2. what is the external probability of rolling a 4 3 what is the external probability of getting at least one tail

2. 1- Experimental probability of rolling a 4 = 40%

3. 2- Theoretical probability is 3%  greater than experimental probability.

Step-by-step explanation:

Experimental probability of rolling a 4 = 100 ×

                                                                  = 100 × 0.4

                                                                  = 40%

Experimental probability of getting at least one tail  =

                                                                                    = 0.72

Theoretical probability of getting at least one tail  =

                                                                                  = 0.75

Theoretical probability is 3%  greater than experimental probability.

center (1,3) with radius 6

step-by-step explanation:

we must complete the square to find the center and radius of the circle.

first make sure the x and y squared terms have 1 as their coefficients. we also make sure x and y terms together.

we now create space between the x and y terms with parenthesis.

we complete the square by taking the middle terms -2x and the -6y - divide each and square them.

we add the squares to both sides.

simplify.

and write the quadratics in factored form.

the center is (h,k) or (1,3). the radius is the square root of 36 which is 6.
