Use the cone formula:
V =  \pi r^{2}  \frac{h}{3}
And so:
Area =  \pi * 150^{2} *  \frac{240}{3} = 5654866.7 inches^{2}
5654866.7 / 12000 = 471,
So the answer is 471 weeks.

Hope this helps.

V(w)=(hpr^2)/3-12000w

V(w)=(16956000-36000w)/3

V=0 when 16956000=36000w

w=471weeks

Use the unit circle to find all values of thetabetween 0 and 2Ï€ for which sin(theta)=sqrt 3/2
ElenaW [278]
Sin(theta)=√3/2, 0≤theta≤360
In a unit circle, sin is y/r, r is always positive, y is positive in the first and second quadrant only. 
sin60=√3/2, sin120=√3/2
so theta is 60 or 120

1. A heterozygous white-fruited squash plant is crossed with a yellow-fruited plant, yielding 200 seeds. of these seeds, 110 pro
garri49 [273]

Answer:

Part 1 , not significant

Part II, significant

Step-by-step explanation:

Given that a  heterozygous white-fruited squash plant is crossed with a yellow-fruited plant, yielding 200 seeds. of these seeds, 110 produce white-fruited plants while only 90 produce yellow-fruited plants

H_0: Both colours are equally likely\\H_a: Both colours are not equally likely

(Two tailed chi square test)

We assume H0 to be true and find out expected

If H0 is true expected would be 100 white and 100 yellow

Chi square = \Sigma \frac{(O-E)^2}{E} \\=\frac{(110-100)^2}{100} +frac{(90-100)^2}{100} \\=2

df = 1

p value = 0.152799

Since p value > 0.05 at 5% level we accept that the colours are equally likely

2)

Here observed are 1100 and 900

Expected 1000 & 1000

df = 1

Chi square = \frac{20000}{100} =200

p value <0.0001

These results are here statistically significant.
