First we have to find the mean (average)
mean = (564 + 1000 + 848 + 1495 + 1348) / 5 = 5255 / 5 = 1051
now we subtract the mean from every data point, then square it
564 - 1051 = -487......-487^2 = 237169
1000 - 1051 = -51......-51^2 = 2601
848 - 1051 = -203......-203^2 = 41209
1495 - 1051 = 444......444^2 = 197136
1348 - 1051 = 297......297^2 = 88209
now find the mean of the results.....but know when ur dealing with a sample instead of the whole population, u divide by 1 number less...so instead of dividing by 5, u divide by 4.
(237169 + 2601 + 41209 + 197136 + 88209) / 4 = 566324 / 4 =
141581.....this is called ur variance
now take the square root of the variance and u have ur standard deviation
sqrt (141581) = 376.272 rounds to 376.27 <==
They both equal so symbol is "=" they have LCM of 3 .
Since a line =180 degrees you could set it up as (180-85) and you would get <u><em>95.
Hope this helps!!!</em></u>
Answer:
17 blue eggs and 23 purple
Step-by-step explanation:
what we do is very simple
2 eggs one of each = 5
Then we distribute 97
b = (90/2 + 1 + 1) /3 p = (90/2 + 1) /2
b = 47/2 p= 46 /2
b = 17 p = 23
1)Add up the numbers and variables.
2) Triangles equal 180 degrees.
3)Subtract the total of the numbers and 180.
4) Then divide by the variable.
X= -10
