The height of the chimney above the floor of the observation deck is 52.4 ft
Two right angle triangle will be formed.
<h3>Right angle triangle:</h3>
Right angle triangle are triangle that has one of its angle as 90 degrees.
Therefore, using trigonometric ratio,
adjacent side = distance of observer from the bottom edge of the Delaware River drawbridge observation deck
Therefore,
tan 40 = opposite / adjacent
Where
x = height of the observer to the top of the observation deck
tan 40 = x / 200
x = 200 tan 40
x = 167.819926235
x = 167.82 ft
tan 30 = opposite / adjacent
y = height of the observer to the bottom of the observation deck
tan 30 = y / 200
y = 200 tan 30
y = 115.470053838
y = 115.47 ft
The height of the chimney above the floor of the observation deck = height of the observer to the top of the observation deck - height of the observer to the bottom of the observation deck
The height of the chimney above the floor of the observation deck = 167.82 - 115.47 = 52.35 ft

Answer:
Step-by-step explanation:
x2+1/4x4
2x+(1/4*4x)
2x+(1/16x)
= 32x^2+1/16x
Answer:
H0 : p = 0.5
H1 : p > 0.5
Step-by-step explanation:
The the claim to test and determine if a signifant evidence for is if more than half of viewers want a return to original day time program. Since, this is
Since, p is the proportion who prefer the regular day time program;
The hypothesis to test is :
If p > 0.5 `; this represents the alternative hypothesis which we want to check if it we have significant evidence to adopt the claim.
The Null value on the other hand will take the a proportion equal to the p: and it is the initial truth until the alternative has a strong evidence to reject the null.
The null ;
H0 : μ = 0.5
