The mean would be 58!! Basically what you’re doing to get the mean is adding all of the numbers together and dividing by how many you’re adding. In this case, you would add all of the numbers and divide by 8 because you have 8 numbers ! :D
Answer:
Events A and B are not independent.
Step-by-step explanation:
In order for two events to be independent, the following relationship must be true:
The intersection between events A and B is the outcome that Bob and Alice have exactly one girl, the probability is:
For event A, the possible outcomes are having one or two girls:
For event B, the possible outcomes are having none or one girl:
Therefore, P(A) x P(B) is:
Since P(A) x P(B) ≠ P(A∩B), events A and B are not independent
Use PEMDAS. Parenthesis, Exponents, Multiply, Divide, Addition, Subtraction.
So, you'd distribute 5 into the parenthesis, leaving you with 9+20x+20, then add like terms. 20x+29
Answer:
28 sides
Step-by-step explanation:
The sum of the interior angles of a polygon is
sum = 180(n - 2) ← n is the number of sides
Here sum = 4680 , thus
180(n - 2) = 4680 ( divide both sides by 180 )
n - 2 = 26 ( add 2 to both sides )
n = 28
