Answer:
The data A, B, C and D are Qualitative.
The data remains qualitative even when inputed as 1, 2, 3 and 4
Step-by-step explanation:
The data consisting of A, B, C and D is Qualitative , reason being that they can only be classified into categories.
Also, when the data is inputed as 1, 2, 3 and 4; the data remains Qualitative because theycannotbemeaningfully addd , subtracted, multiplied or divided.
After 5 tests, her average was 88. To have a seven-test average of 90, the total must be:

Her average after 5 tests was 88. Her total score on the 5 tests is:

Subtract:

Find the average by dividing by 2:

Her average must be 95
The ball will hit the ground at 0.125 seconds
<h3>
Quadratic function</h3>
The equation of the function is a quadratic function, and the function is given as:

When the ball hits the ground, the value of h is 0.
So, the equation of the function becomes

Subtract 2t from both sides of the equation

Divide both sides by -2t

Divide both sides by 8

Hence, the ball will hit the ground at 0.125 seconds

The function is y=2x
this means that the solutions will have the form (x, y)=(x,2x).
For example: (0,0),(1,2),(2,4),(3,6) are solutions.
The first answer choice satisfies the above conditions.
The second answer choice contains (2,2), and (2,6), both of which do not satisfy the (x,2x) condition, so it's not correct.
The third answer choice contains (4,2), which again does not satisfy (x,2x), so not the right answer.
