Answer:
Explanation:
One group of students did an experiment to study the movement of ocean water. The steps of the experiment are listed below.
Fill a rectangular baking glass dish with water.
Place a plastic bag with ice in the water near the left edge of the dish.
Place a lighted lamp near the left edge of the dish so that its light falls directly on the plastic bag.
Put a few drops of ink in the water.
The student did not observe any circulation of ink in the water as expected because the experiment had a flaw. Which of these statements best describes the flaw in the experiment? (2 points)
Not enough ink was added.
Not enough water was taken.
The dish was too small for the experiment.
The lamp and the ice bag were at the same place.
The registers are used to temporarily hold small units of data and instructions .<span />

Explanation:
There are five methods written to solve all the problems stated in the question.
Method 1 : displayValue (Line 15 - 21)
This is the method that take one input array and use the print() method to display the all the elements in the array.
Method 2: reverseDisplay (Line 23 - 26)
This method will take one input array and print the value in the reverse order. We just need to start with the last index when running the for-loop to print the value.
Method 3: displaySum (Line 31 - 37)
This method will take one input array and use a for-loop to calculate the total of the values in the array.
Method 4: displayLess (Line 39 - 47)
This method will take one two inputs, a array and a limit. We use the limit as the condition to check if any value less than the limit, then the value will only be printed.
Method 5: displayHighAvg (Line 50 - 64)
This method will take one input array and calculate the average. The average will be used to check if any element in the array higher than it, then the value will only be printed.
Method 6: displayBoth (Line 66 - 75)
This method will take two input arrays and compare both of them to find out if any value appears in both input arrays and print it out.
Answer:
The expression on line 9 required 2 brackets
Explanation:
Given
The attached code
Required
Why syntax error.
The error points to line 10, but the error is actually from line 9
To get an integer input, the syntax is:
variable-name = int(input("Prompt"))
From the attached code, the line 9 is:
amount = int(input("Enter cheese order weight: ")
By comparing the syntax to the actual code on line 9, only 1 of the brackets is closed.
<em>This, in Python 3 is a sytax error</em>
