Answer: The answer is B

Step-by-step explanation: 122 >7 (z+8) -5 (6+z). Then switch them, 7 (z+8) -5 (6+z) <122. Expanded:  7 (z+8) -5 (6+z) <122:v 2z+26

2z+26<122, subtract 26 from both sides: 2z+26-26<122-26

Simplify: 2z<96, divide both sides by 2: 2z over 2 < 96 over 2

and finally simplified: Z<48

What is the Mean Average deviation from the Mean?<br> Numbers: 6, 2, 3, 3, 2, 2
Irina-Kira [14]

Answer:

2.42

Step-by-step explanation:

standard deviation= sqrt(variance)

Variance=E[X2] - E[X]2

E[X] = sum(X)/n=35/9, so E[X]2 = 1225/81

E[X2] =sum(X2)/n = 189/9 = 170/81

Variance= 476/81

Standard deviation = sqrt(476/81) ~2.42
