The average weight of a random sample of 50 NFL players is 244.4 pounds.
<h3>What is an equation?</h3>
An equation shows the relationship between two or more numbers and variables.
For a samples size (n) in normally distributed population, the sample mean is normally distributed, with mean μX=μ and standard deviation σX=σ/√n.
Hence for a sample of 50 NFL players with an average weight of 244.4 pounds:
Mean = mean = 244.4 pounds
The average weight is 244.4 pounds.

Answer:
100 of the baloon will fill up the tank
Step-by-step explanation:
use volume of sphere formula ;
(pi/6) x diameter cubed
write your answer to 1 decimal place
then divide the volume of tank bye the volume of the baloon
you'll get 100, if you rounded up your answer to 1 decimal place
Answer:
Step-by-step explanation:
<u>For visible light:</u>
-We can see it. We use visible light to see everything around us, with our eyes at least.
-Visible light has a lower energy than UV light. UV light is what gives us sunburn.
<u>For both:</u>
-They are both forms of electromagnetic radiation (light). They are simply at different energy values and wavelengths. Our eyes can only see the visible part of the spectrum, hence why it is called the "visible" part.
-They are both emitted by the Sun. The Sun lets off many types of radiation.
<u>For UV light:</u>
-UV light is very high in energy relative to visible light. Visible light doesn't give us sunburn, but UV light will. This is what we use in tanning beds.
-UV light cannot be seen with our eyes because it does not fall into the same category as visible light.
Answer:
A = 400 cm^2
Step-by-step explanation:
The perimeter of a square is given by
P = 4s where s is the side length
80 = 4s
Divide each side by 4
80/4 = 4s/4
20 =s
We want to find the area of the square
A = s^2
A = 20^2
A = 400 cm^2
