Need help badly #15 Find the area of each sector.

Mathematics
1 answer:
Ber [7]3 years ago
6 0

The highlighted sector is exactly 3/4 of the circle area, because \frac{3\pi}{2} is 3/4 of 2\pi which is a complete rotation.

Since you are given the radius, you can compute the area as

A = \pi r^2 = 16\pi

So, 3/4 of this area would be 12\pi squared cm.

The remaining sector, of course, is 4\pi squared cm.

What is the only way to increase power of a significance test when lowering the probability of committing a Type I error
Reil [10]

the probability of making a Type I error is equal to the significance level of power. To increase the probability of a Type I error, increase the significance level. Changing the sample size has no effect on the probability of a Type I error.

The electricity of a take a look at can be expanded in a number of methods, for example increasing the pattern length, reducing the standard errors, increasing the difference between the pattern statistic and the hypothesized parameter, or growing the alpha degree.

The chance of creating a kind I mistakes is α, that's the extent of importance you put for your hypothesis check. An α of 0.05 indicates which you are inclined to accept a five% chance which you are incorrect whilst you reject the null hypothesis. To lower this risk, you have to use a decrease cost for α

Answer:

No

Step-by-step explanation:

y

put in 9 for x

y<-\frac{1}{3} 9-2

y<-3 -2

y<-5

then put in -5 for y

-5<-5

Since they are the same number that makes the equation impossible

Hope that helps :)
