Answer:
Mean = 51.4.
Mode = 49.
Median = 52.
Range = 6.
Step-by-step explanation:
Mean = Sum of all observations / Number of observations.
Mean = (49+49+54+55+52+49+52)/7
Mean = 360/7
Mean = 51.4 (to the nearest tenth).
Mode = The most repeated values = 49 (repeated 3 times).
Range = Largest Value - Smallest Value = 55 - 49 = 6.
Median = The central value of the data.
First, arrange the data in the ascending order: 49, 49, 49, 52, 54, 55, 55.
It can be seen that the middle value is 52. Therefore, median = 52!!!

<em>Comment on the example</em>
"Copy and paste" does not always work well on Brainly, especially when the characters being copied are not text characters. Many fractions get mangled in the process.
We suspect you intend ...
(1/3)/(4/7) = (1/3) ÷ (4/7)
In typeset form, this might be ...

___
Please note that the symbols "/" and "÷" and the word "over" are generally taken to mean exactly the same thing.* When math operations are involved in numerators or denominators, generally you need to enclose those numerators and denominators in parentheses.
1/3÷4/7 = 1/(3·4·7) = 1/84
(1/3)÷(4/7) = (1/3)·(7/4) = 7/12
___
* Some web sites treat them differently. Sometimes "÷" is taken to mean "the quantity everything that comes before the symbol '÷' divided by the quantity everything that comes after the symbol". Sometimes the word "over" is intended to mean the same thing. This usage for ÷ and "over" is non-standard, so it is best to use parentheses to clarify intent.
Uh, so, you're median is 81 already.
Since the middle two numbers are 82 and 80, you have to add them together and then divide by 2.
However, if you're trying to add a number in, adding 81 as it is would work as well.
Hope this helps!
