Answer:
1.6
Step-by-step explanation:
So, first, write down the number of jokers in each deck of cards.
That would be: 0, 1, 2, 2, 3
Then, add up all those numbers.
0+1+2+2+3=8
Now, divide that sum by the number of decks or cards shown in the data set, which would be 5.
8/5=1.6
So, the mean of the data in the dot plot shown is 1.6.

Answer:
x (15 y + 6) is equivalent to 3x(2+5y)
Answer:
False
Step-by-step explanation:
It would have been right if the ratio was 15: 21 because 5*3:7*3= 15:21. You know that in ratio we can't interchange the numbers.
Answer:
1) $4400
2) $4400
Step-by-step explanation:
Let
X = price in first year
Y = price in 2nd year
Z = price in 3rd year
A = price in the end of 3rd year
Y = 1.1 X
Z = 0.8 Y
substitute Y into Z get Z = 0.88 X
A = 1.25 Z= 1.25(0.88X) = 1.1 X
1)
(125/100) Z = 22000
Z = 22000 x 100 / 125 = 17600
Z = 0.8Y
Y = Z/0.8 = 1.25Z
Amount of dollar decrease in 2nd year = Y - Z
= 1.25Z - Z = 0.25Z = 0.25 x 17600 = 4400 dollar
2)
Decrease in price over first 2 years = Increase in property in 3rd year - 2000
Hence, X - Z = (A-Z) - 2000
X - 0.8X = 1.1 X - 0.88 X - 2000
X - 0.88X - 1.1X + 088X = -2000
-0.1 X = -2000
0.1 X = 2000
X = 20000
Amount of dollar decrease during 2nd year = Y - Z = 1.1X - 0.88X = 0.22X
= (0.22) x (20000) = 4400 dollars
