Any process to have heat transfer from a cooler to a hotter object as its sole result.
Answer:
a. alphabet line
Explanation:
Technical drawings are the drawings that help in communicating the designs. These designs are the designs that provide the instruction for the manufacturing of any object. The designs are made with the help of lines and line symbols. Line symbols are termed to be alphabet of lines. They help the designers to draw the designs with accuracy. Various lines are drawn that differ in terms of thickness and darkness. These variations helps the designers to mark the design accurately.
95.44% IQ scores are between 77 and 125
We're given,
Mean (a)=101
standard deviation (b)=12
To find : ![P[77 < x < 125]](https://tex.z-dn.net/?f=P%5B77%20%3C%20x%20%3C%20125%5D)
Using Empirical Rule:
∴ 
![P[\frac{77-101}{12} < \frac{x-a}{b} < \frac{125-101}{12}]\\](https://tex.z-dn.net/?f=P%5B%5Cfrac%7B77-101%7D%7B12%7D%20%3C%20%5Cfrac%7Bx-a%7D%7Bb%7D%20%3C%20%5Cfrac%7B125-101%7D%7B12%7D%5D%5C%5C)
![=P[-2 < z < 2]\\](https://tex.z-dn.net/?f=%3DP%5B-2%20%3C%20z%20%3C%202%5D%5C%5C)
![=P[Z < 2]-P[Z < -2]\\](https://tex.z-dn.net/?f=%3DP%5BZ%20%3C%202%5D-P%5BZ%20%3C%20-2%5D%5C%5C)
=95.44% (approx)

Answer:
See explanation
Explanation:
When an element tends to lose its valence electrons in chemical reactions, it behaves more like a metal.
When an element tends to gain valence electrons in chemical reactions, it behaves more like a nonmetal.
Metalloids have properties intermediate between those of pure metals and pure nonmetals. Usually, metalloids appear in groups where they are sandwiched between nonmetals and metals such as in groups 13, 14 and 15.
The combination that could be the total sales would be 360 tablets and 180 computers.
<h3>Total sales</h3>
Over 300 total sales were made in January
100 tablets and 20 computers were sold in February.
This means that total sales would be: (300+) 100 + 20 = 420+
Only options B and C have 420+ total sales.
But, there are more tablet sales than computers.
Thus, we are left with only option B
