Answer:
32760
Step-by-step explanation:
This is a permutation of 15 objects taken 4 at a time. To calculate this, we use the formula:

In our case, n is 15 and r is 4:

Idk I would say 30
Step-by-step explanation:
Answer: Simple interest rate = 3%.
Step-by-step explanation: We are given invested amount = $5000.
Number of years of investment = 4 years.
Interest earned = $600.
Simple interest formula.
I = P R T.
Where I is the earned interest, P is the invested amount , R is the rate of interest and T is the time in years.
Plugging values in formula, we get
600 = 5000 × R × 4
600 = 20000R.
Dividing both sides by 20000, we get

0.03 = R.
Multiplying by 100 to convert it in percentage, we get
0.03 × 100 = R
R = 3 %.
Could you rewrite this please? It is fairly difficult to read.
Answer:
y=2x-6
Step-by-step explanation:
y+4=2(x-1)
Subtract 4 to both sides of the equation:
y+4-4=2(x-1)-4
y=2(x-1)-4
Distribute the 2:
y=2x-2-4
y=2x-6
Where 2 is the slope and -6 is the y - intercept.
