Robert is playing darts. So far, he has hit the bullseye 4 times and missed the bullseye 12 times. Considering this data, how many bullseyes would you expect Robert to get during his next 20 tosses?

5

Step-by-step explanation:

So the ratio between the bulls eye and not the bulls eye is 4:12

Simplify that:

1:3=4

?:?=20

20/4=5

5 times 1 is 5. So he will get 5 bulls eye in 20 tosses

256π units²   (answer b)

step-by-step explanation:

the formula for the surface area of a sphere of radius r

is             a = 4πr²

and so, if r = 8 units, then the surface area is:

a = 4π(8 units)² = 256π units²   (answer b)

where are the choices?
