Answer:
15 ft.
Step-by-step explanation:
The tepee is a cone and its volume
= 1/3 pi r^2 h where r = radius and h = height.
The radius r = 1/2 * 10 = 5 ft.
So we have the equation:
393 = 1/3*3.14* 5^2 * h
h = 393 / (1/3*3.14*25)
= 15.02 ft.
Answer:
the bottom right
Step-by-step explanation:
Answer: 0.05
Step-by-step explanation:
- Sampling error is the error occurs by considering sample for study instead of entire population.
Given : The proportion of items in a population that possess a specific attribute is known to be 0.45.
Sample size : n= 100
Sample proportion of items in a population that possess a specific attribute : 
Now, the formula to find the sampling error :



Hence, the sampling error =0.05
2t/5=8t/20 (both numbers multiplied by 4)
t/4=5t/20 (both numbers multiplied by 5)
3=60/20
⇒ 8t/20 - 5t/20= 60/20
3t/20=60/20
⇒3t=60
t=60:3
t=20
I hope you understand !
