Answer:
The distance between the givens points is 9 unit
Step-by-step explanation:
Given points are as :
A = ( 1 , 5 )
B = ( 1 , - 4 )
So, The Distance between points A and B = AB
Now, From Distance formula
AB = 
Or, AB = 
Or, AB = 
Or, AB = 
= 9
Hence The distance between the givens points is 9 unit Answer
Answer:
I think its 0.007 but I'm not sure or its 0.01
35,725
this is because u can take the ratio 7+5+9=21 then take 150,045/21 which u get 7,145 then time 5 and u get 35,725
Solution:- Given that the total revenue function
,where x is the number of rooms filled
Now, differentiating the function w.r.t. x,we get
To find critical points ,Put

Answer:
(80.4942, 94.9052)
Step-by-step explanation:
The sample mean is x = 87.7.
The sample standard deviation is s = 11.26.
At 99% confidence and 19 degrees of freedom, the critical value is t = 2.861.
The confidence interval is:
x ± t (s/√n)
87.7 ± 2.861 (11.26 / √20)
87.7 ± 7.2053
(80.4947, 94.9053)
