Answer:

E. 72.7

Step-by-step explanation:

Here, we need to figure out the proportion of the population, which is higher than 20.  

Now, in this statement, the data set of the population is explicitly given, so the sample is irrelevant.

Here, the set of data is :  5, 33, 25, 55, 96, 75, 23, 69, 37, 17, 12.

Among this given data set of 11, The numbers which are higher than 20 are {33, 25, 55, 96, 75, 23, 69, 37}.

So, here 8 numbers are present in this data set which are greater than 20.

So for finding out the proportion, the calculation will be:

Calculation:

\frac{8}{11} * 100 = 72.72%

Therefore we get from the calculation that the population proportion, which is higher than the number 20, is 72.72% or 72.7%.

An airplane must clear a 60-foot pole at the end of a runway 500 yards long determine the angle of elevation at which the airpla
Marat540 [252]

Answer:

2.3 degrees.      

Step-by-step explanation:

Please find the attachment.

We are told that an airplane must clear a 60-foot pole at the end of a runway 500 yards long.

Let us convert 500 yards to feet.

1 yard= 3 feet.

500 yards= 3*500 feet= 1500 feet.

We can see from our attachment pole and runway are in form of a right triangle. The pole is opposite to angle of elevation of plane and length of runway is adjacent.

Since tangent represents the relation between opposite and adjacent of right triangle, So we will use tangent to find angle of elevation that plane must ascend to clear the pole.  

tan(\theta)=\frac{60}{1500}    

\theta=\tan^{-1}(\frac{60}{1500} )

\theta=\tan^{-1}(0.04)

\theta=2.290610042639

Therefore, the airplane must ascend 2.3 degrees to clear the pole.
