Answer: Permutation is involved , since order of prizes matters.
The number of different ways the prizes can be awarded =95060
Step-by-step explanation:
Given : Total number of people purchase lottery tickets =100
The number of prizes = 3
Since each prize can be claimed by only one person.
So order matters here, there for we use permutations .
The number of permutations of n objects taken m at a time is given by :-

Then, the number of different ways the prizes can be awarded :-

The answer is 440.
What I do is just take the -11 and -15 out of the parentheses so it is -11*-15 and the answer is 165. Then, you take -11 and -25 out of the parentheses and find the answer.
Add them together.
Hope that helped :)
Answer:
-1
Step-by-step explanation:
Given: Mean= 25 minutes.
Standard deviation= 2 minutes
x= 23 minutes.
Lets find the z-score for the number of sandwiches delivered in less than 23 mins.
Formula: Z-score= 
Z-score= 
⇒ Z-score= 
∴ Z-score will be -1
Hence, -1 is the z-score for the number of sandwiches delivered in less than 23 minutes.

Answer: 18%</h3>
===========================================================
Explanation:
Convert each percentage to decimal form
- 30% converts to 0.30
- 60% converts to 0.60
Then multiply the decimal values
0.30*0.60 = 0.18
That converts to 18%
So there's an 18% chance that both events happen at the same time. In other words, there's an 18% chance of the temperature falling below zero and the bus being late.
Answer:
9x^4+21x+6=0
Step-by-step explanation:
( 3x^2)^2+7(3x +2) -8=0
((3^2)*(x^2)^2)+(7*3x)+(7*2)-8=0
9(x^4)+21x+14-8=0
9x^4+21x+6=0
