Question: "A coin is tossed 8 times. Find the probability P(of exactly 6 occurrences of tails)"
Answer:
When we toss a coin we have 50% of probability to get a tail and 50% probability to get heads.
If we toss the coin 8 times, in order to find P(T=6), we need to use the binomial distribution:
where:
n = total number of events
k = number of successes we want
p = probability of success
Therefore:
<span>
</span>
= 28 · 0.015625 · 0.25
= 0.109375
Hence, the probability of getting 6 tails out of 8 tosses is D) 10.94%.
Answer:
B) 10x + 8y ≥ 210
Step-by-step explanation:
We know that we have to sit at least 210 people which means that we can fit more than 210, but no less than 210. This gives us a first step in solving since we know that the equation must be greater than or equal ( ≥) 210
This rules out C & D immediately.
Now we know that circular tables can sit 10 people and are represented by the variable x which means that each circular table will be equal to 10x and that rectangular tables are denoted by y and can sit 8 people making it recognizable by 8y. We know that the people sitting at all of the tables will be added up to give us a number of either 210 or more.
The only answer that gives us the tables and how many people they seat accurately is B since it is 10x and 8y. We also see that these two numbers are added together to make it greater than or equal to 210.
Answer:
3 m/s^2
Step-by-step explanation:
helpful formula below
a= (v - u)/t ....where v is the final velocity, u is the initial velocity, t is time elapsed
acceleration = (30 - 0)/10
= 3 m/s^2
