Answer:
1. $2,950.62
2. $93.75
Step-by-step explanation:
Ann took out a loan of = $12,000
At an interest rate of = 5.65%
Time = 4 years
Formula of compound interest = 
= 
= 
= 12,000 × 1.24588514
Interest = Amount - principal amount
= $14,950.62 - 12,000
= $2,950.62
Amount that Dan borrowed = $1,250
rate of interest = 5%
Time = 18 months or 1.5 years
Formula of simple interest = P(1+rt)
= 1250(1+(0.05 × 1.5))
= 1250(1+0.075)
= 1250 × 1.075
= 1343.75
Interest = Amount - principal
I = 1343.75 - 1250
= $93.75
The answer is B: Yes because each input has only one output
Answer:
The answer is 10,800
Step-by-step explanation:
12,000 - 10% = 10800
Answer is b. A calculator to work out the answer
By 32,760 different ways can a researcher select 4 rats from 15 rats and assign each to a different test .
<u>Step-by-step explanation:</u>
We need to find How many different ways can a researcher select 4 rats from 15 rats and assign each to a different test.Let's find out:
We will use Permutation here : As we will chose 4 rats out of 15 rats , order will be considered which will make this as a permutation problem . Formula for permutation is given by :
⇒ 
According to question , we have
⇒ 
⇒ 
⇒ 
⇒ 
⇒ 
Therefore , By 32,760 different ways can a researcher select 4 rats from 15 rats and assign each to a different test .
