The two dinosaurs probably crossed paths at estimated coordinates (- 1, 2.5).
To find where the two equations actually intersect, set them equal to each other.
- 1/2x + 3 = 2x + 4
Subtract 4 from both sides, and add 1/2x to both sides to combine like terms.
2 1/2x = - 1 --> 5/2x = - 1
Multiply by 2/5 on both sides to isolate x
x = - 1(2/5)
x = - 2/5
Now plug in to either of the two equations. I used 2x + 4
- 1/2(- 2/5) + 3 = y
1/5 + 3 = y
y = 3 1/5
The actual coordinates where the dinosaurs crossed paths was (- 2/5, 3 and 1/5).
My original estimate was (- 1, 2 1/2) because based on the graph drawn above the point of interest (the intersection) appears to be below the third unit on the y-axis as well as in between the negative two unit and origin on the x-axis. My estimate was also off because the x-axis is counting by twos which does not necessarily allow for an accurate estimate strictly based on the naked eye.
1/2 = 50%
3/4 = 75%
So something in between that could be 2/3 (which equals 66.67% )
A few others could be: 3/5 ( equals to 60% ) , 7/10 ( equals 70%)
Hope that helps :)

Step-by-step explanation:
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.
