Answer:
A
Step-by-step explanation:
The number is decreased by 23 which means 23 is subtracted from the number.
let the number be x, then
x - 23 = 44 ( add 23 to both sides )
x = 67
The number is 67
Answer:
19.714
Step-by-step explanation:
Given :
Yearly Tuition Frequency
12-16 5
17-21 4
22-26 3
27-31 2
We calculate the midpoint (x) = (lower + upper) / 2
The mean yearly tuition :
The midpoint (x) :
X ___ F ___ Fx
14 __ 5
19 __ 4
24 __ 3
29 __ 2
The mean = Σfx / Σf
Σfx / Σf = (14*5 + 19*4 + 24*3 + 29*2) / (5+4+3+2)
Mean = 276 / 14
Mean yearly tuition = 19.714
Yes it is because -7+7=0 & 0+5=5 & 7+5=12
I would say D. I counted them and got 17 full squares and added the half’s.
You cannot tell which number is greater because you don't know how many numbers follow after 8 or 3. It all depends on how many numbers follow afterwards.
Example:
It could be 800 or 80,000
It could be 30,000 or 300,000
