The two variables that we should use are:
- x = number of minutes that the call lasted.
- y = cost of that call.
<h3>
What variables should we use?</h3>
Here we want to study a relation between the cost per call as the function of the minutes that the call lasted.
So, we need to use two variables, x will be the number of minutes that call lasted, this is the independent variable.
And the variable that depends on that should be the cost of the call, let's say, y is the cost of the call.
These are the two variables that we need to model the situation:
y = f(x)
There says:
<em>"The cost of the call is a </em><em>function </em><em>of the number of minutes that the call lasted".</em>

Get rid of distractions that makes you procrastinate.
Step-by-step explanation:
Focus doing your practices. To focus, you need to get rid of any distractions that make you procrastinate.

This is just my suggestion. It works for some people.
Answer:
Option C is right
C. They are independent because, based on the probability, the first ace was replaced before drawing the second ace.
Step-by-step explanation:
Given that the probability of drawing two aces from a standard deck is 0.0059
If first card is drawn and replaced then this probability would change. By making draws with replacement we make each event independent of the other
Drawing ace in I draw has probability equal to 4/52, when we replace the I card again drawing age has probability equal to same 4/52
So if the two draws are defined as event A and event B, the events are independent
C. They are independent because, based on the probability, the first ace was replaced before drawing the second ace.
Answer:
Step-by-step explanation:
$ 86,000 lies in the category $84201 - $ 160725
Tax = 14,382.50+ 24% of the amount over $84,200
Amount over $84,200= 86,000 - 84,200 = $1,800
Tax for the amount $ 1,800 =24% * 1800 = 0.24 * 1800
= $ 432
Tax for the amount $86,000 = 14382.50 + 432
=$ 14814.50
