Angles that are complementary end up equally 90 degrees. That means 30 degrees is one and 60 is the other because 30*2 = 60
60+30=90
Using the Pythagorean Theorem, you should get 45 [9 + 36]. Then, take the square root of 45 and simplify it to 3√5.
Answer:
The null hypothesis is: 
The alternative hypothesis is: 
Step-by-step explanation:
Consider the provided information.
It is given that the average air pressure in footballs used by the Patriots was significantly less than the allowable limit of 12.5 psi.
The null hypothesis indicates that there is no substantial difference between given populations, due to sampling or experimental error, any observed difference.

The required alternative hypothesis is: 
Answer: .875
Step-by-step explanation:
7/8= decimal point 875

now, notice, the volume of the cylinder is really about the same as the volume of a cone, just 3 times larger, assuming "h"eight and "r"adius for both is the same amount.
now, if we know the cone with that "h" and "r" has a volume of 6π, the cylinder is.... well, you already know.
