Answer:
D. The data are discrete because the data can only take on specific values.
Step-by-step explanation:
<u>Continuous variables</u> are variables that can take on any value in an interval. Examples of continuous variables are length, time, etc.
<u>Discrete variables</u> on the other hand are variables that can only take on specific values.
The durations of movies in minutes<u> can only take on integer values from 0 to 60.</u> Therefore, it is a discrete data.
The correct option is D.
Answer:
-14
Step-by-step explanation:
-19=6k-4k+9
-19=2k+9
subtract 9 from both sides
-28=2k
-14=k
To check your answer plug 14 in for k
The domain and range of the given function are equal to (0, 3.85) and (0, 18.75) respectively.
<h3>How to calculate the domain of the function?</h3>
In this exercise, you're given the following function h(t) = -4.87t² + 18.75t. Next, we would equate the function to zero (0) to determine its domain as follows:
0= -4.87t² + 18.75t.
4.87t(-t + 3.85) = 0
t = 0 or t = 3.85.
Therefore, the domain is 0 ≤ t ≤ 3.85 or (0, 3.85).
<h3>How to calculate the range of the function?</h3>
h(t) = -4.87t² + 18.75t
h(t) = -4.87(t² - 3.85t + 3.85 - 3.85)
h(t) = -4.87(t - 1.925)² + 18.05
Therefore, the range is 0 ≤ h ≤ 18.05 or (0, 18.75).
