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:
x=20
4=140
1=40
Step-by-step explanation:
7x=2×+100
5×=100
×=20
4=7(20)=140
1=180-140=40
Its a quarter because 2 dimes is 20 cent and 1 nickel is 5 cent so if we add them we get 25 cent which is a quarter.
