Explanation:
in order to allow a customer to select one or more option, the option to use is JCheckBox. Checkbox allows a user to chose more than one option from a list of option displayed. They are mostly presented in the form of a box which can be checked or unchecked. it allows a user to select more than a single option compare to radio button which allows a user to select just a single option from a list. So since the hair styling shop wants the user to select more than one option, The JCheckbox will be the right option. Further more, jLabel is just used to describe the purpose of the JCheckbox, like the name given to the checkbox.
Answer:
x = 29:73;
x_even = x(2:2:end);
Explanation:
In order to create a vector in Matlab you can use colon notation:
x = j:k
where <em>j</em> is 29 and <em>k</em> is 73 in your case:
x = 29:73
Then you can extract the even numbers by extracting the numbers with even index (2,4,6,etc.) of your vector:
x_even = x(2:2:end);
In the line of code above, we define <em>x_even</em> as all the elements of x with even index from index 2 till the end index of your vector, and an increment of 2 in the index: 2,4,6,etc.
If you want the odd numbers, just use the odd indices of your vector:
x_odd = x(1:2:end);
where <em>x_odd</em> contains all the elements of <em>x</em> with odd index from index 1 till the end index, and an increment of 2: 1,3,5,etc.
Answer:
Mobile Internet is dependant on cellular signal. Many countries, e.g. in Africa, don't have any coverage at all. Furthermore, mobile data might also not be available in the mountains as there are no cell towers and the rough terrain usually either blocks the signal entirely or weakens it significantly.
