Karonlina flips a coin 60 times. how many times would you expect it's to land heads up?

We expect 30 heads.

Step-by-step explanation:

There are 2 sides  to a coin, heads and tails.  They are equally likely.  So the probably of getting a heads is 1/2

If we want to know how many times we will get heads, we multiply the number of flips by the probability of getting heads.

number of heads = 60 * 1/2

                              = 30

560

hope this : )

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.
