Assume standard deviation of all invoices is $200. Sample 100 invoices. What is the standard deviation of xbar

posledela

Answer:

Step-by-step explanation:

Standard deviation of the mean is expressed as:

SM = s/√n

s is the standard deviation of all invoices

n is the sample size of the invoiced

Given

s = $200

n = 100

Required

Standard deviation of the mean

Substitute the given parameters into the given equation

SM = 200/√100

SM = 200/10

SM = 20

Hence the standard deviation of xbar is 20

1. Determine the degree of homogeneity of the function S(x,y) = x^2 y + xy^2, and show that Euler's Theorem holds. 24 zvy

Dmitrij [34]

Answer:

Degree $k=3$

Step-by-step explanation:

The function that you have is a homogeneous function of degree $k=3$ . In fact, if $\lambda \in \mathbb{R}$ and $(x,y) \in \mathbb{R}^{2}$ we have that:

$s(\lambda x, \lambda y)=(\lambda y)(\lambda x)^{2}+(\lambda x)(\lambda y)^{2}=\lambda^{3}x^{2}y+\lambda^{3}xy^{2}=\lambda^{3}s(x,y)$

To verify that the Euler Theorem holds we need to show that:

$x\frac{\partial s}{\partial x}+y\frac{\partial s}{\partial y}=3 s(x,y)$ .

To do that let's compute the partial derivatives:

$\frac{\partial s}{\partial x}=2xy+y^2$

$\frac{\partial s}{\partial y}=x^2+2xy$

Then,

$x\frac{\partial s}{\partial x}+y\frac{\partial s}{\partial y}=2x^{2}y+xy^{2}+yx^{2}+2xy^{2}=3xy^{2}+3x^{2}y=3(x^{2}y+xy^{2})=3s(x,y).$

118.380 round to the nearest hundred

anygoal [31]

<u>1</u>18.380 to the nearest hundred is <u>1</u>00
The 1 that I underlined represents the hundreds place of a number, and since the number in the tens place ex.) 2<u>1</u>2.31 is also a 1, then you round down to just 100.
ex.) round to the nearest hundred: 492.341 The answer to this would be 500, since the number in the tens place is a 9 so you round up to the next hundred.
