Answer: the domain of the function in the table is 3<x>6 because with the coordinate points you gave, 3 is the lowest x value and 6 is the highest therfore x must be higher than 3 but lower than 6.
Step-by-step explanation:
Answer:
b
Step-by-step explanation:
We must determine the the x value at 90% confidence interval. We find this from a table relating confidence intervals and x values. For 90%, z is 1.645.
WE must determine the mean of 19 and 23:
We must determine the standard deviation. We let n be the number of population which is 2. We need to take the numbers 19 and 23 and subtract each by the mean and square the answer:
We then determine the mean of these two values as:
Now we take the square root of 365:
The standard deviation is 19.1
The answer is b
Presumably you mean 555 as a number in base 10.
We have
555 = 5 • (100 + 10 + 1)
… = 5 • (4 • 25 + 2 • 5 + 1)
… = 5 • (4 • 5² + 2 • 5¹ + 1 • 5⁰)
… = 4 • 5³ + 2 • 5² + 1 • 5¹
… = 4210₅
Answer: 12 apples would cost $2.28
Answer:
about 63.1%
Step-by-step explanation:
For the first song, it is certain it isn't a duplicate. For the second song, the probability that it is not a duplicate is 4999/5000. The probability the third song is not a duplicate is 4998/5000.
Hence the probability that none of the 100 songs is a duplicate is ...
5000!/4900!/5000^100 ≈ 0.369120
Then the probability that one or more is a duplicate is ...
1 - 0.369120 ≈ 0.630880
