The exact value of f(n - 1) is fn - f
Answer:
Evan is correct
Step-by-step explanation:
To find this answer, we can use the formula A=PxW
A=Part, P=Percentage, W=Whole
We can fill in the numbers we know and leave blank (with the variable) the numbers we want to find out
In this scenario, we want to find out if 25 is 125% of 29
So we can use this formula and do the equation like this:
A=1.25x20
This gets us to 25
So Evan is correct!
Hope this helps and please award brainliest if possible!
Area of the base and the top :(4x7) + (4x7) = 56
Lateral area of the front & the back = (4x12) + (4x12) = 96
Lateral area of the right & left = (7x12) + (7x12) = 168
TOTAL AREA = 56+96+168 = 320
Volume = 4x7x12 = 336
RATIO AREA/VOLUME = 320/336 . Simplify by dividing numerator and denominator by 16. Final result: AREA/VOLUME = 20/21
Answer:
The number of ways to award the prizes if it satisfies the given conditions is 94,109,400.
Step-by-step explanation:
There are 100 tickets that are distributed among 100 different people.
Four different prizes are awarded, including a grand prize.
The selection of the four wining tickets can be done using permutations.
Permutation is an arrangement of all the data set in a specific order.
The formula to compute the permutation of <em>k</em> objects from <em>n</em> different objects is:
![^{n}P_{k}=\frac{n!}{(n-k)!}](https://tex.z-dn.net/?f=%5E%7Bn%7DP_%7Bk%7D%3D%5Cfrac%7Bn%21%7D%7B%28n-k%29%21%7D)
In this case we need to compute the number of selection of the 4 winning tickets accordingly from 100 tickets.
Compute the number of ways to select 4 winning tickets as follows:
![^{n}P_{k}=\frac{n!}{(n-k)!}](https://tex.z-dn.net/?f=%5E%7Bn%7DP_%7Bk%7D%3D%5Cfrac%7Bn%21%7D%7B%28n-k%29%21%7D)
![^{100}P_{4}=\frac{100!}{(100-4)!}](https://tex.z-dn.net/?f=%5E%7B100%7DP_%7B4%7D%3D%5Cfrac%7B100%21%7D%7B%28100-4%29%21%7D)
![=\frac{100!}{96!}](https://tex.z-dn.net/?f=%3D%5Cfrac%7B100%21%7D%7B96%21%7D)
![=\frac{100\times99\times98\times97\times96!}{96!}](https://tex.z-dn.net/?f=%3D%5Cfrac%7B100%5Ctimes99%5Ctimes98%5Ctimes97%5Ctimes96%21%7D%7B96%21%7D)
![=94109400](https://tex.z-dn.net/?f=%3D94109400)
Thus, the number of ways to award the prizes if it satisfies the given conditions is 94,109,400.
