Ascientist claims that only 67% of geese in his area fly south for the winter. he tags 70 random geese in the summer and finds that 20 of them do not fly south in the winter. if = .05, is the scientist's belief warranted?

step-by-step explanation:

just plug in each number for x and see which ones work and don't

80π/3 or about 83.775

step-by-step explanation:

since a cone is 1/3 of a cylinder, we need to find the base's area. since area = πr^2, we get 16π. then, multiplying this by 5, we get 80π. dividing by 3, since the cone's volume is 1/3 of that of a cylinder's, we get 80π/3.

hope this !
