Ted tossed a coin several times and recorded the number of heads and tails in the following table: Coin Experiment Side of Coin Number of Tosses Heads 18 Tails 22 What is the experimental probability of getting heads? 0.18 0.22 0.35 0.45

answer:

Correct answer is "D"0.45

Step-by-step explanation:

The results of the experiment are given as follows:

Coin Experiment Side of Coin Number of Tosses

                             Heads                           18

                              Tails                             22

This means that total 40 experiments were performed.

( Since 18+22=40)

Also, the number of times head turn up=18

Hence, the experimental probability of getting heads is:

Ratio of number of times head turn up to the total number of experiments performed.

Hence,

  Hence, the experimental probability of getting head is:

                                        0.45

*Hope this help

Have a nice day*

answer:

18 + 22 = 40 tries. 18 of those are heads so 18÷40=0.45

Step-by-step explanation:

the answer would be d.

step-by-step explanation:

move all variables to the left side and all constants to the right side

(x−3)^2+(y−1)^2=16

this is the form of a circle. use this form to determine the center and radius of the circle.

( x − h ) 2 + ( y − k ) 2 = r 2

match the values in this circle to those of the standard form. the variable   r   represents the radius of the circle,   h   represents the x-offset from the origin, and   k   represents the y-offset from origin.

r = 4

h = 3

k = 1

the center of the circle is found at   ( h , k ) .

center:   ( 3 , 1 )

these values represent the important values for graphing and analyzing a circle.

center:   ( 3 , 1 ).

radius:   4
