Answer: (0.093,0.267)
Step-by-step explanation:
The confidence interval for the difference in proportion is given by :-
Given : ;
Proportion of men said they wore seatbelts =
Proportion of women said they wore seatbelts =
Significance level :
Critical value :
Now, the 95% confidence interval for the difference in proportion of men and women who wear seatbelts will be :-
Hence, the 95% confidence interval for the difference in proportion of men and women who wear seatbelts = (0.093,0.267)
8x11=88
88x3=264
so it would take him 264 minutes or 4 hours and 30 minutes
hope this helps you out friend!
Answer:
x=7/2
Step-by-step explanation:
According to Statement,
√2(x+1)=3
Taking square on both sides,
2(x+1)=9
2x+2=9
2x=9-2
2x=7
x=7/2
Answer:
28.8 ft
Step-by-step explanation:
SOH CAH TOA reminds you that ...
Tan = Opposite/Adjacent
The height to the top of the antenna is opposite the angle of elevation, and the distance to the building is adjacent. So, we have ...
tan(58°) = (160 ft +antenna height)/(118 ft)
(118 ft)·tan(58°) = 160 ft + antenna height . . . . . . . multiply by 118 ft
188.8 ft - 160 ft = antenna height = 28.8 ft . . . . . . subtract 160 ft, evaluate
The height of the antenna is 28.8 ft above the top of the building. (The total height of building + antenna is 188.8 ft.)
