Answer:
Step-by-step explanation:
Here is a tip: When you have something that looks like this - ( - , turn it into a plus sign. It looks kind of like a plus sign anyway. So if you have 53- (-32), turn it into 53 + 32. Does that make sense?
So 53 + 32 = 85.
Another tip to do it in your head, is to do 50 + 30 = 80, then do 3 + 2 = 5, and add them. It's easier than trying to juggle the odd numbers. :)
Answer: 
Step-by-step explanation:
Binomial probability formula :-
, 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 :
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 :-
Hence, the probability there is at least one day in a year when nobody has a birthday =
Y = ln |1 + t - t^3| = (1 - 3t^2)/(1 + t - t^3)
Answer:
y = 2/3x - 3
Step-by-step explanation:
Step 1: Write equation
2x - 3y = 9
Step 2: Solve for <em>y</em>
- Subtract 2x on both sides: -3y = 9 - 2x
- Divide both sides by -3: y = -3 + 2/3x
- Rewrite: y = 2/3x - 3
