21+96 = 117
180-117=63
X= 63
There is one restriction: The number whose square root is needed can not be negative
Consecutive means they are right next to each other.
For example 6 and 7. 6+7 = 13
Or 8 and 9. 8+9=17
Hope that helps
Answer: 60 percent decrease
===========================================
Change in price = new - old = 100 - 250 = -150
The negative change means the price has gone down
Divide this change in price over the original 250 and convert to percent form
(change in price)/(original price) = -150/250 = -0.60
which converts to -60%
The negative percent change in price indicates a price decrease
So the price goes down by 60% meaning that it lost 60% of its value
Note how 60% of 250 is 0.60*250 = 150 which was the change in price computed earlier.
An outlier is a number much smaller or larger than the rest of the group of numbers. And outlier does not affect the median or the mode at all. It only affects the mean.
