Answer: E. none of the above
Step-by-step explanation:
The given data values that represents the population:
2, 6, 3, and 1.
Number of values : n=4
Mean of the data values = 
Sum of the squares of the difference between each values and the mean =
Now , Variance = (Sum of the squares of the difference between each values and the mean ) ÷ (n)
= (14) ÷ (4)= 3.5
Hence, the variance is 3.5.
Therefore , the correct answer is "E. none of the above".
Answer:
6.557377049 but if simplified put either 6.5 or 6.6
Step-by-step explanation:
20 divided by 305 is 0.065. 0.065 times 100 is 6.5 or 6.6. Hope you pass.
Answer:
B. 
Step-by-step explanation:
The transformations are:
Reflected upon the x axis (x is now negative):
Moved 4 units to the right (instead of just the variable x, you have (x-4)):
And finally moved 3 units down (so now it's minus 3):
Hope this helps! :]
No - there is a rule that state that the sum of two sides of a triangle must be greater than the 3rd side.
While 9+15 >4
and 4+15 >9
9+4 is not greater than 15 - so this triangle cannot be made.
