Two angles are complementary. One angle is twice as large as the other angle. What is the measure of each angle?

pashok25 [27]

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

Football Air Pressure During the National Football League’s 2014 AFC championship game, officials measured the air pressure on 1

lord [1]

Answer:

The null hypothesis is: $H_0 :\mu = 12.5$

The alternative hypothesis is: $H_a :\mu$

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.

Therefore, the null hypothesis is: $H_0 :\mu = 12.5$

The required alternative hypothesis is: $H_a :\mu$

The volume of a cones is 6 pie, if a cylinder has the same diameter and height as the cone what is it's volume?

Luden [163]

$\bf \begin{array}{llll}
\textit{volume of a cone}\\\\
V=\cfrac{\pi r^2 h}{3}
\end{array}\qquad \qquad\qquad
\begin{array}{llll}
\textit{volume of a cylinder}\\\\
V=\pi r^2 h\implies 3\left(\frac{\pi r^2 h}{3} \right)
\end{array}$

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.
