X + x + 2 + x + 4 = -213
3x + 6 = -213
3x = -219
x = -73
-73 + 2 = -71
-73 + 4 = -69
Solution: -73, -71, -69
Set up a proportion
90/x = 60/100
60x = 9000
x = 150
if you're wondering why I used 60 instead of 40 in the proportion it is because $90 is 60% of the original price, not 40%
hope this helps!
Answer:
x=4, y=-2
Step-by-step explanation:
Bao saved 179 dollars a
month
Ada saved 145 dollars more than Bao a month
Let B = Bao
let A = Ada
=> B = 179 dollars
=> A = b + 145 dollars or 179 + 145
Now, find the total amount will ada save in 3 years and half
=> 3 years and half = (12 x 3) + 6 = 42 months
=> A = 179 + 145 x 42
=> a = 324 x 42
=> A = 13 608 dollars in 3 years and half.
Answer:
1: because the lowest extreme and the numbers stayed the same, and if it doesn't go all the way down to the box q1, median, and q2 stay the same.
2: The median is 115, and the mean is 110.38 (etc) and that rounds down to 110, so yes
3: about 30% (I may be wrong)
4 Its less than the median. Median=9.5, mean=9.0 (Big difference)
You are correct (Below it)
5: no, because the highest extreme moved/shrinked, so if the Highest extreme moves down the mean moves down with it.
