Answer:
Because of traffic, she averaged only 15 miles per hour on the way there but ... If the total travel time was 2 hours how long does it take her to drive to ...
Step-by-step explanation:
Answer:
slope(m)=change in y/change in x
6=y-(-1)/x-4
6=y+1/x-4
6(x-4)=y+1
6x-24=y+1
6x-24-1=y
6x-25=y
hence this is the equation
Answer:
Since the calculated value of F = 1.4397 is less than the critical value of
F (9,9)= 2.4403 we conclude that the first instructor's variance is smaller and reject H0.
Step-by-step explanation:
1)Formulate the hypothesis that first variance is equal or greater than the second variance
H0: σ₁²≥σ₂² against the claim that the first instructor's variance is smaller
Ha: σ₁²< σ₂²
2) Test Statistic F= s₂²/s₁²
F= 84.8/ 58.9= 1.4397
3)Degrees of Freedom = n1-1= 10-1= 9 and n2 = 10-1= 9
4)Critical value at 10 % significance level= F(9,9)= 2.4403
5)Since the calculated value of F = 1.4397 is less than the critical value of
F (9,9)= 2.4403 we conclude that the first instructor's variance is smaller and reject H0.
Answer:
R = 6
Step-by-step explanation:
Remember... Circle area is:
A = pi×R^2
Where R is the circle radius.
Then,
Pi×R^2=36×Pi
R = square root of 36
R = 6
