Answer:
3.96
Step-by-step explanation:
Standard Deviation quantifies how diverse the values of your data set are and is useful in determining how your numbers are different from each other.
Step 1: Collect your data to form a data set from which you wish to calculate a standard deviation.
5 9 17 11 8 11 16
Step 2: Calculate the mean of the data set;
5 + 9 + 17 + 11 + 8 + 11 + 16 = 77
Mean = 77 / 7
Mean = 11
Step 3: Subtract the mean from your data set and square the differences, continue with each number on your data set;
5 - 11 = (-6)² = 36
9 - 11 = (-2)² = 4
17 - 11 = (6)² = 36
11 - 11 = (0)² = 0
8 - 11 = (-3)² = 9
11 - 11 = (0)² = 0
16 - 11 = (5)² = 25
Step 4: Find the mean of the differences;
36 + 4 + 36 + 0 + 9 + 0 + 25 = 110
Mean = 110 / 7 = 15.71
Step 5: Take the square root of the Mean above to find the standard deviation;
²√15.71 = 3.96
False.
You are rounding to the nearest tenth place. With your decimal value, 3 < 5, so therefore you cannot round the 4 up to 5. Given this, your correct decimal rounded to the nearest tenth = 16.400
Answer: Socrates was condemned to death in 399 BC after he was found guilty of impiety and of corrupting the youth of Athens. When this sentence was decided upon, Socrates failed to act in his own interests and present a credible alternative to the death penalty.

Answer: 22
Step-by-step explanation: the diameter is twice radius so you multiply 11 x 2 giving you 22 as your answer
The probability of getting a 2 or a getting a black card, find individual probabilities;
A standard deck has 52 cards.
There are 4 2's in a normal deck; probability of getting it is 4/25
The probability of getting a black card is; 26/52 since half the deck is red and black.
Now add up the probabilities since it says "or"
(4/52)+(26/52)=30/52 probability of the card that you were dealt being a two or a black card.
Hope I helped :)
