Answer:
Step-by-step explanation:
√13.7/(3.05^2+2.6)
Answer:
3
Step-by-step explanation:
Mean = (3+7+-1+1+0+5+-3+2+-1+6+5+-2)/12
= 1.833
median is middle of ordered numbers -3/-2/-1/-1/0/1/2/3/5/5/6/8/7 here between the 6th and the 7th since with even number sample, there is not a unique middle. This would be 1.5
Standard deviation = √ 123.67/12
√10.3
=3.21
the change score that is 2.2 standard deviations below the mean.
1.83 - 2.2(3.21)
= 5.232

Answer:
x + 10 = x
Has no solution because when you simplify it, you get
10 = 0 which is a false statement
2x + 4 = 2x
Has no solution
Because if reduces to 4 = 0
