you have enough tickets to play 6 different games at a amusement park. if there are 14 games, how many ways can you choose six?
Musya8 [376]

Answer:

3003 ways

Step-by-step explanation:

You can basically choose 6 games from 14 games in total. This is essential a combination problem. We want the number of ways to choose 6 things from 14 things. The general formula for combinations is:

nCr=\frac{n!}{r!(n-r)!}

Which tells us the number of ways to choose "r" things from a total of "n" things.

The factorial notation is:

n! = n * (n-1) * (n-2) * ....

Example:  3! = 3 * 2 * 1

Now, we know from the problem,

n = 14

r = 6

So, substituting, we get:

nCr=\frac{n!}{r!(n-r)!}\\14C6=\frac{14!}{6!(14-6)!}\\=\frac{14!}{8!*6!}\\=\frac{14*13*12*11*10*9*8!}{6!*8!}\\=\frac{14*13*12*11*10*9}{6*5*4*3*2*1}\\=3003

You can choose in 3003 ways

Sorry for spamming questions
Salsk061 [2.6K]

Answer:

likely

Step-by-step explanation:

Since most of the spots are greater than 100 (only a few are 100 or free spin or bankrupt)  it is likely that you will land on an amount greater than 100


unlikely  would be if there were only a few spots greater than 100

equally likely would be  about 1/2 the spots  greater than 100 and 1/2 not

impossible would be no spots greater than 100

certain would be all spots greater than 100

A grain silo has a diameter of 4.4 meters. The height of its cylindrical portion is 6.2 meters.
erastova [34]
Volume of a cylinder = Height x base are
H = 6.2 m
Bae are = π.R² ; Diameter =4.4 m, then Radius = 2.2 m
Base area = π(2.2)²
And Volume=:
V= (6.2).(π,2.2²) = (6.2).(π)(.4.84) = 30.008.π ≈ 94.2 m³

First thing to do with this problem is to plot the given data in MS excel. We can see in the graph that the minima (lowest point of the graph) is at (4,-2) and the maxima is at (2,3). The critical points are points which the direction changes from one side to another.
