The ladder is making a right triangle so just use sin, cos, and tan to find either of the unknown angles.
(a) Using sin, you can find the missing angle and come up with the equation sin<span>ø = 9.2/10
</span><span>ø=80 degrees
</span>(b) Using a different triangle where the height of the building is unknown but all the angles are known. You can use cos to find the length of the base of the triangle.
cos75=x/10
x=9.2 ft
Answer:
d. H0 : pˆ = .6, Ha: pˆ > .6
Step-by-step explanation:
Given that a minister claims that more than 60% of the adult population attends a religious service at least once a month.
Here the subject of interest about a proportion of adult population who attends a religious service at least once a month.
The claim is this proportion is greater than 60% and we want to check whether this claim is true.
Hence hypotheses would be for proportion only and not mean.
Since population proportion is to be checked we use p hat
Correct answer is
d. H0 : pˆ = .6, Ha: pˆ > .6
