Answer:
Margin of error for a 95% of confidence intervals is 0.261
Step-by-step explanation:
<u>Step1:-</u>
Sample n = 81 business students over a one-week period.
Given the population standard deviation is 1.2 hours
Confidence level of significance = 0.95
Zₐ = 1.96
Margin of error (M.E) = 
Given n=81 , σ =1.2 and Zₐ = 1.96
<u>Step2:-</u>
<u />
<u />
<u />
<u />
On calculating , we get
Margin of error = 0.261
<u>Conclusion:-</u>
Margin of error for a 95% of confidence intervals is 0.261

The ends of the rectangle = 10*10*2 = 200
The long sides and bottom of the rectangle = 12*10*3 = 360
Vertical end of the triangle = 5*10 = 50
The sides of the triangle = 12*5*1/2*2 = 60
Triangle slope = 13*10 = 130
Total = 200 + 360 + 50 + 60 + 130 =
800 in sq
The height of the flag pole is 51 ft.
Solution:
Paul creates the smaller triangle and flag pole creates the larger triangle.
Base of smaller triangle = 10 ft
Height of smaller triangle = 6 ft
Base of the larger triangle = 85 ft
Let the height of the flagpole be h.
Multiply by 85 on both sides.
⇒ 51 = h
The height of the flag pole is 51 ft.

608,000
you go to thousands look next number left and round up or down and the rest after the thousands becomes zeros
Answer:
Step-by-step explanation:
<u>We need to find the difference in progress:</u>
- 1/3 - 2/8 =
- 1/3 - 1/4 =
- 4/12 - 3/12 =
- 1/12
The first student is 1/12 ahead
