For this example, we must combine not permutate; this because a salad in which you first use apple then tomato is the same as the one in which you use first tomato then apple, so order does not matter.
Me must do "10 combine 7" which is written by the binomial coefficient
; in general a binomial coefficient is written by:
In which
and
are positive integers, such that
.
So, for this problem:
Hence, there are 120 different ways to make the fruit salad.
Answer:
500
Step-by-step explanation:
I had the same question this week trust
Answer:
"Snack B and C are same ratio"
Step-by-step explanation:
We need to reduce each fraction and determine whether the ratios are same or not.
3/150 = 1/50
Checking A:
2/75 = 1/37.5
So, this is not equal to 1/50
Checking B:
4/200 = 1/50
THis is the same, so this is equal to 1/50
Checking C:
1/50
it is directly given, so this is equal as well
Hence, Snack B and C are same ratio.
= (-1/3) + 7/4
= -4/12 + 21/12
= 17/12
