X+8=-2<br><br> O A. x= 10<br> OB. x=-6<br> O C. x=6<br> OD. x= -10

MaRussiya [10]

Answer: option D

Step-by-step explanation:

X+8=-2

x= -2-8 (you should make x the subject so you switch the +8 to the other

x= -10 side which becomes -8)

so you get -10 because, if both the numbers have the minus sign then you should add the two values which will be a negative answer. So your answer is option D

A company with n employees publishes an internal calendar, where each day lists the employees having a birthday that day. What i

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