Well, this is a stem and leaf problem. 

The numbers are 20, 28, 29, 29, 31, 32, 36, 41, and 42. 

In order to solve for the mean, we find the average and we add the numbers together and divide by 9(there are 9 numbers). 

The mean is 32.
The median is the middle number, or 31.

To find the mean you have to add all of the numbers then divide by the total number of numbers so-20+28+29+29+31+32+36+41+42=288 then divide by 9=32 therefor the answer to number 1 is d
to find the median eliminate the numbers on the outside till you find the middle one
20 28 29 29 31 32 36 41 42
     28 29 29 31 32 36 41
          29 29 31 32 36
               29 31 32
                    31
therefor the median is 31

A school flag poll casts a 16 foot shadow on the lawn. A teacher stood at the shadows edge and measure the angle of elevation to
vovikov84 [41]

Answer:

30.1 feet.  

Step-by-step explanation:

We have been given that a school flag poll casts a 16 foot shadow on the lawn. A teacher stood at the shadows edge and measure the angle of elevation to the top of the poll at 62°. We are asked to find the height of the tall.

First of all, we will draw a diagram to represent our give scenario as shown in the attachment.

We can see that side length with 16 feet is adjacent side and height of the pole (h) is opposite side to angle of elevation.

We know that tangent relates opposite side of a right triangle to its adjacent side.

\text{tan}=\frac{\text{Opposite}}{\text{Adjacent}}

\text{tan}(62^{\circ})=\frac{h}{16}

h=16\cdot \text{tan}(62^{\circ})

h=16\cdot 1.880726465346

h=30.0916234\approx 30.1

Therefore, the poll is approximately 30.1 feet tall.
