Answer:
The distance from he ball to the goal is 11.85 feet (Approx) .
Step-by-step explanation:
As given
The angle of elevation from a soccer ball on the ground to the top of the goal is 34° .
If the goal is 8 feet tall.
Now by using the trigonometric identity .
As shown in the diagram given below
Perpendicular = AB = 8 feet
Base = BC
Put all the values in the identity .
BC = 11.85 feet (Approx)
Therefore the distance from he ball to the goal is 11.85 feet (Approx) .
To find the test statistic or z-score given sample number (n), sample mean (x), standard deviation (σ), and population mean (μ), we can use
Given that n = 36, x = 24.6, μ = 20, and σ = 12,
From this, we see that the test statistic is 2.3.
Answer: 2.3
