Answer:
3
Step-by-step explanation:
12/3=4
57/3=19
Cavalieri's principle states that volume formulas for pyramids and cones will also apply to both right and oblique solids, a<span>s long as the "matching" cross section areas are equal.
So we can use the formula V=bh regardless of the resulting shape.
V = bh = </span>π(15 m)²(12 m) = 2700π m³ ≈ 8482.3 m³
Answer:
Option D
Step-by-step explanation:
A type I error occurs when you reject the null hypothesis when it is actually true.
The null hypothesis in this case is minimum breaking strength is less than or equal to 0.5.
A type one error would be allowing the production process to continue when the true breaking strength is below specifications.
Answer:
70 inches
Step-by-step explanation:
Larry forms a right triangle with the ground (this is one leg of a right triangle) and he is 24 inches from his shadow (this is the second leg).
74 inches is the hypotenuse of the right triangle
use pythagorean theorem: a^2 + b^2 = c^2
let h = Larry's height
h^2 + 24^2 = 74^2
h^2 + 576 = 5476
h^2 = 4900
h = sq rt 4900
h = 70
