Answer:
120
Step-by-step explanation:
Since we're dealing with a problem where the order matters and the first two letters are already chosen we need to subtract the number of letters and the number of available slots per group.
We use the permutation formula to find the answer, but before that let's check values.
n = 8
k = 5
Now since there are two letters already chosen we have to deduct two from both the value of n and k.
n = 6
k = 3
Now we can use the permutation formula:
The 3*2*1 cancels out and leaves us with:
So there are 120 possible ways to arrange eight letters into groups of five where order matters and the first two letters are already chosen.
Answer:
the answers that are equivalent are a, b, and e
Answer: -5
Step-by-step explanation: 19 -9 = 10. 10/-2 = -5
Set up an algebraic equation. This is what it looks like based on what the question tells you:
Let a = area of pentagon
a+27 = 4a-15
3a-15 = 27
3a = 42
a = 14
Answer:
The correct answer is: C. The value is a statistic because the 6076 adults in public restrooms are a sample.
Step-by-step explanation:
A sample statistic is a piece of statistical information you get from a part of a population. In this case, 6076 adults in public restrooms.
Now you have recognized the sample, and you infer some measure from this sample. In this case, 23% did not wash their hands before exiting.
