Find the area of the shaded regions. Give your answer as a completely simplified exact value in terms of π (no approximations)

klemol [59]

Answer:

52 $\pi$

Step-by-step explanation:

The total shaded are will be the area of big circle - not shaded circle + little shaded circle.

The are of big shaded circle: $\pi$ $r^{2}$ So, A= $\pi$ (8^2)= 64 $\pi$

The are of not shaded circle: $\pi r^{2}$ So, A= $\pi$ (4^2)= 16 $\pi$

The are of little shaded cirlce: $\pi r^{2}$ So, A= $\pi$ (2^2)= 4 $\pi$

64 $\pi$ - 16 $\pi$ + 4 $\pi$ = 52 $\pi$

For the samples taken from two populations, the difference between the sample means does not fall within the 95% confidence inte

Scorpion4ik [409]

Answer:

Option B is right

Step-by-step explanation:

Given that there was a comparison test for two samples done. The differnce between the sample means does not fall within 95% confidence interval.

This means that there is 95% chance that there will be a significant difference between the two means.

Hence whenever we compare two samples, we find the mean difference, margin of error, and confidence interval 95%

Whenever the mean difference does not fall within the confidence interval, we find that the null hypothesis namely that the two means are equal cannot be accepted

Hence option B is true.
