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?
a. 0.18
b. 0.22
c. 0.35
d. 0.45

Option: D is the correct answer.

                     D.  0.45

The results of the experiment are given as follows:

Coin Experiment Side of CoinNumber 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

9.55 degrees.

step-by-step explanation:

the given angle is

1 cycle is equal to 2π radians. so 4π will be equal to two cycles.

5.166667π-4π = 1.166667π

hence, this angle goes a little more than negative x axis.

1.166667π-π= 0.166667π

hence, the reference angle is 0.166667π radians.

1 radian = 57.2958 degrees

now, in degrees, this should be equals to 9.55 degrees.

answer: 5100 just subtract
