112.5 miles because 4x25=100 and half of 25 is 12.5 so 100+12.5= 112.5
technically 4.5x25=112.5
Answer:
x > 4/3
Step-by-step explanation:
The first inequality can be solved this way ...
3x -91 > -87
3x > 4 . . . . . . . add 91
x > 4/3 . . . . . . divide by 3
__
The second inequality has solution ...
21x -17 > 25
21x > 42 . . . . . . add 17
x > 2 . . . . . . . . . divide by 21
__
The solution set is the union of these overlapping solutions, so will be equal to the first solution:
x > 4/3
Answer:
a.
b-Check illustration below
c.(-0.0517,0.0177
Step-by-step explanation:
a.let 
denote processes 1 & 2.
For 
: T1=10,n1=200
For 
:T2=20,n2=300
Therefore
b. To test for hypothesis:-
i.
ii.For a two sample Proportion test
iii. for 
(0.5 alpha IS 0.025),
reject 
if
iv. Do not reject . The noncomforting proportions are not significantly different as calculated below:
z=-0.78
c.
for the p1-p2 is given as:
=(-0.0517,+0.0177)
*CI contains o, which implies that proportions are NOT significantly different.
