What is the median for the given set of data?

{40, 54, 22, 30, 55, 13, 33}
A) 32
B) 33
C) 40
D) 42

Step-by-step explanation:

Arranging in ascending order, we get

13 , 22 , 30 , 33 , 40 , 54 , 55

no of data (N) = 7

Now Position of Median

= {(N +1 ) / 2}th item

= {(7+1) / 2 } that item

= 4 that item

So now exact median = 33

step-by-step explanation:

f(x)=2x^2 -1 

translation is a function transformation that transform the function in a way of translating. by translating the function its graph is moved  up an down. moving the function f(x) 2 units to the left will be the new function g(x) with the equation: g(x)=f(x+2)=2(x+2)^2 -1

-2x + 7 = 7

subtract 7 from both sides.

-2x = 0

divide both sides by -2.

x = 0
