18-r
Difference is subtraction.
Answer:
2,704 / 6.5 = 416 mph
Step-by-step explanation:
(Distance traveled) / (Hours spent traveling) = (Distance traveled in one hour)
Line KA is not perpendicular to line JB because the angle IHE is some acute angle.

Answer:
Since 36.25 is less than 42.56, we do not reject H_o.
Step-by-step explanation:
Given n=30, s^2=0.0005
The test hypothesis is
H_o:σ^2=0.0004
Ha:σ^2 not equal to 0.0004
The test statistic is
χ^2= (n-1)×s^2/σ^2 = (30-1)*0.0005/0.0004=36.25
Given a=0.05, the critical value is χ-square with 0.95, d_f=n-1=29= 42.56 (check χ-square table)
Since 36.25 is less than 42.56, we do not reject H_o.
So we can conclude that the population variance specification is being violated.
