Answer:
The SQL queries are as follows:
1. select * from customer
select * from sale
select * from product
2. select name, sex from customer
3. select * from customer where sex = 'male'
4. select name, age from customer where sex = 'male'
5. select name, price, color from product
Explanation:
Given
Tables: customer, sale, product
Required
Answer question 1 to 5
(1) All data in the given tables
To do this, we make use of the select clause to retrieve data from each of the table and * to select all data.
So, we have:
select * from customer --> This lists all data from customer table
select * from sale --> This lists all data from sale table
select * from product --> This lists all data from product table
(2) Selected details from customer table
In (1), we have:
select * from customer --> This lists all data from customer table
To retrieve selected details, we replace * with the field names.
So, we have:
select name, sex from customer
(3) Male customers
In (1), we have:
select * from customer --> This lists all data from customer table
To retrieve male customers, we introduce the where clause
So, we have:
select * from customer where sex = 'male'
(4) Name and age of male customers
In (3), we have:
select * from customer where sex = 'male'
To retrieve the name and age, we replace * with name and age. So, we have:
select name, age from customer where sex = 'male'
(5) Name, price and color of products
In (1), we have:
select * from product --> This lists all data from product table
To retrieve selected details, we replace * with the field names.
So, we have:
select name, price, color from product

Wanda is taking photos using a lens that sees and records a very narrow view with a focal length longer than 60mm. When her friend asks what type of lens she is using for their photography outing,
Answer:
a telephoto lensExplanation: It's on Quizlet lolAnd I got it correct on the test...
It provides an instant 2x optical zoom and has a focal length that is twice that of the primary lens. Additionally, it has a limited field of view, which causes distant things to resemble those that are nearby.
What role of telephoto lens in taking photos?Simply put, a telephoto lens deceives the eye into thinking a topic is closer than it actually is. This may be the best option for photographers who are physically unable to go close to their subjects or who are concerned for their safety.
With a telephoto lens, the background elements appear larger and nearer to the foreground elements. The converse is true with wide-angle lenses, which make background elements appear smaller and farther away from the camera.
Therefore, a telephoto lens Wanda uses a lens longer than 60 mm in focal length to capture images with a very small field of view. When her friend inquires about the lens she will be using on their photographic excursion.

to achieve the desired functionality, between which 2 points would your finger contacts need to be made? hint: think of your fingers as being resistors.
Generally speaking, you would need to make contact between two sites with different electrical potentials in order to form a circuit if your fingers were acting as resistors.
How can I determine the difference in current and potential across each resistor?According to Ohm's law, the potential difference across a resistor with a constant resistance value is equal to the resistance multiplied by the current flowing through it.
How much resistance do two resistors coupled in series and parallel make up overall?You add up the individual resistances to determine the total overall resistance of several resistors connected in this manner. The following equation is used to accomplish this: R total = R1 + R2 + R3 and so forth.

Answer:
the complete body of source code for a given software program or application.
Explanation:
Caden, Jacob, Lucas, and Michael, whose last names are Armstrong, Boothe, Gardner, and Robinson, live in four houses in a row.
From the clues below, find each person’s full name and house position (with house number 1 at the left).
1. Michael doesn’t live next door to Lucas.
2. Robinson’s house is after Gardner’s and before Michael’s.
3. Boothe’s house is just before Armstrong’s.
4. Lucas’ house, which is not first, is somewhere to the left of Caden’s.
Answer:
Jacob Gardner - Lucas Robinson - Caden Boothe - Michael Armstrong
Explanation:
According to clue 4, Lucas's house is not the first, and he has a house on his right, so it can only be house 2 or house 3. Therefore, Caden's house (which is on the right right of Lucas's), it can only be house 3 or house 4.
In turn, track 1 says that Michael's house is not next to Lucas's, so it can be 1 (if Lucas's house is 3) or 4 (if Lucas's house is in 2).
Track 2 says that there is a house before Michael's, which eliminates the possibility that Michael's house is number 1 (there would be no previous house). Thus, in addition, Lucas's house turns out to be 2 (Michael's house is not next door) and Caden's is 3, while Jacon's is house 1.
Jacob - Lucas - Caden - Michael
In turn, regarding surnames, clue 2 says that Robinson's house is after Gardner's and before Michael's. Thus, Robinson can be the last name of Jacob or Lucas, and Gardner that of Lucas or Caden. Now, since Boothe's house is just before Armstrong's, the order would be as follows:
Jacob Gardner - Lucas Robinson - Caden Boothe - Michael Armstrong
What do you understand by ISA? Does the external auditor follow
ISA or any regulatory body in conducting their audit? (150
words)
ISA stands for International Standards on Auditing. These standards are a set of globally recognized audit guidelines developed by the International Auditing and Assurance Standards Board (IAASB).
These standards aid in the achievement of international consistency and quality in auditing practices and provide for an objective methodology that auditors can use to measure the effectiveness of the audit process. It is relevant for both internal and external auditing.Internal auditors are in charge of verifying a company's accounts, processes, and systems. An internal auditor's function is to ensure that a company's financial data is correct, secure, and that all procedures are followed. Internal auditors should be familiar with ISA and use it to help guide their work.External auditors, on the other hand, are auditors who are not employed by the company they are auditing. External auditors must follow all ISA principles and guidelines to perform a fair and objective audit of a company's financial statements. External auditors are obliged to follow the auditing regulations and procedures of any regulatory body in addition to following ISA guidelines, as the auditing process is overseen by a number of regulatory bodies.In conclusion, the ISA provides guidelines that both internal and external auditors must follow. External auditors are required to comply with all ISA principles, regulations, and procedures in addition to the auditing guidelines of regulatory bodies.

make_codes_helper() is a recursive function that takes a tree node, codes, and current_code as inputs. current_code is a str object that records the code for the current node (which can be an internal node). The function needs be called on the left child and right child nodes recursively. For the left child call, current_code needs increment by appending a "0", because this is what the left branch means; and append an "1" for the right child call.
