A binomial distribution has the following properties;
1. There is a fixed number of trials.
2. Each trial is independent of the others.
3.Each trial has a constant probability of success.
4. There are only two possible outcomes, 'success' and 'failure'.
Statements B and D meet the requirements for the variable X to have a binomial distribution.
Answer:
x = 15°
Step-by-step explanation:
The secant- tangent angle x is half the difference of the intercepted arcs, that is
x =
(80 - 50)° = 0.5 × 30° = 15°
Answer:
It would be very difficult to determine the area without any given measurements of the sides. I'm afraid I cannot help you with this question.

Answer:
5040
Step-by-step explanation:
The given series is :
24 + 48 + 72 + 96 +...+ 480
The first term, a= 24
Common difference, d = 24
The last term, 
Let there are n terms in the AP.
So,

There are 20 terms in the series. The sum of 20 terms is :

So, the sum of the given arithmetic series is equal to 5040.
Answer:
The answer is 
Step-by-step explanation:
Volume of the rectangular prism = Length * Width * Height
Length (l) = 
Width (w) = 
Height (h) = 
By substituting these values to the equation above,
Volume of the rectangular prism = 
=
=
=
Therefore,
The answer is
