This is simple!
To begin with, arrange all the numbers in order.
#1
5, 5, 20, 20, 25, 30, 35Mean: add all the numbers together and divide it by how many numbers are there
5+5+20+20+25+30+35=140
there are 7 numbers
Mean:
= 20
Median: The middle number, if the set of numbers have an odd number, then the one in between is the median, if there it is an even number, then the mean of the two in-between numbers is the median.
Median: 20
Mode: The most repeated numbers
Mode: 5 and 20
Range: Highest number - lowest number
Range: 35 - 5
30#2
Order: 44, 48, 48, 49, 59, 61, 63, 68Mean: 440 (sum of all numbers)
there are 8 numbers in total

=
55
Median: there are 8 numbers so, the mean of the in-between numbers will be the median
49+59=108
2 numbers

=
54
Mode: 48
Range = 68 - 44 = 24
Answer:
Yes.
(20-(-16)) = 20 + 16
20 + 16 = 36 thus
(20-(-16)) = 36
Step-by-step explanation:
With your equation, I'm pretty sure you are trying to determine whether or not this equation is true. Let's start with the first part.
(20-(-16))
Let's break it down.
20 - -16
Whenever a number is like that, it becomes a positive. (I don't really remember what its called, but it flips in negativity)
20 + 16
20 + 16 = 36.
36 = (20-(-16))
Answer: 92 and 94
Step-by-step explanation:
x = first number
x + 2 = second number
x + x + 2 = 186
simplify
2x + 2 = 186
subtract 2 from both sides
2x = 184
divide both sides by 2
x = 92
92 + 2 = 94
The numbers are 92 and 94.
10 and 7 are the correct answers!
