This is how you find the mean of a number:
To find the mean of a number, you need to add up all the numbers listed (so, 5, -11, 7, 12, -1 and 0) and then divide it by the amount of numbers there are listed. 5 + -11 + 7 + 12 + -1 + 0 equals 12, and since there are 6 numbers you then divide 12 by 6. 12 divided 6 is 2.
So the answer is A. I hope this helped you!
Answer:
Step-by-step explanation:
√12
Try putting it in your calculator. What digit comes next? Any number you pick from 0 to 9 is a guess. That's one of the ways you can tell if a number is irrational or not. You could get the answer from the calculator that came with windows. It gives the answer to 18 digits, but you'd still be guessing the 19th one.
The others are all well behaved in comparison.
Answer:
upper and lower results have to be the same
so set them equal
5x = 2x + 1
subtract 2x on each side
3x = 1
devide each side by 3
x = 1/3
You are welcome
Answer:
Yes your friend is correct.
Step-by-step explanation:
This can become very complex when trying to explain but essentially, opposite angles like angle 4 and 6 or the 103 degree and angle 2 would have the same angle measurement. Since angle 2 and 6 are on the same straight line with lines a and b being parallel, we know that that angle 2 and 6 are equal. Since we know that angle 2 and the 103 degree angle are equivalent, we can conquer that angle 6 equals 103 degrees.
D.) 52%, this is because there are 11 odd numbers for 1 to 21, so the fraction is 11/21, which is approximately 52%
