Answer:
In a state lottery, you must correctly select 5 numbers (in any order) out of 40 to win the top prize.
1. How many ways can 5 numbers be chosen from 40 numbers?
40C5 = = 658008 ways.
2. You purchase one lottery ticket. What is the probability that you will win the top prize?
The answer is 5! ways or 120 ways.
Hence, probability of winning top prize = =0.0001 or 0.01 %
3. The order of the numbers mattered, will the probability of winning increase or decrease? Why?
The probability decreases.
The probability of winning a game when order matters is always less than the probability of winning a game when order does not matter. This is because the permutation is always greater than the combination.
Answer:
domain : ] -∞ , 2]
Step-by-step explanation:
the value of 2-x must be more than or equal to 0
because you there is no square root for negative number
2-x ≥ 0
x ≤ 2
Answer:
t = -3
Step-by-step explanation:
15 - 6t = -11t
ADD 6t TO BOTH SIDES
15 = -5t
DIVIDE -5 TO BOTH SIDES
t = -3
Do you see how I got t = -3? Do you fully understand it, so if you get another question like this, you won't need help? I hope this helps! :)

Answer:
The greatest number of stamps that Nathan can put on each page = 16.
Step-by-step explanation:
Given:
Nathan has:
80 US stamps
64 Canadian stamps
32 Mexican stamps
The stamps need to put on a page such that each page has same number of same country stamps on each page.
To find the greatest number of stamps he can put on each page.
Solution:
In order to find the greatest number of stamps Nathan can put on each page, we will find the G.C.F. of the three numbers.
The numbers are:
<em>We will list down the prime factors of each number.</em>
The G.C.F can be given as = = 16
Thus, the greatest number of stamps that Nathan can put on each page = 16.
