Answer:

Step-by-step explanation:

it looks like an isosceles triangle, 2 equal side and 2 equal angles (F&E)

the sum of the interior angles in a triangle is 180°, and FH is 180°.

180 - 120 = 60° (angle G)

now we know that it is an equilateral triangle, so Y and 2x are 60°

(3 * 60 = 180°)

-------------------------------

180 - 60 = 120

120 : 2 = 60°

Answer:

$\large\boxed{V=\dfrac{1600\pi}{3}\ cm^3}$

Step-by-step explanation:

The formula of a volume of a cone:

$V=\dfrac{1}{3}\pi r^2H$

r - radius

H - height

We have r = 10cm and H = 16cm. Substitute:

$V=\dfrac{1}{3}\pi(10^2)(16)=\dfrac{1}{3}\pi(100)(16)=\dfrac{1600\pi}{3}\ cm^3$

Anarel [89]

Answer:

a) There is suggestive evidence the velvet leaf seed is successful at weed control.

b) Lower bound: 3.699 Upper bound: 6.629

c) Since the confidence interval contains the average percent of seeds to be infected by the beetle (5.164), so we fail to reject the null hypothesis at the specified level of significance.
