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 <==
Answer:
ithe answer to your question is going to be c
Three line segments can form a triangle if the length of the longest segment is greater than the sum of the lengths of the shorter segments.
They can form a triangle.
Now if c is the length of the longest side and a and b are the lengths of the shorter sides, then:
- if
, the triangle is right
- if
, the triangle is acute
- if
, the triangle is obtuse
The triangle is obtuse.
The answer is D.

➷The answer is 742 points.
Explanation: To find the amount of points Val earns, you need to first find 30% of 1060. To do this, you could times 0.3 by 1060, and you should get 318. Since you are not finding 30% of 1060, you also need to subtract 1060 by 318, which gives you the amount of Val's points. 1060-318 is 742, so that is how many points Val earns.
