Percent decrease=(decrease)/(original) converted to percent
change=120 to 52
120-52=68
change or decrease=68
original=120
68/120=0.5666666=56.6666%
about 57%
So a-47=b
so total value =113 times 1,000,000=113,000,000=a+b
subtitute a-47=b into equation
a+a-47=113,000,000
add 47 to both sides
2a=113,000,047
divide both sides by 2
$56,500,023.5=a or <u>roughly</u> 56.5 million
a-47=b
56,500,032.5-47=b
56,499,976.5=b
so 56,500,023.5=a
56,499,976.5=b
It's 130, any quadrilateral's angles add up to 360 and those numbers add up to 230, 360-230 = 130

Answer:
3
Step-by-step explanation:
Given the data :
2, 3, 7, 8, 9, 13
2 5
3 4
7 0
8 1
9 2
13 6
The mean, = Σx / n ; n = sample size
Mean = 42 / 6 = 7
The mean absolute deviation = Σ|x - mean| / n
The mean absolute deviation is Hence,
(5 + 4 + 0 + 1 + 2 + 6) / 6
Mean absolute deviation = 18 / 6
Mean absolute deviation = 3
