Answer:
-4
Step-by-step explanation:
That's the Kolakovski sequence,
Well, if you say it's A... But that does make sense. Using the triangle inequality theorem, there is only one triangle you can make from that.
Answer: 0.8588
Step-by-step explanation:
Assume a binomial probability distribution with n = 40 and (symbol looks like a pie sign) = 0.55.
Compute the following: (Round the value for standard deviation and intermediate calculations to 2 decimal places and your final answer to 4 decimal places.)
The mean and standard deviation of the random variable.
mean = np = 40*0.55 = 22
std = sqrt(npq) = sqrt(22*0.45) = 3.1464
--------------------------------------------------
The probability that X is 25 or greater.
P(25<= x <= 40) = 1 - binomcdf(40,0.55,24) = 0.2142
------------------------------------------------------
The probability that X is between 15 and 25, inclusive.
P(15<= x <=25) = binomcdf(40,0.55,25)-binomcdf(40,0.55,14) = 0.8588
Answer:
679
Step-by-step explanation:
The goal of this exercise is to find a three digit number given five statements.
1 - We can conclude that two digits out of 964 are correct but in the wrong place.
2 - One digit out of 147 is correct, but in the wrong place
3 - One digit out of 189 is correct and in the right place. Since 1 is on the same place in 147 and 189, 1 is not the correct digit. The correct digit is either 8 or 9.
4 - One digit out of 286 is correct, but in the wrong place. Since 8 is on the same place in 189 and 286, 8 is not the correct digit. We can then conclude that 9 is correct (statement 3) and in the right place (third) and that either 2 or 6 are correct but in the wrong place.
5 - 523 are all wrong. We can then conclude that 6 is correct and that is not in the third or second place, which leaves it in the first place.
If 1 and 4 are incorrect, from the second statement, we infer that 7 is the remaining correct digit at the second place.
Therefore the number is 679
