Answer:
mean=134.3
median=65.5
mode=60
Step-by-step explanation:
Mean is computing by adding the all data values and then divided by number of values
mean=sum of all values/number of values
There are 20 data values.
mean=(88+50+66+60+360+55+500+71+41+350+60+50+250+45+45+125+235+65+60+110)/20
mean=2686/20
mean=134.3
For calculating median we arrange the data in ascending order
41 45 45 50 50 55 60 60 60 65 66 71 88 110 125 235 250 350 360 500
n/2=20/2=10 is an integer
So, the median is the average of n/2 and (n/2)+1 value
The median is average of 10th and 11th value
median=(65+66)/2
median=65.5
Mode is the most repeated value and we see that number of times the values are repeated are
45= 2 times
50= 2 times
60= 3 times
Thus, the most repeated value is 60 and it is the mode of data.
Mode=60
Answer:
Let the number be x
so, x/4 = x-3
x = 4(x-3)
x= 4x-12
x-4x = -12
-3x = -12
x= 12/3
x = 4

Hello from MrBillDoesMath!
Answer:
"every pizza crust made requires 3/2 (1.5) "flours used""
Discussion:
The slope of a line is given by ( change in y)/(change in x). In our case
(change "flour used" )/ (change "pizza crusts made") = 3/2.
Multiply both sides by (change "pizza crusts made") to get
(change "flour used" = 3/2 (change "pizza crusts made")
In other words every pizza crust made requires 3/2 (1.5) "flours used"

9% is equivalent to 9 / 100 = 0.09 as a decimal fraction.
So the tax on $3,000 = 3000 * 0.09 = $270
