Answer:
1. Order the values. 2. Find the median. 3. Find the lower quartile. 4. Find the upper quartile.
Step-by-step explanation:
Let m = minutes of commercial
30/90 = 8/m
Solve for m.
90(8) = 30m
720 = 30m
720/30 = m
24 = m
<h2>
Answer:</h2>
Option: A is the correct answer.
A. Two students are the same age but have different heights.
<h2>
Step-by-step explanation:</h2>
The height of a student could not be a function of the ages of a student because two or more students with the same age may have the different heights .
This means that a value on a x-axis (i.e. age) is mapped to two or more values i.e. corresponding y-value ( i.e. different heights) which violates the definition of function.
Hence, option: A is the correct answer.
Answer:
The maximum height that the ball will reach is 81 ft
Step-by-step explanation:
Note that the tray of the ball is given by the equation of a parabola of negative main coefficient. Then, the maximum value for a parabola is at its vertex.
For an equation of the form
So
the t coordinate of the vertice is:
In this case the equation is:
So
Therefore
Finally the maximum height that the ball will reach is
