Answer:
x = 40 when y = 10
Step-by-step explanation:
The reason that answer is true is because every time 'y' goes up by 1 'x' goes up by 4. So when 'y' = 10 that means x has to go up 10 times just like 'y' did.
Solution,
Arranging the data in ascending order:
0,1,1,2,2,3,3,4,4,4,4,4,4,4,5,6,6,7,8,9
N(total number of items)= 20
Now,
Median:
Again,
A
49y² - x² ← is a difference of squares and factors in general as
a² - b² = (a - b)(a + b) , then
49y² - x²
= (7y)² - x²
= (7y - x )(7y + x) → A
