Answer: E(Y) = 1.6 and Var(Y)=1.12
Step-by-step explanation:
Since we have given that
X 0 1 2
P(X) 0.4 0.4 0.2
Here, number of games = 2
So,
Since are independent variables.
so,
So, we get that
So, E[y]=2×0.8=1.6
and Var[y]=2×0.56=1.12
Hence, E(Y) = 1.6 and Var(Y)=1.12
Alright, lets get started.
The Denver office has 137 employees with an average salary of $67,013.
So the total salay of all employees at Denver office will be =
So the total salay of all employees at Denver office will be = $ 9180781
The Anchorage office has 25 employees with an average salary of $71,332.
So the total salary of employees at Anchorage office will be =
So the total salary of employees at Anchorage office will be = $ 1783300
So, complete total salary of employees at both offices will be =
So, complete total salary of employees at both offices will be = $ 10964081
Total number of employees at both offices are =
So, the average salary of employee across the company =
So, the average salary of employee across the company = 67679.5
Rounding off,
So, the average salary of employee across the company = $ 67680 : Answer
Hope it will help :)
Answer:
The error interval for x is:
Step-by-step explanation:
In order to determine the error interval for x, We have to get the all the number which could be rounded off to .
These number can be listed in order such as:
15.375 15.376 15.377 15.378 15.379 15.380 15.381 15.382 15.383 15.384
Therefore, the error interval for x is:
Step-by-step explanation:
Since we have given that
Number of muffins Diana sold at the bake sale = 336
Number of muffins Bob sold at the bake sale = 287
Now, here we are using the method of estimation i.e. rounding the integers to nearest ones.
By estimation, we get
Number of muffins Diana sold at the bake sale = 340
Number of muffins Bob sold at the bake sale = 290
So,
Difference between them is given by
Hence, Bob sold 50 fewer muffins than Diana.
Answer: The correct option is 1.
Explanation:
The given piecewise function is,
It means if x<0, then
If , then
Since the f(x) is defined for x<0 and , therefore the function f(x) is not defined for
.
From the graph 2, 3 and 4 we can easily noticed that for each value of x there exist a unique value of y, therefore the function is defined for all values of x, which is not true according to the given piecewise function.
Only in figure the value of y not exist when x lies between 0 to 2, including 0. It means the function is not defined for , hence the first option is correct.
