The mean is the average, which is the sum of all the numbers divided by the total numbers there are. I will add them up for you, and then work from there.
184 + 192 + 164 + 200 = 740.
There is 740cm total, but now we need to divide by how many students we have. We have 4 students total.
740/4 = 185.
Your average (mean) height of the students is 185cm.
I hope this helps!

Answer:
Option A.
Step-by-step explanation:
Area of a square is
.... (1)
where, x is side length.
The length of each side of his square plot is decreasing at the constant rate of 2 feet/year.
It is given that bob currently owns 250,000 square feet of land.
Fist find the length of each side.
Taking square root on both sides.
Differentiate with respect to t.
Substitute x=500 and 
in the above equation.
Farmer bob is losing 2,000 square feet of land per year.
Therefore, the correct option is A.
Answer:
65 feet below sea level.
Step-by-step explanation:
With the information provided, we can create the following equation for the position of the sea lion (p)
p = 3x - 10
In this equation, x would be the final position of the seal when it caught the fish. Since we are told that the seal's position is 25 feet below sea level then we can plug in this value as x and solve for p...
p = (3 * 25) - 10
p = 75 - 10
p = 65
Finally, we can see that the sea lion's position is 65 feet below sea level.
