Answer:
There are 14,400 possible ways to do this
Step-by-step explanation:
Here, we have a selection problem. What to use is combination obviously.
For a combination problem, we would be selecting a specific number from a given total. For a case where we have n number of things and we are looking for how many ways to select r number of things, this can be done in nCr ways and this is mathematically equal to n!/(n-r)!r!
For the Diet coke, she has 10 bottles and want to select 3 for tasting, the number of ways she can do this is mathematically equal to 10C3. Computationally this is equal to ;
10!/(10-3)!3! = 10!/7!3! = 120 ways
For the coke zero, we have the same pattern, selecting a total number of 3 out of 10. This means the same 10C3 with the answer being 120 ways also.
Now, the number of ways of selecting from both would be a multiplication of both answers which is 120 ways * 120 ways = 14,400 ways
Answer:
y = 3x + 8
Step-by-step explanation:
Y - 2 = 3 (x +2)
y -2 = 3x + 6
y = 3x + 8
Kelly could buy 4 people the chicken salad, and two people the egg salad. The reason for this is that 4 x $5= $20 and 2 x $4= $8. So, when you add together the total price: $20+$8= $28; which is the exact amount of money she is willing to spend. This answer also fulfils the fact that more coworkers want chicken salad.
8.2 is 10% of 82
As 8.2 * 10 is 82.
Answer:
The formation of the equation is odd, but I assume it's supposed to be:
4k - 10k = -8k
-6k = -8k
-6k + 8k = -8k + 8k
2k = 0
=
k = 0
