The standard deviation of the means measure describes the standard error of the mean
Statistic is the study of mathematics that deal with relations between comprehensive data.
A standard deviation (or σ) is a measurement of how spread the information is in relation to the mean. A lower standard deviation means data are bunched around the mean, and a high standard deviation implies data are more scattered out, and best describes the error related to or around the mean.
From the above definition it is clear that standard deviation of the means measure describes the standard error of the mean.
Thus, the standard deviation of the means measure describes the standard error of the mean

If f(x)=x^2-2x+11, find f (-2)
Answer: f( -2) = 19
Step-by-step explanation:
plug '-2' into every place 'x' is in
so the new equation would be
f(-2) = (-2)^2 - 2(-2) + 11
and now solve :)
f ( -2) = 4 - ( -4) + 11
f (-2) = 4 + 4 + 11
f ( -2 ) = 19

Sally's income per month is $1500. She wants to create a budget to be able to afford everything. How much can she spend on "fun" things if she has to pay $500 a month for rent, $50 for phone bill, $100 for groceries, $100 for miscellaneous bills. and $300 for a car payment.
Answer:
450$
Step-by-step explanation:
So lets add otgether everything that she NEEDS to buy, to see how much of 1500$ she can use on what she WANTS to buy.
So:
500+50+100+100+300
=
1050
This is the total cost of what she NEEDS to buy
Now lets subtract this from her income:
1500-1050
=
450
So we now know that the amount of money she has left to spend on what she WANTS is 450$

please answer I'll give you five stars and step by step
Answer:
[tex]A= 2400\\P= 1200\\r = 6.5\% = 0.065\\n = 365 \\t = t\\A = P(1 + \frac{r}{n})^{nt}\\\\2400 = 1200(1 +\frac{0.065}{365} )^{365t}\\\\\frac{2400}{1200} = (1.00017808219)^{365t}\\\\(2)^{\frac{1}{365} } = (1.00017808219)^t\\\\\\Taking \ log \ on \ both \ sides\\log(1.00190083768) = t \times log(1.00017808219)\\\\t= \frac{log(1.00190083768)}{log(1.00017808219)} = 10.66\\\\t = 10.7years[/tex]

You won $1000 in a radio contest. If you invest it in an account that pays 4.5% interest compounded semiannually, what will be your balance after 4 years?
please answer I'll give you five stars
Answer:
[tex]A= P( 1 + \frac{r}{n})^{nt}\\[/tex]
P = 1000
r = 4.5% = 0.045
n = semi annually = 2
t = 4
[tex]A= 1000( 1 + \frac{0.045}{2} )^8 =1000(1 +0.0225)^8= \$ 1194.83[/tex]

the area for this circle is given as
144π m^2
144 is the squared form of 12 if the radius is 12 the diameter is 24
1417= 4/3*pi*r^3
