This is simple!
To begin with, arrange all the numbers in order.
#1
5, 5, 20, 20, 25, 30, 35
Mean: 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: $\frac{140}{7}$ = 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, 68
Mean: 440 (sum of all numbers)
there are 8 numbers in total
$\frac{440}{8}$ = 55
Median: there are 8 numbers so, the mean of the in-between numbers will be the median
49+59=108
2 numbers
$\frac{108}{2}$ = 54
Mode: 48
Range = 68 - 44 = 24

Px + qx = r<br> solve for q

borishaifa [10]

Answer:

q = (r - px) / x

or you could write it as q = (r/x) - p

Step-by-step explanation:

px + qx = r

qx = r - px

q = (r - px) / x
