Answer:
-2.5
Step-by-step explanation:
-30 + (-15) + (-20) + 55 = -10. Then you divide it by how many numbers there are (4). Which equals - 2.5. If this is wrong, then round up to -3.
The next three terms are: 1/6 , 0 and -1/6
Step-by-step explanation:
Given sequence is:
First of all, we have to find the common difference
The common difference is -1/6
We can simply add -1/6 to the previous term to find the next terms so,
Adding -1/6 to 1/3
Hence,
The next three terms are: 1/6 , 0 and -1/6

Answer:
Step-by-step explanation:
experimental probability is the probability of an event occuring when we perform an experiment.
It goes according to the results of the experiment, not the theory behind it.
<u>Probability of landing tails up, therefore, is the number of times it came tails up divided by the total number of times the coin was flipped.</u>

Hence
P (tails) = 36/80 = 9/20
