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,

Hence, the experimental probability of getting head is:
0.45
Answer:
I do believe that the answer would be 56%
Step-by-step explanation:
Using estimation if the box is half full it would have 4.5 books in the box, if you add that extra book it would be around 56%
Answer:
33 dogs
Step-by-step explanation:
By taking the 22 cats and dividing it by the ratio. Then multiply that quotient by the ratio of dogs.
Thus:
22/2 = 11
11*3 = 33
There will be 33 dogs.
