The area A of a sector of a circle is given by A=πr²s/360, where r is the radius of the circle and s is the angle measure(in deg

rees) of the sector. Solve the equation for s to find the angle measure given the radius and area of the circle.

Answer:

Step-by-step explanation:

It is given that The area A of a sector of a circle is given by:

A=\frac{{\pi}r^2s}{360}

where where r is the radius of the circle and s is the angle measure(in degrees) of the sector.

Then, the equation for s can be obtained by rewriting the above given equation, thus

A=\frac{{\pi}r^2s}{360}

{\pi}r^2s=360A

s=\frac{360}{{\pi}r^2}

which is the required equation for s to find the angle measure given the radius and area of the circle.

The average monthly cell phone bill was reported to be $50.07 by the U.S. Wireless Industry. Random Sampling of a large cell pho
zalisa [80]

Answer:

The null and alternative hypotheses are:

H_{0}:\mu= 50.07

H_{a}:\mu>50.07

Under the null hypothesis, the test statistic is:

t=\frac{\bar{x}-\mu}{\frac{s}{\sqrt{n}} }

Where:

\bar{x} = 52.86 is the sample mean

s=7.0132 is the sample standard deviation

n=10 is the sample size

\therefore t=\frac{52.86-50.07}{\frac{7.0132}{\sqrt{10}} }    

          =1.26

Now, the right tailed t critical value at 0.05 significance level for df = n-1 = 10-1 = 9 is:

t_{critical}=1.833

Since the t statistic is less than the t critical value at 0.05 significance level, therefore,we fail to reject the null hypothesis and conclude that there is not sufficient evidence to support the claim that the average phone bill has increased.
