Answer:
Simplified: 40
Step-by-step explanation:
To simplify this, we need to first separate the terms in this expression. There is a property of exponents that says: We can do this same thing to simplify this expression. Next, we can simplify each of these terms.
simply becomes 4. In the other term, the
simply cancel each other and leave the 10. This means that we're left with 4*10, which is 40
Answer: 504
Step-by-step explanation:
When we select r things from n things in a order , we use permutations.
Formula for permutation:
Given : The number of family members who are potential kidney donors. = 9
Number of people needed to be selected for best match, a second-best match, and a third-best match ( in an order)=3
Then, the number of possible orders are =
Hence, the number of possible orders 504.
Answer:
Step-by-step explanation:
Geometric formula sequence:
(where is the first term of the sequence and
is the common ratio)
To find the common ratio, divide one of the terms by the previous term:
From inspection,
Therefore,
