Answer:
a) range check
Explanation:
Validation can be defined as an automatic computer check that is designed to ensure any data entered is sensible, consistent, feasible and reasonable.
Basically, there are five (5) main validation methods and these includes;
I. Presence check: checks that the user enters (inputs) data into the field. It ensures a field isn't accidentally left blank.
II. Length check: checks that the data entered isn't too short or too long. It ensures that the data meets the minimum characters.
III. Type check: checks that the data entered is in the right format. For example, string, integer, float, etc.
IV. Check digit: checks that the digit entered is acceptable and consistent with the rest of the digits.
V. Range check: checks that the data entered is between the accepted lower (minimum) and upper (maximum) level.
Hence, range check is a validation type you would use to check that numbers fell within a certain range.
For example, 0 < x > 1000 is a range check.
<em><u>Answer:</u></em>
x = -1/3
<em><u>Explanation:</u></em>
3^(x + 1) = 9^(2x + 1); So we should first make 9^(2x + 1) a power of 3 so:
3^(x + 1) = 3^2(2x + 1) <-- I replaced 9 with 3^2 so then we have to multiply 2 by 2x + 1
3^(x + 1) = 3^(4x + 2)
We can then just create the equation: x + 1 = 4x + 2 (because the 3^ doesn't matter and we just want them to be equal so yeah)
We then have to simplify:
x + 1 = 4x + 2
Subtract x from both sides:
1 = 3x + 2
Subtract 2 from both sides:
-1 = 3x
Divide 3 on both sides:
-1/3 = x
There ya go

Answer:
In the given scenario option B. Learnability is correct
Explanation:
Because user doesn't visit causally but only once or twice in this scene user must learn from design and interface instead of remember some steps So option B. Learnability is more suitable here. In other scenario where user visits site repeatedly then both are of equal importance is correct option.
I believe A is the answer here.
