The probabilities:
-Two break points are selected randomly (and distributed uniformly) on the stick.
The stick is first broken into two pieces. The longest (or rather, not the shortest) is then broken into two.
-The stick is first broken into two pieces. A piece randomly selected with probability 1/2 is then broken into two.
-The stick is first broken into two pieces. A piece randomly selected with the probability proportional to its length is then broken into two.
Step-by-step explanation:
Larval mosquitoes breath through trachea in their siphons. This is a structure analogous to the snorkel on a diesel electric submarine. It allows for gas exchange with the atmosphere while the remainder of the insect is submerged. The opening of the siphon is hydrophobic so it won’t get wet and blocked by water. This works well to keep the siphon and the trachea open under normal conditions. Oil when poured on water forms a thin film. When there are mosquitos in that water, when their siphons contact the oil layer, the oil wets and blocks their siphons and suffocates the mosquitoes. This works against most, but not all mossies, as evolution is an amazing process. Some mosquitoes (Mansonia, Coquilletidia) have a siphon designed to penetrate the air vessels in aquatic plants and they don’t need to come to the surface to breath like other mossies. So oil won’t work on these genera.
28 bags if you include the cat food (which you would)
Answer:
n = - 4
Step-by-step explanation:
note that 625 =
, then
=
= 
Since the bases on both sides are equal, both 5 then equate the exponents
n = - 4
The rectangle is 7 x 4 so the area is 28 sq cm
The triangle has a base of 4 and a height of 3.
The formula is A = 1/2 * b*h
You have 2 triangles so:
2(1/2)*4*3= 12 sq cm
Add together:
28 + 12= 40 sq cm
