There are no solutions. The slopes of both lines are the same so they are parallel: they will never intersect. Therefore, there cannot be a solution.

Ted tossed a coin several times and recorded the number of heads and tails in the following table:

sineoko [7]

<h2>Answer:</h2>

Option: D is the correct answer.

D. 0.45

<h2>Step-by-step explanation:</h2>

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,

$Probability=\dfrac{18}{40}\\\\\\Probability=0.45$

Hence, the experimental probability of getting head is:

0.45
