What else can I help you with?
When you need to satisfy two or more criteria to initiate an event in a program you must make sure that the second decision is made entirely independently of the first decision?
Evaluate the criteria before executing the conditional expression. In pseudocode:result1 = evaluate( criteria1 );result2 = evaluate( criteria2 );if( result1 && result2 ) initiate_event;Note that this is not the same as the following:if( evaluate( criteria1 ) && evaluate( criteria2 )) initiate_event;If the evaluation of criteria1 fails for any reason, then the whole expression fails and criteria2 is never evaluated. so if the evaluations must be done independently of each other, then they must be done prior to the conditional expression, storing the results for use in the conditional expression.
How do you choose multiple if statement and switch statement?
If you must evaluate two or more expressions separately, use multiple if statements. If you only need to test all the possible evaluations of a single expression, use a switch.
How many times will a for loop be executed?
As many times as necessary. There is no practical limit because all loops rely on a control expression that can only evaluate true or false. So long as the control expression evaluates true, the loop will just keep iterating. The canonical example is the infinite loop: while (true) { // ... } The control expression never evaluates false, so the only way to break out of this loop is from within the body of the loop itself. Although we typically use infinite loops when the control expressions are far too complex to be expressed as a simple expression in the while statement, we can easily avoid this by placing those control expressions in a function. For example, if the control expressions depend on three variables, a, b, c, we can pass those variables to a predicate function that returns true or false: while (evaluate (a, b, c)); Here, the overall complexity of the control expression is hidden within the evaluate function, greatly simplifying the calling code.
Only scientist use models?
no!
How is the precedence of operators in an expression overridden in most languages?
Precedence of operators in an expression overridden by the use of parentheses
Can you use the power law of exponents to evaluate an expression?
Yes, if appropriate.
How can you use models to compare expressions?
what the heck
Why do you use models when you study earth?
To compare it.
Why are multiplication division addition and subtraction used in evaluating expressions?
If they are present in the expression you need to use them to evaluate the expression, if they are not, you don't. You would not use any of them - at least not explicitly - to evaluate sqrt[ln(pi)], for example.
Which property wouldvu use yo evaluate the expression 29 plus 33 plus 7?
Addition
use mental math to evaluate the expression 6(31)+6(4)-6(15)?

How can I evaluate the expression 16 plus 14 plus 9?
Use a calculator, or just the addition techniques taught to you in 1st grade.
How do I use the IF function?
The IF function takes three parameters. The first is an expression, such as an inequality, that will evaluate to either true or false. If the expression is true the second parameter is used, otherwise the third parameter is used.
How do generic MP3 players compare to the different models of ipods?
Generic models of MP3 players are very comparable to iPod models. iPod models use apple software like iTunes as well as have the capability of apps and games on models like the iPod touch.
Explain how to write and evaluate an algebraic expression.thirteen less than the quotient of forty and a number; evaluate when n = 2?
Sample Response: Replace keywords with variables, numbers, and operations. Less than is subtraction, and the quotient is division. Order matters with subtraction and division. The expression is 40 n -13. To evaluate is the expression, substitute 2 in for the variable, and then use order of operations to simplify. The value when n = 2 is 7.
Explain how to write and evaluate an algebraic expression.one more than the product of a number and seven, decreased by five; evaluate when n = 6?
Sample Response: Replace key words with variables, numbers, and operations. More than is addition, product is multiplication, and decreased by is subtraction. The constants are 1, 7, and 5. The expression is 1 + 7n – 5. To evaluate the expression, substitute 6 in for the variable, and then use order of operations to simplify. The value when n = 6 is 38.
