A wallet contains five $10 bills, three $5 bills, six $1 bills, and no larger denominations. If bills are randomly selected one-
1 answer:
Answer:
Step-by-step explanation:
Another way of phrasing this question is this; if only two bills are selected without replacement, what is the probability that at one of the two bills will be a $10 bill:
P(One $10 bill) = P(picking a $10 bill first then another type) + (picking another
type then a $10 bill)
=

The equation is an illustration of a linear function
The rate of change is 10 and the initial value is 25
<h3>How to determine the rate of change and the initial value</h3>The equation is given as:
A linear equation is represented as:
Where:
- b represents the initial value
- m represents the rate
By comparison:
b = 25
m = 10
Hence, the rate of change is 10 and the initial value is 25

Answer:
we need to prove : for every integer n>1, the number is a multiple of 5.
1) check divisibility for n=1, (divisible)
2) Assume that is divisible by 5,
3) Induction,
Now,
Take out the common factor,
(divisible by 5)
add both the sides by f(k)
We have proved that difference between and
is divisible by 5.
so, our assumption in step 2 is correct.
Since is divisible by 5, then
must be divisible by 5 since we are taking the sum of 2 terms that are divisible by 5.
Therefore, for every integer n>1, the number is a multiple of 5.
