40 PTS!!How many possible outcomes exist when four fair coins are flipped? 2 4 8 16

16

Step-by-step explanation:

4 coins 2 out comes each

2 X 2 X 2 X 2 = 16

2^4 = 16

Hope i helped you

option c) graph of line going through 1, 4 and 3, 10

step-by-step explanation:

let y equal to margo's coin collection

let x equal to number of years

at the begining x=0, y=1 → point=(x,y)→point=(0,1)

she adds 3 coins per year, then y=1+3x

at x=1, y=1+3(1)=1+3→y=4→point=(x,y)→point=(1,4)

at x=3, y=1+3(3)=1+9→y=10→point=(x,y)→point=(3,10)

the graph of line going through (1, 4) and (3, 10), then the option c is the correct.

the height of the surface increases from the center out to the sides of the road

it is c!
