Answer:
The population is all the adult men who are 40 to 60 years of age and live in the United Stades.
Step-by-step explanation:
The population is all the adult men who are 40 to 60 years of age and live in the United Stades.
The 1338 are the sample, and the study wants to find the proportion of all these adults who had seen their family doctor. Since 1338 is a large sample size, this proportion can be extended to all the adult men who are 40 to 60 years of age and live in the United Stades.
You could substitute with 6 for x+9 and 9 for x+6 , otherwise it be 0=-3 or no solution
Complete Question
A person standing 213 feet from the base of a church observed the angle of elevation to the church's steeple to be 33 ∘. Find the height of the church
Answer:
138.3 ft
Step-by-step explanation:
We solve this question above using using the Trigonometric function of Tangent.
tan θ = Opposite/Adjacent
Where:
Opposite = Height of the church = x
Adjacent = Distance for the base of the church = 213ft
Angle of elevation θ = 33°
Hence:
tan 33 = x /213 ft
Cross Multiply
x = tan 33 × 213 ft
x = 138.32381735 ft
x = Opposite Approximately = 138.3 ft
Therefore, the height of the church = 138.3 ft
