, y) = 8x -3xydy/dx +12y²dy/dx = 0
(12y² -3xy)dy/dx = -8x
dy/dx = -8x/[12y² -3xy]
dy/dx |(x=-1 , y=-3) : = -8(-1)/[12(-3)² - 3(-1)(-3)]
= 8/[108 -9]
=8/99
