Released in 1976, the Apple I was Apple Computer's first product. O True O False

Can you help me with these AP Computer Science Questions. (THIS IS DUE BY 1:30 PM today) you have to evaluate the Boolean Expres

vfiekz [6]

Answer + Explanation:

'and' -> both statements are 'True' to evaluate as 'True'.

'or' -> at least one statement is 'True' to evaluate as 'True'.

1. True (grade has the value of 82, so the statement evaluates to 'True').

2. True (Both statements are true, this expression evaluates to 'True').

3. False (Both statements are false, this expression evaluates to 'False').

4. True (the != operator means not equal. Since the 'name' variable holds the string 'Rumpelstiltskin', name != 'Rumpelstiltskin' evaluates to 'False'. The 'not' operator returns the opposite of the given Boolean expression, so this expression evaluates to 'True').

5. True (name == 'Rumpelstiltskin' evaluates to 'True', so this expression is true).

6. False (All statements evaluate to 'False').

7. True (All statements evaluate to 'True').

8. False (All statements evaluate to 'True' except for not(x == - 3) which evaluates to 'False', so the whole statement now becomes false).

9. True (grade+5 < 90 and grade >= 80 evaluates to 'True', so this whole expression becomes true).

10. True (grade > 0 and x % 2 == 1 evaluates to 'True')

Hope this helps :)

A programmer wrote the program below. The program uses a list of numbers called numList. The program is intended to display the

Nezavi [6.7K]

Answer:

The conclusion is incorrect; using the test case [0, 1, 4, 5] is not sufficient to conclude the program is correct.

Explanation:

From the code snippet given, we cannot conclude that the test case is sufficient.

One of the reasons is because the test case contains only integer variables.

Tests need to be carried out for other large and floating points numerical data types such as decimal, double, float, etc. except that when it's known that the inputs will be of type integer only else, we can't rush into any conclusion about the code snippet

Another reason is that input are not gotten at runtime. Input gotten from runtime environment makes the program flexible enough.

Lastly, the array length of the array in the code segment is limited to 4. Flexible length needs to be tested before we can arrive at a reasonable conclusion.

brilliants [131]

Answer:

The answer to the given question is the option "a".

Explanation:

In this question, the answer is "middleware" software because this software works between the operating system and the applications that provide connectivity to two or more software applications. for example database, application server, etc and other choices that are not correct can be described as:

In option b, The integration middle wear represents the software of the system. It does not coordinate between operating and application software.
In option c, It is used to manage the data and the information for the process.
In option d, It includes the hardware, software and the networks. In this hardware and software link for use software.

That's why the answer to this question is the option "a".
