Answer:

Because u would have to find the undercorse of 010-1 witch makes the out of part by 6

Explanation:

Given :

Juan rolled a six-sided number cube 18 times.

The number two occurred four times.

To Find: Juan claimed the experimental probability of rolling a two was approximately 1/9. Why is Juan’s experimental probability incorrect?

Solution:

Total events = number of times cube rolled = 18

Favorable events = The number two occurred four times.  = 4

So, Experimental probability of rolling a two was approximately 1/9

Choose the molecule with the strongest internal bond, (intra-, not intermolecular bond) ​
Verdich [7]

Answer:

A

Explanation:

The molecule with the strongest intramolecular bond is HF. Hydrogen fluoride is the answer due to the strong and highly electronegative nature of Fluorine.

  • Fluorine is the most electronegative element in nature.
  • When it combines with other substances, due to its electronegative property, it draws most of the electrons closest to itself in the bond.
  • This tendency and ability makes the shared electrons closer the fluorine in the bond.
  • The strong polarization that ensues confers a very strong covalent bond pair on the bond formed.

Protozoan infection is not likely to be transmitted by:
anygoal [31]
Hi! 

The answer is breathing.

Protozoans are organisms that can multiply themselves in humans, and serious infections can develop from one organism. The most frequently transmission methods are contaminated food or fecal contact. Dog bites inoculate bacteria into deep tissue, and they also serve as a transmission method.

Breathing
is not considered to be likely to transmit protozoan infection because protozoans rarely develop in the respiratory tract.

If a sample has 25% parent and 75% daughter, how many halflifes have gone by?
Anit [1.1K]

Answer:

Two half lives.

Explanation:

It is known that the decay of isotopes and radioactive material obeys first order kinetics.

Also, it is clear that in first order decay the half-life time is independent of the initial concentration.

That means for a sample 100% to decay to 50 % it will take one half-life, and to decay the remaining 50% to 25% it will take another half-life.

So, for a sample has 25% parent and 75% daughter it will have two half-lives.
