The data set represents the ages of students, in years, attending a robotics club meeting. What is the median age of the students in the club? 13, 15, 12, 12, 11, 16, 11, 13, 14, 12

12.5

Step-by-step explanation:

put them in order from least to greatest: 11, 11, 12, 12, 12, 13, 13, 14, 15, 16

the middle is 12 and 13 so you do 12+13 then divide by 2

to get 12.5

hope this helps

the expected value of the random variable : 0, 1 and 2

step-by-step explanation:

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
