Answer:
[tex](3.7 * 10^{-2}) (1.2 * 10^3) = 44.4[/tex]
Explanation:
Given
[tex](3.7 * 10^{-2}) (1.2 * 10^3)[/tex]
Required
Evaluate
[tex](3.7 * 10^{-2}) (1.2 * 10^3)[/tex]
Remove bracket
[tex](3.7 * 10^{-2}) (1.2 * 10^3) = 3.7 * 10^{-2}*1.2 * 10^3[/tex]
Rewrite as:
[tex](3.7 * 10^{-2}) (1.2 * 10^3) = 3.7 *1.2* 10^{-2} * 10^3[/tex]
[tex](3.7 * 10^{-2}) (1.2 * 10^3) = 4.44* 10^{-2} * 10^3[/tex]
Apply law of indices
[tex](3.7 * 10^{-2}) (1.2 * 10^3) = 4.44* 10^{-2+3}[/tex]
[tex](3.7 * 10^{-2}) (1.2 * 10^3) = 4.44* 10^1[/tex]
[tex](3.7 * 10^{-2}) (1.2 * 10^3) = 4.44* 10[/tex]
[tex](3.7 * 10^{-2}) (1.2 * 10^3) = 44.4[/tex]

Define the followimg terms as it relates to coding.
Expression
Variable
Assignment operator
Answer and Explanation:
In coding, an expression is used to represent values. It may contain variables and/or constant.
Examples of expressions are:
[tex]a - b[/tex] [tex]a * 2[/tex] [tex]4 - 3[/tex]
Variables are literally memory locations. They are used to storing values, and they assume the values they store during program execution.
At any point in the program, the value of the variable can be changed.
Lastly, there are guidelines that follow naming variables (depending on the programming language).
Examples of accepted variable names (in C++) are:
num, num_1, num1
Assignment operator
This is the = sign. It is used for assigning values to variables.
Examples of how it is used are:
[tex]num1 = a - b[/tex]
[tex]num\_1 = a*2[/tex]
[tex]num = 4 - 3[/tex]
The following is a wrong usage of the operator
[tex]4 - 3 = num[/tex]
A programmer for a weather website needs to display the proportion of days with freezing temperatures in a given month.
Their algorithm will operate on a list of temperatures for each day in the month. It must keep track of how many temperatures are below or equal to 32. Once it's done processing the list, it must display the ratio of freezing days over total days.
Which of these correctly expresses that algorithm in pseudocode?
A.
numFreezing ← 0
numDays ← 0
FOR EACH temp IN temps {
IF (temp ≤ 32) {
numFreezing ← numFreezing + 1
}
numDays ← numDays + 1
DISPLAY(numFreezing/numDays)
}
B.
numFreezing ← 0
numDays ← 0
FOR EACH temp IN temps {
IF (temp ≤ 32) {
numFreezing ← numFreezing + 1
}
numDays ← numDays + 1
}
DISPLAY(numFreezing/numDays)
C.
numFreezing ← 0
numDays ← 0
FOR EACH temp IN temps {
IF (temp < 32) {
numFreezing ← numFreezing + 1
}
numDays ← numDays + 1
}
DISPLAY(numFreezing/numDays)
D.
numFreezing ← 0
numDays ← 0
FOR EACH temp IN temps {
IF (temp ≤ 32) {
numFreezing ← numFreezing + 1
numDays ← numDays + 1
}
}
DISPLAY(numFreezing/numDays)
Answer:
B.
Explanation:
The correct Pseudocode for this scenario would be B. This code makes two variables for the number of total days (numDays) and number of freezing days (numFreezing). Then it loops through the entire data set and checks if each temp is less than or equal to 32 degrees. If it is, it adds it to numFreezing, if it is not then it skips this step, but still adds 1 to the total number of days after each loop. Once the entire loop is done it prints out the ratio, unlike answer A which prints out the ratio for every iteration of the loop.
numFreezing ← 0
numDays ← 0
FOR EACH temp IN temps {
IF (temp ≤ 32) {
numFreezing ← numFreezing + 1
}
numDays ← numDays + 1
}
DISPLAY(numFreezing/numDays)

Please help!! I dont need the answer i just need explaining on how to do this!!!!
Explanation:
There are only two inputs to the circuit, and one output. There is an internal signal, not an input, between the inverter and the AND gate.
Here, it is convenient to label the top input A, the inverter output B, and the bottom input C. Of course, the output is labeled D.
Then B is the logical inverse of A, and D is the AND of B and C.

You are calculating commissions for sales staff at work. Employees receive ten dollars for every item sold. Your boss also wants to know the grand total paid to all employees as commission. How would you set this up in an Excel workbook and would you use absolute references, relative references, or both?
Answer:
To find the grand total paid to all employees as commission, we note the following;
The amount received by employees as commission for each item sold, r = $10.00
The information the boss wants to know = The grand total paid to all employees as commission
Let 'n' represent the the total sales, we have;
The grand total commission = Total sales × Commission
1) On MS Excel, four columns are created, labelled, Serial number, Employee Name, Number of Items Sold, Commission
2) In the second row, in the cell under the Commission column heading, Input the formula '=(Cell reference of adjacent Number of Items Sold) × 10' in the cell
3) Copy the the above formula to all the cells in the Commission column by clicking on the cell containing the formula, moving the mouse to the bottom right corner of the cell, and when the mouse pointer changes to a cross sign, left click and hold and drag to all the cells in the column
4) Input the formula =SUM(Argument) in the blank cell below the created Commission list
Where;
Argument = The reference to the range of cells containing the values in the Commission column
5) The output of the =SUM formula is the grand total paid to employees as commission
