Each of three friends flips a coin 85 times. The results for each friend are shown in the tables. Find the relative frequency for the event "heads" for each friend. If the friends combine their results to get
130 heads and 125 tails, what is the relative frequency for the event "heads"? Use pencil and paper.
Suppose each friend flips a coin 850 times. Is there a value you would expect the relative frequency
for the event "heads" to be close to?

step-by-step explanation:

a.

step-by-step explanation:

step 1 distribute 2 to every term in the parentheses

step 2 add 10 on both sides of the equal sign

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
