Answer: There is a 90% chance that the error range will be with in 3.29 ft² .
Step-by-step explanation:
Given : The area of a parking lot is calculated to be 5,474 ft² .
Estimated standard deviation = 2 ft²
The critical z-value for 90% confidence interval is 1.645 (from z-table)
Then, the Maximum Anticipated Error = ( critical z-value ) x ( standard deviation )
= 1.645 (2) =3.29 ft²
i.e. Maximum Anticipated Error = 3.29 ft²
Hence, there is a 90% chance that the error range will be with in 3.29 ft² .
Answer:
∠ MON = 128°
∠ LOM + ∠MON = ∠ LON , substitute values
3x + 43 + 8x + 104 = 180, that is
11x + 147 = 180 ( subtract 147 from both sides )
11x = 33 ( divide both sides by 11 )
x = 3
Thus
∠ MON = 8x + 104 = 8(3) + 104 = 24 + 104 = 128°
