Answer:
I will use numbers only. You draw the diagram!!
Just multiply: 7 people x 2/3 =14 / 3 = 4 2/3 = 5 - pizzas - since you can't order 2/3 of a pizza!!.
5 - 4 2/3 = 1 / 3 of a pizza will be "leftover"!.

Answer:
11,800 different four letter permutations can be formed using four letters out of the first 12 in the alphabet
Step-by-step explanation:
Permutations formula:
The number of possible permutations of x elements from a set of n elements is given by the following formula:
In this question:
Permutations of four letters from a set of 12 letters. So
11,800 different four letter permutations can be formed using four letters out of the first 12 in the alphabet
Answer:
C
Step-by-step explanation:
Imagine folding the paper at the x-axis line
you will see the base of the triangle will be at (1, -1) and (3, -1), and the top of the triangle will be reflected at (1, -3)
Option C matches the description
I believe it is 4. I am not 100% sure
Answer:
0.109
Step-by-step explanation:
Probability is expressed by the number of desirable outcomes over the total outcomes. The total outcomes would be 2^8 because there are two possibilities in each flip, and using the fundamental counting principle, you get 2^8 total outcomes. Next, to find the amount of situations where you only flip two tails, you use 8 choose 2 because we are looking for the amount of ways you can choose 2 out of the 8 to be tails. 8 choose 2 is the same as:
8! / (6! x 2!) - 28
So, the probability is:
28 / 2^8 or 28/256
As a decimal, this is: 0.109375
And rounded to the nearest thousandth it's 0.109
