Yes I can :O
Mean: About 11.87
Median: 11
Mode: 10
Step-by-step explanation:
Mean: Add up all the numbers and divide by the total number of numbers
<em>*deep breath in haha*</em>
6+7+7+8+8+9+9+9+50 (the 10s)+33 (the 11s)+12+12+12+12+13+14+14+16+16+17+17+18+18+19=356
356 (total) / 30 (number of numbers) = 11.8666666666666666666666 etc = 11.87
Median: With all the numbers in order, the middle number (if there are two add them together and divide by 2)
Not much to show, just mark them off starting from the outside getting inside, you end up with 11!
- See attached
Mode: Data value that occurs most often, in this case we can see that 10 happened the most
Hope this helps, have a nice day! :D

Answer:
Step-by-step explanation:
Given:
Right ∆ with,
Hypotenuse = x
Opposite = 9
Reference angle = 39°.
Required:
The value of x
Solution:
Since we are given a reference angle with opposite length, and we are to find the hypotenuse length, x, apply the following trigonometric ratios formula:
Plug in the values into the equation
Multiply both sides by x
Divide both sides by sin(39)
(to 2 decimal places)
Part A : formula for circumference = pi*D or 2piR
for circle A.... 8*pi=25.12
therefore pi=3.14
for circle B.... 3*pi=9.42
therefore pi=9.42/3
pi=3.14
part B : formula for Area =
for circle A.... 50.24=pi*(8/2)sqr...(because diameter/2= radius)
pi=50.24/16
pi=3.14
for circle B... 7.065=pi*(3/2)sqr...
pi=7.065/2.25
pi=3.14
what do you observe?
the values for pi are all equal... therefore pi is constant.
