-- The trains start moving at the same time.
-- The space between them is initially 252.5 miles.
-- They reduce the distance between them at the rate of (124.7+253.5)=378.2mph.
-- It will take them (252.5 / 378.2) = 0.6676 hour to meet.
That's 40min 3.49sec .
-- After tooting and puffing toward each other for 8 minutes, they still have 32min 3.49sec to go before they meet each other. We're all hoping that they're on different tracks.
Answer:
Step-by-step explanation:
In this representation, the middle refers to the median, which is calculated by separating elements in equal parts and see which data results in the middle.
From the graph you can observe that number 13 has 6 elements on its right side and 5 elements on its left side, which is the most proximity to the middle of the group of data.
Therefore, the answer is 13, it's in the center.
Answer:
13
Step-by-step explanation:
i'm assuming 13 because when you divide the total to sides that's what you get but i'm not 100% sure
(you can choose multiple)
line
point
rotational
none
The figure has the following symmetry:
A. line
B. point.
In Mathematics and Geometry, the order of rotational symmetry of any geometrical figure can be defined as the number of times in which the geometrical figure can be rotated around a full (complete) circle and still look the same.
As a general rule in geometry, a geometrical figure with number of sides (n) has "n" lines of symmetry and its order of rotational symmetry is equal to "n."
Based on the above rule, we can reasonably infer and logically deduce that the figure has both line symmetry and point symmetry.
