Answer: 0.4512
Step-by-step explanation:
A bit string is sequence of bits (it only contains 0 and 1).
We assume that the 0 and 1 area equally likely to any place.
i.e. P(0)= P(1)= 
The length of bits : n = 10
Let X = Number of getting ones.
Then , 
Binomial distribution formula :
, where p= probability of getting success in each event and q= probability of getting failure in each event.
Here , 
Then ,The probability that a bit string of length 10 contains exactly 4 or 5 ones.






Hence, the probability that a bit string of length 10 contains exactly 4 or 5 ones is 0.4512.
Answer:
Combine like terms, although the provided answer is missing a "-" sign in front of the "13."
Step-by-step explanation:
Combine like terms. The -7 and -6 can be added to produce -13.
The correct result is <u>-</u>13 - 2x^2 = <u>-</u>2x^2 + 1 [Not _13- 2x² = _2x² + 1
Perhpas the initial equation is written incorrectly(?)
Answer:
B) 0=(2x+3)(x-1)
Step-by-step explanation:
factor the equation f(x) = 2x² + x - 3
=> f(x) = (2x + 3)(x - 1)
Helppppppp PLEASE !! I appreciate it
The awnser would be 30.
