Answer:
Domain is 8 to 15 broomsticks
Range is 1,200 to 2,250 Galleons
Step-by-step explanation:
Here, when we talk of the domain, we are simply referring to the range of values of the number of broomsticks to be bought which is between 8 and 15
When we talk of the range, we are talking of the amount these broomsticks will cost
The cost for 8 broomsticks will be 8 * 150 = 1,200 Galleons
15 broomsticks will cost 15 * 150 = 2,250 Galleons
The range here will thus be 1,200 Galleons to 2,250 Galleons
Answer:

Step-by-step explanation:
The standard compound interest formula is given by:

Where A is the amount afterwards, P is the principal, r is the rate, n is the times compounded per year, and t is the number of years.
Since we are compounding annually, n=1. Therefore:

Lester wants to invest $10,000. So, P=10,000.
He wants to earn $1000 interest. Therefore, our final amount should be 11000. So, A=11000.
And our timeframe is 3.3 years. So, t=3.3. Substituting these values, we get:

Let’s solve for our rate r.
Divide both sides by 10000:

We can raise both sides to 1/3.3. So:

The right side will cancel:

So:

Use a calculator:

So, the annual rate of interest needs to be about 0.03 or 3% in order for Lester to earn his interest.
This requires us to find the number of permutations of 6 different bands taken 2 at a time:
