Asample of 5 hotels reported the price for a night's stay:
$189 $219 $259 $329 $129
what is the range of the prices of a night’s stay? how to find the standard deviation of the nightly prices

a) Range = 200

b) Standard Deviation = 75.03

Step-by-step explanation:

Prices: $189 $219 $259 $329 $129

a) Range

Range = Maximum value - Minimum value

Maximum value = 329

Minimum value = 129

So, Range = 329 - 129

Range = 200

b) Standard Deviation

The formula used for finding standard deviation is:

N is No of terms

μ is mean

Mean μ = (189+219+259+329+129)/5 = 225

x              x-μ                  (x-μ)^2

189      189-225= -36      1296

219      219 - 225= -6       36

259     259-225= 34       1156    

329      329-225=104      10,816

129       129-225=-96        9216

Now, find

Now finding standard deviation

i believe the correct answer is option 4.principalities were small territories that were run by russian rulers.

which statement correctly defines principalities in northern asia in the 1200s? principalities were small territories that were run by russian rulers.

hope i could ! : )

step-by-step explanation:

given the function as;

write the equation replacing f(x) with y

form   and fill a table containing values of y with corresponding values of x

you can take a range for   values of x as -3≤x≤3

solving for x=-3

for x=-2

repeat the same procedure to get the values of y for the remaining ,x=-1 to x=3

plot the values of y against values   of x and obtain the following graph
