Y=-5.11111 how I solved it is in the picture attached
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 =
Given:
The algebra tiles of an equation.
To find:
The equation represented by the given model.
Solution:
On the left side of the model we have 4 tiles of (-x) and 3 tiles of (-1). So,



On the right side of the model we have 8 tiles of (-1). So,


Now, equate the LHS and RHS to get the equation.

Therefore, the equation for the given model is
.
Answer: for the first one it is the ll because on the first one it measures 80 degrees for both angles and so for the the second just that it's 90 degrees
For the second 2 questions the are parallel because they don't join together but go straight until infinite.
Step-by-step explanation:
Answer:
Part A=0.67
Part B=0.72
Ill need you to show me the choices for part C if you want to know the answer. You can edit the question.
Step-by-step explanation:
Part A=find the adults that want white choclate and divide that over the total of people buying white chocolate.(52/78) And turn to decimal since they want it in hundredths and round.
Part B=basically the same thing just with different variables, you should get 105/146.
