Find the area of the shaded region to the nearest tenth. See picture for full problem. Please and thank you so much!
Anestetic [448]

Answer:

Step-by-step explanation:

Radius =6 ft

Area of circle = πr²

                      = 3.14 * 6 * 6

                      = 113.04 ft²

base = 10.39 ft

height = 6+3 = 9 ft

Area \ of \ triangle = \dfrac{1}{2}*base * height\\\\\\=\dfrac{1}{2}*10.39*9\\

= 46.76 ft²

Area of the shaded region = area of circle - area of triangle

             = 113.04 - 46.76

            = 66.28

             = 66.3 ft²

Serga [27]

Answer:

Yes

Step-by-step explanation:

First, suppose that nothing has changed, and possibility p is still 0.56. It's our null hypothesis. Now, we've got Bernoulli distribution, but 30 is big enough to consider Gaussian distribution instead.

It has mean μ= np =  30×0.56=16.8

standard deviation s = √npq

sqrt(30×0.56×(1-0.56)) = 2.71

So 21 is (21-16.8)/2.71 = 1.5494 standard deviations above the mean. So the level increased with a ˜ 0.005 level of significance, and there is sufficient evidence.
