Hello everyone my name is Nevaeh, I know everyone needs help in some way, shape, or form and i am willing to provide. I set up a google classroom where people can ask me questions and get help on work. No question is a stupid question so do not be afraid to ask. I usually only focus on core subjects but if you ask i will help with other specialized subjects. I can do essays all the way to power points :)
My google classroom is Brainly help the code is 7hr2k4
Step-by-step explanation:
i dont know and understand your questions so i added the 2 fractions together
Answer Q=(9,-7). R=(9,-1). S=(5,-4)
Find the mean, median, mode, and range of this data: 49, 49, 54, 55, 52, 49, 55. If necessary, round to the nearest tenth.

The mean is the average.
So, to find the mean you want o add up all of the numbers and then divide by the number of numbers.
49 + 49 + 54 + 55 + 52 + 49 + 575 = 363
363 / 7 = 51.85
Rounded to 52
For the median you want o line all of your number up from least to greatest and then find the middle number.
49,49,49,52,54,55,55
Your median is 52
The mode is the number that is listed most often
49 is listed 3 times
54 is listed 1 time
52 is listed 1 time
55 is listed 2 times
So, your mode is 49
How many ordered pairs do you want? I'll just list 5 for you.
(0, -3)
(1, 9)
(2, 21)
(3, 33)
(4, 45)
With reciprocals, you flip the fraction to multiply and get 1
the recip is 9/7
