Take the average. The average of two numbers is halfway between them.
We have 0.333… = 1/3 and 0.444… = 4/9. Then the average of these is
(1/3 + 4/9)/2 = (3/9 + 4/9)/2 = (7/9)/2 = 7/18
To get another number between 1/3 and 4/9, take the average of one of these and 7/18. For instance,
(1/3 + 7/18)/2 = (6/18 + 7/18)/2 = (13/18)/2 = 13/36
Or more simply, just chop off some of the non-terminating part and increment the last digit. For example,
• chop 0.333… down to 0.33, then increase the last digit by 1 to get 0.34
• chop 0.444… down to 0.44, then decrease the last digit to get 0.43
Answer:
About 50.92
Step-by-step explanation:
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:
isosceles
Step-by-step explanation:
Two sides are the same length as indicated by the lines on the sides.
This tells use that the triangle is isosceles
B) 12 miles and 12 gallons. The answer is B because gallons and miles are 2 completely different types of measurement. If you look at A, C, D, they all have the same measurements. I hope this helped!
