6P3 => 6!/(6-3)! = 120.
I can't very well explain, but I hope it works.
Ok you’ll know that it’s 0.31%
Explanation:
The process is start by making it into a fraction, 2/650 then divide 2 by 650 to get 0.0031 (I rounded up) which to make it into a percentage, you move everything two spot closer to the “.”
0.31 then add a % and bam that’s the answer.
Hope this helps!
Answer:
See below.
Step-by-step explanation:
Let's look at the cost for members (C1) first. Let x be the number of visits.
C1(x) = 12 + 8x
For non-members (C2), we can do the same.
C2(x) = 10x
You can graph these two equations.
x C1 C2
0 12 0
1 20 10
2 28 20
3 36 30
4 44 40
5 52 50
6 60 60
7 68 70
Let's make the two equations equal, to find out where the benefit is the same.
12 + 8x = 10x
2x = 12
x = 6
Up to 5 visits, the non-member cost is better. At 6 visits, there's the same price. For more than 6 visits, the member cost is better.
Find the change in the y coordinates
7-5=2
Find the change in the x coordinates
1--3 or 1+3= 4
Divide the changes in the y and x coordinates
2/4= 1/2
The slope is 1/2. Hope this helps!
