For this case we have the following factorized expression:

$(2y-9) (2y-9)$

Applying distributive property we have:

$(2y) (2y) - (2y) (9) - (9) (2y) + (9) (9) =\\4y ^ 2-18y-18y + 81 =$

We add similar terms taking into account that: Equal signs are added and the same sign is placed.

$4y ^ 2-36y + 81$

ANswer:

$4y ^ 2-36y + 81$

-7/15.
You multiply the numerator and denominator to get -21/45. To simplify, divide each by the greatest common factor, which is three, to get -7/15.

A 10 bit string is to be randomly picked from all possible 10 bit strings. What is the probability that you picked a string with

allochka39001 [22]

Answer: 0.9990

Step-by-step explanation:

Given : The number of bits in a string = 10

The value taken by a bit is either 0 or 1.

Therefore, the probability that the bit is zero = $\dfrac{1}{2}=0.5$

Binomial probability distribution formula :-

$P(x)=^nC_xp^x(1-p)^{n-x}$ , where P(x) is the probability of getting success in x trials , n is the total number of success and p is the probability of getting success in each trial.

Now, the probability that you picked a string with at least one zero is given by :-

$P(x\geq1)=1-P(z$

Hence, the probability that you picked a string with at least one zero = 0.9990
