As you have a 1/2 chance of getting what you want when you flip the coin, to get heads, heads, tails, tails will be 1/2 x 1/2 x 1/2 x 1/2. Working our way down the line, 1/2 x 1/2 = 1/4, 1/4 x 1/2 = 1/8, and 1/8 x 1/2 = 1/16. Jack will get heads, heads, tails, tails 1/16 of the time.
Answer:
60
Step-by-step explanation:
<u>Step 1: Solve for x</u>
x + 3x + 2x = 180
6x / 6 = 180 / 6
x = 30
<u>Step 2: Find the measure of angle C</u>
Angle C = 2x
Angle C = 2(30)
Angle C = 60 degrees
Answer: 60
Answer:
4n²+2n as a factorial is given as:
Step-by-step explanation:
We are given an expression which has to be converted into factorial form.
The expression is as follows:
Now we know that 2n+1 and 2n differs by '1' and the next smaller term is '2n-1'.
Hence, multiplying and dividing by '(2n-1)!'; we get:
we know that x(x-1)(x-2)! = x!, so:
