Explanation:
Characteristics of Carbohydrates:
Carbohydrates are chemical compounds that contain oxygen, hydrogen, and carbon atoms.
They have the general chemical formula Cn (H2O) n or are derivatives of such. ...
They contain large quantities of hydroxyl groups.
The standard deviation of the average age of a breed of dog is said to be 3.69.
<h3>What is the standard deviation about?</h3>
Note that we take:
- x = dog age has mean 19.5
- Unknown standard deviation.
Hence:
z = (x - mean) /SD is distributed N (0,1) - mean o standard deviation 1 (standard normal)
Since 20% of dogs are known to be older than 22.6 years:
So 22.6 years is said to be 80th percentile,
Since z matching to 80th percentile (using the standard normal table) s is <em>0.84.</em>
Then one need to plug z, x which is = 22.6
mean = 19.5 into the stated z equation:
Hence,
0.84 = (22.6 - 19.5)/SD
SD = (22.6 - 19.5)/0.84
= 3.69

The statement which describes this phenomenon is; Electrons flow freely into the magnetic field, causing the paper clips to move.
<h3>Metals and the Electromagnetic field</h3>
- Metals are made up of positively charged atoms of elements in which case the outermost orbital of these metal atoms contain electrons revolving round them.
On this note, upon interaction with the electromagnetic field posed by an electromagnet placed nearby, it follows that;
- The Valence electrons flow freely into the magnetic field created by the electromagnet and hence, causes the paperclip to move.
The complete question contains options given are;
Metal paper clips do not attract or repel each other. When an electromagnet is placed nearby, the paper clips can be observed to move toward it. Which statement describes this phenomenon?
- Paper clips turn into permanent magnets after exposure to a magnetic field.
- The electromagnet reacts to the strong force of attraction from paper clips.
- Electrons flow freely into the magnetic field, causing the paper clips to move.
- Magnetic domains within the paper clips align with the magnetic field.
