Answer:
The standard deviation is 10.38
Step-by-step explanation:
Given;
Variance, v = 107.76
mean, x = 34.2
The standard deviation is given by;
standard deviation = √variance
standard deviation = √107.76
standard deviation = 10.381
standard deviation = 10.38 (two decimal places)
Therefore, the standard deviation is 10.38
Answer:
x = 5
Step-by-step explanation:
The 2 strokes through XM and MY indicate the segments are congruent, so
YM = MX , that is
8x - 24 = 3x + 1 ( subtract 3x from both sides )
5x - 24 = 1 ( add 24 to both sides )
5x = 25 ( divide both sides by 5 )
x = 5
