Answer:
Mean = 272.3
sd = 37.7
Step-by-step explanation:
Mean = sum/n
(221+248+251+255+259+263+264+272+291+297+374) ÷ 11
= 2995/11
= 272.2727273
Variance = (sum of x²)/n - mean²
[(221²+248²+251²+255²+259²+263²+264²+272²+291²+297²+374²)/11] - (2740/11)²
= (831067/11) - (2995/11)²
= 1419.107438
sd² = variance
sd = sqrt(1419.107438)
sd = 37.67104243

Answer:
Expanded form of
= 3000 + 180 + 12
Step-by-step explanation:
Expanded form of any number is important in math as it allows us to look at a number and identify the value of each digit.
We can write a whole number 532 in a expanded form as:
![532 = 500 + 30+2](https://tex.z-dn.net/?f=532%20%3D%20500%20%2B%2030%2B2)
![6 \times 532 = 6 \times (500+30 + 2)](https://tex.z-dn.net/?f=6%20%5Ctimes%20532%20%3D%206%20%5Ctimes%20%28500%2B30%20%2B%202%29)
= ![3000 + 180 + 12](https://tex.z-dn.net/?f=3000%20%2B%20180%20%2B%2012)
Therefore, the expanded form of
is, 3000 + 180 + 12
