Answer:
No. The margin of error only includes sampling variability.
Step-by-step explanation:
The margin of error would be considered for the sampling error
In the case when some adults does not have telephones so it is called as error selection bias this is not a sampling error
The selection bias, unresponse bias and the response would be the examples of an error but it is not a sampling errors
So there is no margin of error as it only involved the variability in the sampling
Given a right triangle with the side lengths of legs = 9 and 13
For the required angle :
opposite side = 9
adjacent side = 13
so,
Answer: 161
[3×2^5+13×(−2)]+7[8−(4−9)]
Calculate 2 to the power of 5 and get 32.
3×32+13(−2)+7(8−(4−9))
Multiply 3 and 32 to get 96.
96+13(−2)+7(8−(4−9))
Multiply 13 and −2 to get −26.
96−26+7(8−(4−9))
Subtract 26 from 96 to get 70.
70+7(8−(4−9))
Subtract 9 from 4 to get −5.
70+7(8−(−5))
The opposite of −5 is 5.
70+7(8+5)
Add 8 and 5 to get 13.
70+7×13
Multiply 7 and 13 to get 91.
70+91
Add 70 and 91 to get 161.

Answer:
0.4444
Step-by-step explanation:
Use the following property to ease the calculation:
P(At least one)=1-P(None)
Total number of electrical components: 9
Number that does not function well :1
Number that functions well : 8
We have 
ways to to choose 4 good components from 8.
We have 
ways to choose 4 components from a total of 9.
If all function properly then none is bad, we 
way to do this.
P(At least one)=
P(At least one)=
P(At least one)=0.4444
