Answer:

8x+12

Step-by-step explanation:

Remember that perimeter is all the sides combined. A rectangle has the same length and width for both sides.

P=2l+2w

P=2(4x-6)+2(12)

P=8x-12+24

P=8x+12

36 = 2(12) + 2(4x-6)
36 = 24 + 8x - 12
(take away 24 and add 12 to both sides)
24 = 8x
(divide both sides by 8)
3 = x

Answer: $1-(\frac{364}{365})^n$

Step-by-step explanation:

Binomial probability formula :-

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

We assume that the total number of days in a particular year are 365.

Then , the probability for each employee to have birthday on a certain day :

$p=\dfrac{1}{365}$

Given : The number of employee in the company = n

Then, the probability there is at least one day in a year when nobody has a birthday is given by :-

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

Hence, the probability there is at least one day in a year when nobody has a birthday = $1-(\frac{364}{365})^n$
