Simplify the fractions, and then you can easily see the answer.
Answer:
0.71
Step-by-step explanation:
When a coin is tossed 100 times, it yields heads 71 times and tails 29 times.
So the probability of heads = Number of heads/Total number of tosses
= ![\[\frac{71}{100}\]](https://tex.z-dn.net/?f=%5C%5B%5Cfrac%7B71%7D%7B100%7D%5C%5D)
= ![\[0.71\]](https://tex.z-dn.net/?f=%5C%5B0.71%5C%5D)
Similarly, probability of tails = Number of tails/Total number of tosses
= ![\[\frac{29}{100}\]](https://tex.z-dn.net/?f=%5C%5B%5Cfrac%7B29%7D%7B100%7D%5C%5D)
= ![\[0.29\]](https://tex.z-dn.net/?f=%5C%5B0.29%5C%5D)
So the probability that the next flip results in a head = Probability of heads in the toss = 0.71

Answer:
14
Step-by-step explanation:
Use rise over run, (y2 - y1) / (x2 - x1)
Plug in the points:
(y2 - y1) / (x2 - x1)
(8 + 20) / (5 - 3)
28 / 2
= 14
So, the slope is 14.
